Hi Ti,
Our EE engineering met an issue that AM6548 boot fail when during test with -20 degree C with our customized board.
Below is the fail log. The fail rate is about 25%.
We want to know:
1.Where the EL3 is? In the SPL or uboot or?
2.What's the possible reason to cause this exception happened?
U-Boot SPL 2020.01 (Sep 06 2021 - 13:47:59 +0800)
SYSFW ABI: 3.1 (firmware rev 0x0015 '21.1.1--v2021.01a (Terrific Lla')
Reading on-board EEPROM at 0x50 failed 1
Trying to boot from MMC1
