i have made my own custom board based on beaglebone black wireless.
only change in that is my EEPROM is blank. To bypass that check i tried following methods.

  1. i applied these patches based on this post

https://octavosystems.com/forums/topic/osd3358-boot/#post-4733

– patch -p1 < 0001-am335x_evm-uEnv.txt-bootz-n-fixes.patch
– patch -p1 < 0002-U-Boot-BeagleBone-Cape-Manager.patch
– patch -p1 < 0002-NFM-Production-eeprom-assume-device-is-BeagleBone-Bl.patch

it didnt give any result and i havent received anything on serial debug header.

  1. then hardcoded the function in u-boot/board/ti/am335x/board.h

static inline int board_is_bone_lt(void)
{
printf(“called it\n”);
return 1;
}

i received following log on the serial debug…
