AM6442: u-boot hangs in mmu_setup

Artur Toews

Part Number: AM6442

Hi,

my boot process stucks in mmu_setup()->set_sctlr(get_sctlr() | CR_M).
I'm using SDK 11.02.08.02 and have read this post:
AM62L: Stuck while enabling mmu. - Processors forum - Processors - TI E2E support forums

Our custom board has 1G ram. Is there still an open issue in this version? - Or what might I have done wrong.

BTW: My board already runs fine with u-boot 2021.01. But I'm not able to get it running with u-boot 2025.01.

Hi Artur,

Does the UART console print any message before boot gets stuck? If so, please attach the log.

Hi Liu,

I found the issue already.
For any reason I the memory config in the dts was wrong.

reg = <0x00000000 0x40000000 0x00000000 0x40000000>;

instead of

reg = <0x00000000 0x80000000 0x00000000 0x40000000>;
