TMS320C6678: Boot from the nor flash failed, how to check?

jacky lin

Part Number: TMS320C6678

Hello engineer!

We have referred to https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1073147/faq-tms320c6678-how-to-flash-the-ibl-intermediate-boot-loader-into-eeprom-and-how-to-flash-the-application-binary-into-nor-how-to-boot-the-ibl-application-binary

I found that both IBL and nor flash display program successfully, but still cannot be successfully started.

The IBL used is in C:\ti\pdk_c667x_2_0_16\packages\ti\boot\ibl\src\make\bin, install the PDK that comes with it.

Using an oscilloscope test, it was found that I2C clk had a relatively long signal duration during power on, and the clk of SPI nor flash only appeared for a few us.

Is there any other way to further confirm the problem?

Thanks!

Hi Jacky,

Due to a holiday in India, half of our team is currently out of office. Please expect a 1~2 day delay in responses.

Apologies for the delay, and thank you for you patience.

Regards,
Takuma

Jacky,

Is it the custom hardware board or the C6678 EVM of TI?

Thanks reply!

The hardware is modified from the EVM，most important parts have not been modified，the bootmode we just use a 5bit switch, but I used the resistances to follow the EVM mode. The attachment is our schematic diagram. And use this hardware to emulate is normal.

Jacky,

Let us go step by step

As a first step, after flashing the IBL into EEPROM, the IBL boots ? ---- > In this step, the flashing of IBL binary into EEPROM memory happens through I2C.

Able to see the IBL boot logs as I have given in the FAQ?

----

If yes, post me the IBL boot logs.

If no, IBL source code has to be modified according to the hardware modification.

Regards

Thanks Shankari,

I think you are right, I debugged the serial port again and confirmed that the IBL boot did not print any logs. So the i2crom_0x51_c6678_le.bin is error(which comes directly with PDK, as attached ).

i2crom_0x51_c6678_le.rar

I tried to compile IBL and found the following error:

Can you share an i2crom file that can run normally on EVM?

Thanks!

TI__Mastermind 25535 points

Hi,

The standard i2crom file which comes along the package will work only on TI C6678 EVMs.

And not on custom boards.

To make it work, the IBL source code has to be modified according to the custom board.

Path of IBL : - \ti\pdk_c667x_2_0_16\packages\ti\boot\ibl

Hi, Shankari:

So I think I have to compile IBL first, I change the Generation Tool from 8.3.2 to 7.4.24, to follow the FAQ: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1048640/faq-processor-sdk-c665x-ibl-build-steps-on-windows-10-processor-family-c665x/3879673?tisearch=e2e-sitesearch&keymatch=rajarajan%2525252520faq#3879673

And there is a error:

gcc -O2 -DEVM=c6678l -DI2C_MAP_ADDR=0x500 ./obj/iblConfig.obj ./obj/device.obj -o iblConfig.out
./obj/iblConfig.obj: file not recognized: File format not recognized
collect2.exe: error: ld returned 1 exit status

How do I handle this? Thank you!

The complete log, and setupenvMsys.sh is as follows:
