Part Number: AM3358
Hello Team,
We have designed a custom board with the AM3358BZCZ100 processor. The hardware pinout and configuration for EMMC, uSD, and boot settings are the same as the BeagleBone Black. However, we have changed the DDR memory from MT41K256M16 to IS4346TR16512B.
Currently, we are attempting to boot the board from the SD card, we are able to boot till u-boot and its not loading further. attached is the log for your reference.
From u-boot we are able to read and write to DDR memory successfully.
Kindly let me know if any configuration is needed.
Thanks & Regards,
