c6678 rebuilt ibl doesn't work

Sungyeol Park

Hi, I'm trying to modify IBL code for my custom board.

But, the origin ibl code from mcsdk_02_01_02_06 doesn't work in EVM board.

When using program_evm\binaries\evm6678l\eeprom51.bin works well, but rebuilt out file (origin source code, never modified) compiled by minGW doesn't.

Also, when write to EEPROM using EEPROM writer, eeprom51.bin is written 52072 bytes, but rebuilt IBL code takes 52108 bytes.

There wasn't any errors compiling by minGW.

I followed all of instructions in ibl\doc\build_instructions.txt for c6678.

Should I have to change setting for compile? Or have to modify code?

I tried .bin file, and I found it works well. .out file still doesn't work.

So, I'll try to write .bin file to EEPROM.

Thanks.

Hi,

Have you tried rebuilding with CCS, as stated in the the user guide: processors.wiki.ti.com/.../BIOS_MCSDK_2.0_Getting_Started_Guide

Also check if the compiler used by minGW is THE SAME AS the one used by CCS.

Best Regards,

Hi Yordan, thanks for your answer.

I didn't know that IBL can be compiled by CCS, so I just used MinGW only.

I'll try it by CCS right now, thanks.

Hi,

Refer just to the compiler used, as suggested in this thread: e2e.ti.com/.../177420

Also check the following threads:
e2e.ti.com/.../223607
e2e.ti.com/.../233684
they target issue similar to yours.

Best Regards,
Yordan

Thank you for your update. You should use .bin for testing.

Please refer c66xx keystone bootloader user guide for i2c boot image specification. Thank you.
