Part Number: AM3358
I made a custom board using am3358.
I'm trying to port u-boot but failed.
what should I check in my case?
I alreay tune DDR3. but not yet ported PMIC driver(TPS65217C)
Please help me!
I have the following symptoms:
1) Randomly stopped when trying to boot mmc1(sd card) # not happen on beaglebone black board
2) Invalid partition type(mmc1) # not happen on beaglebone black board
3) The variables do not work properly after call dcache_disable(); # not happen on beaglebone black board
This is my log and codes:
