SPI Boot

Hi

sorry - which device is this for? and can you specify which example exactly you are referring to? 

Best Regards

Santosh Athuru

Hello,

Thanks for your reply.

I'm having TMS320F28063 device.

In controlSUITE 3.3.9 which I'm having, in that, path is "controlSUITE\libs\utilities\boot_rom\2806x\2806x_boot_rom_v1_1" a program is given for boot ROM.

I getting errors of memory. I have attached the image of problem window. 

Please guide me where I'm getting it wrong.

Hi,

I do have the "TMS320x2806x_boot_rom_lnk.cmd" linker file. I have changed the device properties "general/ main" to TMS320F28063. 

I was getting error of "Flash2806x_API_V100.lib" file not found. I tried to include the path"C:\ti\controlSUITE_Latest\controlSUITE\libs\utilities\flash_api\2806x\v100a\lib", but after copying the "Flash2806x_API_V100.lib" in the project, the errors reduced. I have attached the image of problems window.

Is the FlashAPI library required ? As I understand the FlashAPI for F28063 devices is in the Boot ROM.

For loading the firmware from SD card is this SPI Boot program only required to be loaded ? or can I use it with my other programs ? and then switch the pins of TRST, TDO and CMP2OUT pins.

Please guide me.

Hello Santosh Sir,

I'm still not clearing getting how to implement a SPI bootloader from SD card. I have seen the settings of TRST=0, OTP KEY=0x005A, OTP BMODE=0x0004 for SPI boot mode select having GPIO37=1, GPIO34=1, as referred in the technical manual.

I'm not getting what is OTP KEY and OTP BMODE ?

And after having a .hex/.out of a program will be sufficient or a bootloader program is also required to be loaded in the F28063 device.

If a bootloader program is required then which example program should I refer ?

Please help.

Sir,

What changes in the program is required to detect SPI boot. As you had suggested 

"the ROM project is not for rebuilding. Please refer to C:\ti\controlSUITE\device_support\f2806x\v151\F2806x_examples_ccsv5\f28069_flash_kernel and you can modify it for SPI as needed."

I have changed the following the following in the code:

extern Uint32 SPI_Boot();

   return SPI_Boot();

I'm getting error when I build the program. The console data:

_GetWordData ./SPI_Boot.obj

>> Compilation failure
makefile:150: recipe for target 'f28069_flash_kernel.out' failed
error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "f28069_flash_kernel.out" not
built
gmake: *** [f28069_flash_kernel.out] Error 1
gmake: Target 'all' not remade because of errors.

Please suggest the necessary changes.

For the emulation boot, debugger is required. Refer to pages 204/205 of the TRM: www.ti.com/.../spruh18f.pdf

Sir,

Does debugger mean JTAG?

Do I need to set the GPIO37 and GPIO34 pins first ? as for Emulation Boot they are having don't care states.

How is the EMU_BMODE value changed to "0x0004" ?

Do I have to Debug with the JTAG connected and do a CPU reset and then resume the program?

Please help me understand the SPI boot, having .hex file in micro SD card

Sir,

Thanks for taking your time and giving responses for my quires.

I'm checking the SD card boot with the JTAG connected and CCS is opened. I have seen TRST pin goes high. I have changed the "0xD01" location to "0x0004" in both the GEL file and from memory browse.

The program doesn't seem to get updated from .hex file which is in SD card. I debug from CCS and then resume (run) the program. I have changed the Emulation to EMULATION_BOOT_FLASH.

Do I need to change the program also to enable SD card boot ?

Please suggest the necessary changes.

I suggest stepping through the boot and debugging from there.

Sir,

Please can you tell me how to debug the boot?

One of the TI employee suggested me:

I do not think intel hex is the proper format. I believe we use our our TI hex.

To load the EEPROM, you will need to write the hex file to the EEPROM using SPI.

The SPI booloader is written to download the hex file from the EEPROM. This boot loader source code is available in controlSUITE.
controlSUITE/libs/utilities/boot_rOM

You can look at that source code and reverse engineer a solution to write to the EEPROM.

We have an i2c eeprom example in controlSUITE. 

You can also see the sci_flash_kernel as an example of how to perform a firmware update. Also www.ti.com/.../sprabv4a.pdf

Sir,

Thanks for the information, but I'm still unclear of the procedure to update firmware using micro SDHC card. I have seen the flash_kernel example in controlSUITE.

Is it required to program flash with the bootloader program or is the bootloader program present in ROM?
I want to update firmware without using the OTP values.

By transferring the TI .hex file in micro SDHC card what should be done after that?

Is there any document that provides information of the firmware update (with and without JTAG) and an example code for the same?

Please help and guide me.

I have updated firmware using CCS Uniflash in F28069, but I'm now trying for micro SDHC card.

Sorry for the EEPROM programming question, I want to implement firmware upgradation using micro SDHC, as I was unable to do so, I asked about EEPROM, I had seen EEPROM being mentioned in the SPI_BOOT file of boot_rom example.
