Other Parts Discussed in Thread: SK-AM62A-LP
Tool/software:
Dear Team,
We have designed a custom board based on the SK-AM62A-LP reference design. During the hardware bring-up phase, our SPL hangs after displaying "SPL initial stack usage: 17064 bytes." We have followed the AM62Ax bring-up tips and validated the power rail, which appears to be functioning correctly.
There are no changes to the DDR part number, and the layout and routing are very similar to the SK-AM62A-LP. We added "#define DEBUG" in k3_ddrss.c and reviewed the log, finding no issues with the DDR probe and DDR initialization.
Could you please help us resolve the DDR issue?
