Other Parts Discussed in Thread: SK-AM62A-LP, AM62P
Tool/software:
Using SDK 10.01.00.05 on the SK-AM62A-LP board, attempting to evaluate low power mode characteristics, and am encountering both of the failure modes seen in this E2E post.
I'm encountering their first error when using the pre-compiled Linux SDK binary (download) linked from the EVK product page (printk output below):
