Part Number: TDA4VM
Hi TI,
I want to create an initial baseline for our custom board (using TDA4 SoC. Unfortunately, I was not able to find any instructions for J721e/TDA4. The only resource I found is the following: https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/AM335X/linux/How_to_Guides/Board_Port/U-Boot.html
I did the following steps:
- Copy files from board/ti/j721e/* into new directrory board/myComp/myBoard/*
- Removed TI_I2C_BOARD_DETECT according to previous mentioned link
- Adapted Kconfig in board/myComp/myBoard according to the previous mentioned link
- Created new defconfigs by copying the content of j721e_evm_a72_defconfig and j721e_evm_r5_defconfig into myComp_myBoard_a72_defconfig and myComp_myBoard_r5_defconfig
- Replace CONFIG_TARGET_J721E_A72_EVM in newly created *_a72_defconfig with CONFIG_TARGET_MYCOMP_MYBOARD_A72
- Replace CONFIG_TARGET_J721E_R5_EVM in newly created *_r5_defconfig with CONFIG_TARGET_MYCOMP_MYBOARD_R5
- Append every #ifdef CONFIG_TARGET_J721E_A72_EVM with #if defined(CONFIG_TARGET_J721E_A72_EVM) || defined(CONFIG_TARGET_MYCOMP_MYBOARD_A72) in U-Boot source code
- Append every #ifdef CONFIG_TARGET_J721E_R5_EVM with #if defined(CONFIG_TARGET_J721E_R5_EVM) || defined(CONFIG_TARGET_MYCOMP_MYBOARD_R5) in U-Boot source code
Doing all these steps, I should be able to build similar bootfiles like before. However, the build throws following error:

I already verified, that CONFIG_SET_DFU_ALT_INFO=y is set.
Do you have any idea on what could be missing here?
Additionally, it would be very helpful, if you could proved a general instruction on how to add custom boards to U-Boot source code for TDA4.
Thanks for your help and best regards,
Felix
