[OMAPL137] debugging my board through armubl

Hi Flamingo,

Have you changed anything in the new revision of the board?

Because if the earlier board works for the same combination of armubl and gel file, then shouldnt it work with the same  code for the new board?

Maybe ,then the problem exists at the hardware side.

Something like the chip select of FLASH does not go low actually for the time when it should be reading data from flash.

Have you tried probing the signals on CRO?

Regards,

Sid

Flamingo,

Can you verify that the devices on the new boards have the same ROM code revision as your previous batch of boards?

It should be possible to insert similar pleaseWait loops in the ARM UBL by polling a specific address location (with a pointer) that you can poke through CCS.

I'm not sure how to check the ROM code version, but I know that the rev of OMAP is different. We had early release chips with SPI problems, etc. The current board uses revision 2 of the silicon.

I'm not sure I was clear about the issue: the old version of the board boots with both Winbond and Numonyx parts. The new version boots with Winbond, but not Numonyx.

I'm able to use the dsp spi flash writer project to flash all of the parts and I perform a full verify (wrote my own). The dspais, armubl, uboot, and kernel are the same on both flash brands.

I'm still investigating...

It sounds like the L137 and SPI flash are ok since you can program and read-verify from them.  The ROM image has been updated between Rev 1.x and Rev2.0, but the SPI boot mode should be backward compatible.  In case you run out of debug options, can you try the new AISGen revision? http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=sprab04d

I was mistaken when I said that dspais worked and armubl didn't. Instead, I've discovered that dspais is not running either. I've continued diagnosing, and I'm not sure that I've identified the problem, but I've found something curious. I'm hoping someone at TI can tell me if this might be my problem.

I captured SPI traffic from the ROM boot for the OMAP-L137. I have no source code, but it was performing a (slow) read of flash starting at location 0, so I modified my version of the dsp-spi-flash-writer to perform its verify using a slow read (0x3 instead of the fast read 0xb). I then captured the dsp-spi-flash-writer traffic on the scope to see how it differs from the traffic during ROM boot. (I thought it might be an SCLK problem, since the Numonyx part is slower than the Winbond part.)

In the file "tek00002.tif" you see the dsp-spi-flash-writer's version of a slow read from location 0. At the top of the display, you see the full buffer. The bottom is the zoomed section within the gray brackets. The magenta trace is the chip select. The green trace is the SIMO (M=OMAP). The cyan trace is the SOMI (S=Numonyx M25P128). The yellow trace is SCLK. At the bottom of the display, note that the SCLK frequency is 622.4kHz. (approximately matching my planned SCLK).

In the file "tek00003.tif", you see the ROM boot's version of the same thing. The first thing you'll notice is that the SCLKs are not differentiatable at this zoom factor. That is, the SCLK in the ROM boot is much faster. In reality, it is about 10MHz. (within spec for the chip) You may also notice that there are several groups of SPI traffic. The first 3 groups each have 8 bytes and they are slow reads of 4 bytes each at 0, 4, and 8. The two groups of 4 have no new SIMO command, so are continued reads.

In the file "tek00004.tif", you see a closeup of the last group of 4 and the last group of (very fast) 8 SCLKs.

Finally, in file "tek00005.tif", I zoom into one of the fast SCLK groups. In this shot, the SCLK is about 77 MHz. This is beyond the tolerance of the

Numonyx part. The command appears to be a slow read again (0x3). The Numonyx part is responding, but the SCLK does not meet the spec for the part. There is no more SPI traffic on the trace.

I'm not sure what the logic is within the ROM boot program. I don't know why it is changing the SCLK speed. I don't know if additional SPI traffic appears at a much later time (after the scope's buffer).

Please let me know if this is just an artifact of some logic that I'm unaware of or if this is an indication of a problem. (In the meantime, we're trying to order more Winbond parts.)

Flamingo,

Can you repost the pictures?  I do not see any.

How fast is the DSP running when you measure the SCLK?  I'm surprised that you are measuring 77MHz.

The files are on the "Files" tab on my profile page. Their names are referenced in the text of my post. (Don't bother with other files that you see.)

Sorry, I didn't see the second question in your post. The majority of the circuitry on our board matches the EVM board that we got over a year ago. I don't have the circuit diagram near me, but I'm guessing that the OMAP has a 300 MHz clock. Did you find the photos from the scope measurements?

Flamingo,

Can you verify the bootmode with the SYSCFG_BOOTCFG register?  SPI should not be running that fast during hardware ROM boot.  Can you try to flash a while(1) / NOP type of program into SPI and boot into that?

-Tommy

When I set the switches in the position that I believe should boot from SPI flash, BOOTCFG = 0xe37d. When I set them in the position that I believe should allow me to run spi-flash-writer, BOOTCFG = 0xe3ff. I'm flipping two switches, so that makes sense.

These same settings "work" (SPI Flash boot succeeds) on a board that has the Winbond part.

spi-flash-writer works on both Numonyx and Winbond boards. I've modified spi-flash-writer to perform a full verify when I write each component to the Flash chip. All verifies pass. (Although my clock is much slower than I'm seeing during SPI Flash boot.)

If I understand your problem description, it seems to be the SPI0 peripheral frequency that is breaking the boot process.  What I can't figure out is how the SPI is operating at such a high frequency.  If we can use a dummy boot program that does not configure the PLL or any other functions, I would expect the SPI to stay at a reasonably slow frequency.  If that is the case, then it will be a process of finding out what part of the setup is configuring the SPI module to 77MHz.

-Tommy

First a recap, and then some questions.

I can successfully run the spi-flash-writer when the switch settings are set for that. I do use a GEL file when I connect for spi-flash-writer. I presume that the ROM bootloader does not try SPI accesses in this case. Therefore, the SPI setup is based on what occurs in the spi-flash-writer code (and the GEL file). Slow reads, fast reads, and writes all work.

I can not successfully boot when I have the switches set for SPI flash boot. I presume that the ROM bootloader does perform the SPI setup in this case. It successfully performs 32 SPI accesses with an SCLK that is at an acceptable frequency. The 33rd SPI access is attempted with a SCLK frequency that is too high. If you look at the top of the tek00005.tif file, you see the entire capture buffer in miniature. The SCLK is the yellow trace. You see one "spike" on the trace followed by 32 accesses that "work" and 8 accesses that probably don't. No other SPI accesses appear within the captured buffer. The lower part of tek00005.tif is a closeup of one of the fast accesses.

Note that the SPI captures are the first accesses triggered after a boot. If I connect after the failure, the program counter is still in the 0x007xxxxx memory space (at the IDLE statement). I believe this means that it never executes the DSPAIS code, which is at 0x80010000. If I reset after connecting, I can step through the ROM bootloader and it ends up at the same program counter setting. In the instance of stepping through the sequence, I do not necessarily expect the boot to succeed because there are probably timing loops in the ROM bootloader that may not survive the stepping process.

I have no source code for the ROM boot, but somewhere between the 32nd and 33rd SPI access, something bad has happened. Each of the first sets of 8 are 4-byte reads at SPI addresses 0, 4, and 8. In each instance, the read command is issued (4 of the bytes) and 4 bytes are read (the other 4 bytes of the 8 byte sequence). That is, there are 3 slow read commands. The next two groups of 4 are continued reads (from the read at address 8. That means that they are reads of 4 bytes each for address 0xc and 0x10. The ROM bootloader has successfully read 0x14 bytes from the SPI flash. The next SPI activity occurs with the higher SCLK. This appears to be another slow read at address 0x14. This would represent the next address, but it should also be a clue as to what code is executing because, rather than just continue the slow read without reissuing the command, the code that is running opted to reissue the read command.

That is, the spi traffic out of the OMAP is

0x03 0x00 0x00 0x00 (slow read at 0) followed by 4 sets of SCLK to read 4 bytes

0x03 0x00 0x00 0x04 (slow read at 4) followed by 4 sets of SCLK to read 4 bytes

0x03 0x00 0x00 0x08 (slow read at 8) followed by 4 sets of SCLK to read 4 bytes

4 sets of SCLK to continue reading at addresses 0x0c through 0x0f

4 sets of SCLK to continue reading at addresses 0x10 through 0x13

<<<<<something bad happens>>>>>>>

0x03 0x00 0x00 0x14 (slow read at 0x14) followed by 4 sets of SCLK to read 4 bytes

Now to the questions...

You would like me to write an infinite loop and execute it. The loop will not have SPI accesses in it. I'm not sure what you want the switch settings to be, but I'm assuming that you want to remove DSPAIS code from the equation. In that case, I would flash my infinite loop as dspais, change the switches to the SPI flash boot setting and run the ROM bootloader again. I believe that the result will be the same as that described above (because I believe DSPAIS never runs.) Is that the scenario you envision?

Your message suggests that you want to replace the ROM bootloader with the infinite loop, but I don't know how to do that. That is, to the best of my knowledge, the ROM bootloader will run no matter what.

One possibility is that, you want me to load the infinite loop instead of the spi-flash-writer and that you then will assist me in adding in the code for the ROM bootloader, one little chunk at a time until the spi clock goes nuts. Is this the scenario you envision?

I rounded up an old board (with Rev 1 OMAP) to look at the SPI timing on it. I intentionally disconnected the ethernet cable so that u-boot would not successfully boot.

This is a board that one of our engineers uses regularly, so I believe the boot process works on it (if the ethernet cable is plugged in). All I wanted to do was to verify the "backwards compatibility" of the SPI boot process. I am only interested in the SCLK speed, so I didn't bother hooking up leads to SIMO, SOMI, and chip select.

Needless to say, the spi traffic bears no resemblance to that captured on the Rev 2 part. For example, I see 4 groups of 5 byte accesses (for a total of 20 bytes) instead of the 3 groups of 8 and 2 groups of 4 followed by the fast accesses. All 20 of the spi accesses have an SCLK frequency of less than 1Mhz. I don't see any traffic after that, so I can't compare the behavior of the 33rd byte access.

The SPI clock for the first several bytes on the Rev 2 OMAP occurred with a SCLK of about 10 MHz, so something has changed.

We need a dump of the first 32 bytes of your boot image (0x00-0x20 of the flash).  There is obviously an AIS command in that region that is causing different behavior on rev1 parts versus rev2 parts. Can't think what it could be, but we will know it when we see it.

I'm assuming that "boot image" means dspais. An output of the command "od -cx dsp-spi-ais.bin" follows. Note that I think we have not changed this file from the original distribution that came with the development kit. (I can't find a CCS project for it on my system or in our repository.) The spi-flash-writer project (dsp) says that the offset for dspais is 0, so I'm assuming it is stored at offset 0 in the SPI flash.

I'm assuming that "boot image" means dspais. An output of the command "od -cx dsp-spi-ais.bin" follows. Note that I think we have not changed this file from the original distribution that came with the development kit. (I can't find a CCS project for it on my system or in our repository.) The spi-flash-writer project (dsp) says that the offset for dspais is 0, so I'm assuming it is stored at offset 0 in the SPI flash.

The 3rd through 5th words of the AIS image are setting the prescalar of the SPI module to 0, which is not a supported setting of the SPI module.  The prescalar should be 0x2 or higher (the ROM defaults the value to 0x0E).  Why this is causing the exact timing issue you are seeing, I can't say exactly.  As a workaround, try updating the dspais image so that the fifth word of the image (at offset 0x10) is not 0x00000000, but rather 0x0000000E.  Alternatively, you can remove the third, fourth, and fifth words entirely.  Then reflash the image to the SPI flash and try booting.

We will need to report this issue with the dspais file to the appropriate team, assuming that the workaround mentioned above fixes the problem.

I found the dspubl project and even found where the prescaler was set. I changed it and rebuilt, but the generated code was .out, not .bin. I downloaded the AISgen tool. That is where things started to fall apart. The instructions said to type

hexgen -romid D800K001 -seqread -crc 1 -spiclk 0 -appln <PATH to ubl-spi.out or ubl-nand.out> -output <dsp-spi-ais.bin or dsp-spi-ais.bin>

in the directory of the installation.

I tried that, but "hexgen" is not recognized. If the files in that directory, I tried "HexAIS_OMAP-L137.exe", which seemed like the likely choice. It does not understand the "-romid". I read the help and formatted the command:

HexAIS_OMAP-L137.exe -otype binary -o dsp-spi-ais.bin <input file>

It gave me the error "No ini file provided. Using default. OMAP-L137.ini

File OMAP-L137.ini not found.

I'm not sure where to go from here. Can you point me to an AISgen tool installation that provides the hexgen executable? Or a different tool to convert the .out to .bin?

My intention was not for you to rebuild the dsp-spi-ais file, but rather just edit the binary you already had.  That hexgen command line is from the tools that were originally distributed for the version 1.0 ROM.  The HexAIS tool is distributed for the new ROM revision.

If you want an INI file, use the following content:

<begin INI file>

; General settings that can be overwritten in the host code
; that calls the AISGen library.
[General]

; SPIMASTER,I2CMASTER,EMIFA,NAND,EMAC,UART,PCI,HPI,USB,MMC_SD,VLYNQ,RAW
BootMode=SPIMASTER

; 8,16,24 - used for SPI,I2C
AddrWidth=24         

; NO_CRC,SECTION_CRC,SINGLE_CRC
crcCheckType=SECTION_CRC


[AIS_SeqReadEnable]

; This section lets us configure the peripheral interface
; of the current booting peripheral (I2C, SPI, or UART).
; Use with caution. The format of the PERIPHCLKCFG field
; is as follows:
; SPI:        |------24|------16|-------8|-------0|
;             |           RSVD           |PRESCALE|
;
; I2C:        |------24|------16|-------8|-------0|
;             |  RSVD  |PRESCALE|  CLKL  |  CLKH  |
;
; UART:       |------24|------16|-------8|-------0|
;             | RSVD   |  OSR   |  DLH   |  DLL   |
[PERIPHCLKCFG]
PERIPHCLKCFG = 0x0000000E

<end INI file>

I would still recommended simply editing the binary you have as indicated in the previous post.

Regards, Daniel

I understood your intent, but I'm not sure what tool to use to edit the .bin file. Is your suggestion that I put a breakpoint in the spi-flash-writer code and edit the buffer after I've read the record? If so, is there a CRC or checksum that I would have to edit? I would certainly have to edit the buffer again when I run the verify step (which I've modified to perform a real verify).

Use a hex editor. See here for a list of available programs.  I personally use TinyHexer on Windows.

Regards, Daniel

Didn't work, but I'm comparing the data to the hex dump I gave you. There is byte swap going on, so that the SPI bytes are 0x5449, 0x5041, etc. The last byte is 0x0E, but should it be the next-to-last-byte?

The SPIFMT0 is still 0x00020008 after the processor hangs, suggesting that the prescaler is still 0.

In byte order, an AIS file will appear as follows:

So based on your earlier post, yes I believe there is some ordering issue you may need to overcome (depending on what program you are using to edit and view the binary contents). Note that the above was generated using the ini data I provided in the earlier post, in conjunction with the HexAIS tool for OMAP-L137.

Regards, Daniel

Okay, thanks. I reproduced that and the SPI clock stays a normal speed. Unfortunately, the code still doesn't boot. 'm not sure if I have a similar problem with the armubl or if the reads from the SPI are giving me corrupt data. I'm working on that. (If you know of any similar magic byte for armubl, please let me know.)

Two questions:

1. Does armubl have a similar SPI CLK prescaler stored in a location that I can view?

2. I tried to follow the AISgen directions that I found online (http://processors.wiki.ti.com/index.php/Flashing_the_C6747#Generating_Boot_Script_.28AIS_image.29), but the instructions don't match the files I downloaded from the link on the page. (I have files AISgen.exe and HexAIS_OMAP-L137.exe.) Could you give me the instructions that would work with the version downloaded from the link? Or could you post the correct link/instructions?
