PROCESSOR-SDK-AM65X: Loading through JTAG

Hi,

There are several steps being discussed here. I would like to propose falling back a bit.  If allowing the boot to occur as intended out of the SD card say for example is there anything coming out of the console if you don't use JTAG? 

You mentioned skipping tiboot3.bin, this binary loads the sysfw.itb and sets up DDR etc. What is the reason for skipping using this image? You also listed some steps that I am not sure that are needed. For example the M3 step should not be needed but we need to understand what is leading you to think this step is necessary.

Best Regards,

Schuyler

Hello,

As mentioned by Schuyler, I am wondering if you have tried booting from the SD card. If no output is observed on the serial terminal, it is a good indication that the code is stuck in the R5 stage. In order to debug the R5, please add the following line of code in the file "<u-boot_dir>/arch/arm/mach-k3/am6_init.c":

void board_init_f(ulong dummy)
{
#if defined(CONFIG_K3_LOAD_SYSFW) || defined(CONFIG_K3_AM654_DDRSS)
	struct udevice *dev;
	int ret;
#endif
	/*
	 * Cannot delay this further as there is a chance that
	 * K3_BOOT_PARAM_TABLE_INDEX can be over written by SPL MALLOC section.
	 */
	store_boot_index_from_rom();

	/* Make all control module registers accessible */
	ctrl_mmr_unlock();

+       asm("test: nop");
+       asm("       nop");
+       asm("  b test ");
+       asm(" nop");
+       asm(" nop");


	setup_am654_navss_northbridge();

After adding the above code, please compile Uboot and copy the required images on the SD card as mentioned in the following guide. Plug the SD card and boot the board. Once the board is powered on, please connect to the A53 core using CCS (Please make sure no GEL files are loaded). In CCS, load the symbol from the following location "<u-boot_build_dir>/r5/spl/u-boot-spl". At this point, the test should be stuck inside the loop we previously added. Changing the Program Counter will allows us break out of the loop and step through the R5 code.

Lastly, I am assuming you are using a custom board and please share how the DDR is configured for the custom board (Please refer to the following EMIF tool guide).

Regards,
Krunal

Hi Krunal,

Our main issue is that we aren't getting good data over the SD card, so we're looking for an alternate boot method. We can get the kernel to attempt to start, but it will kernel panic or freeze, so the SD card is an unreliable boot source. We also don't always make it out of u-boot before the system freezes. I'll give the test code a try.

Schuyler,

We're not sure where we should be loading tiboot3.bin to through load memory on CCS. It's not being skipped on the SD card side, but the gel files on CCS seem to do all the DDR configuration already, so we're not sure if we need to load it if we're going through JTAG.

Thanks,

Andrea

Hello Andrea,

Please correct me if I am wrong but sometimes you are able to get to the Uboot prompt but Kernel crashes. I am wondering if you could please share the boot logs that way we could inspect it further. Initially, I was under the impression that you are not observing any output on the terminal. Compared to the AM65 EVM, please share the DDR differences in terms of the memory size.

Regards,
Krunal

Hi All, 

I would like to synchronize all sides: 

1. Initialization of DDR4 with GEL file is ok, all RAM tests are ok

2. Booting from SD CARD :  u-boot runs , we see randomize kernel crashes, no known pattern observed. Out tests: 

a.) We start u-boot from SD CARD, most of u-boot starts are ok

b.) We start u-boot command line and we also connect to processor with JTAG in parallel 

c.) We load kernel from SD-card to DDR with u-boot ( command line ) , but we do not start kernel 

d.) we download kernel from DDR to file via JTAG

Result:

If we compare binary kernel file we are loading to DDR with u-boot and downloaded binary from DDR to file via JTAG we see byte erros

Frequency of Byte errors is different with different SD cards in use. Slower SD card , less byte errors

Second test:

- Starting u-boot interrupting auto boot, connecting JTAG.  Loading kernel to DDR and downloading back form DDR, comparing, does not show any diff in files.

Notes:

We measured SD card data integrity and power , results are not so bad. But still we suspect that we have issue with SD card data integrity or controller , this is the reason we are looking for alternative methods. 

We can go step by step, but to speed up: we use SD for debug only, for production we have eMMC on the board. We put way more attention in eMMC routing and signal integrity.

Questions:

What is best and fastest way to program eMMC with JTAG without using SD card?

br,

Ales 

 

1. Initialization of DDR4 with GEL file is ok, all RAM tests are ok 

If you could please share the name of the tests that were ran to verify the RAM.

 We start u-boot from SD CARD, most of u-boot starts are ok 

I just wanted to confirm that you are able to get to the Uboot prompt without any problems. Please keep in mind that there are 3 stages in the bootloader: tiboot3.bin -> tispl.bin -> u-boot.img and here is what successful Uboot prompt looks like:

Regards,
Krunal

Yes we are aware of booting process and yes we are in u-boot prompt. 

SD card is for debug purpose on our board we did not put too much attention to signal integrity. We confirmed the signals on SD card are marginal enough to expect errors.

eMMC is routed with signal integrity in mind, so we need to program eMMC without working SD card interface.

What would you suggest as easiest set up and what is tested on AM65 EVB:

- USB boot mode

-u-boot DFU 

-JTAG programming of eMMC

Br, 

Ales

Hello Ales,

Currently, we have four boot modes tested on the AM65 EVM (SD card, OSPI, eMMC, and UART). Here is a reference document: http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_U-Boot.html#supported-boot-modes 

Also, I am wondering if you have a network interface enabled on the board. If there is a network interface, we could initially boot from UART/SD and copy/flash the images over the network.

Regards,
Krunal

Hi Krunal,

We have network interface ports, though none of them have been verified as working. We will give the TFTP a try.

Thanks,

Hello Andrea,

I will be closing the ticket but if you have any further questions on TFTP, please feel free to open the ticket.

Regards,
Krunal

Hi Krunal,

We've made some progress with the tftp server and it seems like the board is making more progress booting than before. Our system is stopping at the same point every time after loading the tftp files. I have a log attached. Do you know what the AM65 is looking for to continue the boot process?

Thanks,

Andrea

Hi Krunal,

We set that variable and it is still stopping at the same location with the same boot log.

Thanks,

Hello Andrea,

After adding the console commands, could you please share the boot logs again?

Regards,
Krunal

Hi Krunal,

Here is the console boot log. We also ran a diff on the u-boot once it relocated into DDR4 to check if it's the same as the one on the SD card and that looks to be the same except for a byte at the start. We're digging into the rest of the setup for the time being.

Thanks
Andrea

Hi Andrea,

As an experiment, could you please remove all the custom Uboot environment variables using the following command: "env default -f -a;saveenv;reset". Next, please use the following commands to setup NFS boot:

=> setenv serverip 192.168.0.1
=> setenv rootpath /home/psdk_linux/am65xx/ti-processor-sdk-linux-am65xx-evm-06.00.00.07/targetNFS
=> setenv bootfile Image
=> setenv ip_method dhcp
=> setenv nfs_bootfile 'nfs ${loadaddr} ${serverip}:${rootpath}${bootdir}/${name_kern}'
=> setenv nfs_fdtfile 'nfs ${fdtaddr} ${serverip}:${rootpath}${bootdir}/${fdtfile}'
=> setenv nfsargs 'setenv bootargs console=${console} root=/dev/nfs nfsroot=${serverip}:${rootpath},v3 rw ip=dhcp' 
=> setenv bootcmd 'setenv autoload no; dhcp; run nfs_bootfile; run findfdt; run nfs_fdtfile; run nfsargs; booti ${loadaddr} - ${fdtaddr}'

Regards,
Krunal

With regards to the Uboot environment variables, you have the following command: "init_net=run args_all args_net; setenv autoload no; dhcp". The previous command, first runs "args_all" and sets the optargs to "earlycon=ns16550a,mmio32,0x02800000". Next, it will run the command "args_net" and set the bootargs to "earlycon=ns16550a,mmio32,0x02800000 + rootfstype=nfs root=/dev/nfs rw nfsroot=${serverip}:${nfs_root},${nfs_options} ip=dhcp". 

As you can see, you are basically overwriting the bootargs command you defined in the following variable: "bootargs=earlycon=ns16550a,mmio32,0x02800000 rootfstype=nfp (<--should be equal to nfs) console=ttyS2,115200".

Regards,
Krunal

Thanks for looking through the logs. We tried both options. With the nfp fix, it still resulted in the same behavior of freezing at the 'bootconsole [disabled]' message.. With the default environment, we saw that it downloaded the filesystem off of the targetNFS location but it would freeze right at the starting kernel message.

Thanks,
Andrea

Hi Andrea,

Could you please share the boot logs?

Regards,
Krunal

Hi Krunal,

Here is the log from setting the variables to default and then setting the variables from the previous message. It looked as if it downloaded a lot more data than our previous tests, but it froze very soon after and didn't give us a lot of information to work with.

Thanks,
Andrea

Hello Andrea,

I am wondering if you have any updates.

Regards,
Krunal

Hi Krunal,

Not many updates at the moment. We're digging into the device tree files at the moment since we don't have a lot of the hardware the evm board supports and we're also running into kernel panics. Here's one log we had yesterday, but the panics aren't consistent. Oftentimes we're getting a bad page state in process swap errors. 

Thanks,
Andrea

Hello Andrea,

Are you still experiencing the Kernel panics and do you have any questions regarding the DT files?

Regards,
Krunal

Hi Krunal,

We are still experiencing the kernel panics. I've also posted a related question just now about something we think may be triggering the errors before the DT files come into play.

Thanks,
Andrea
