RK3576 stuck at INFO: BL31: Initializing BL32

[cu6apum]

Hi there!!! LTNS.

 

Not pretending to ask for a solution. Just curious, what am I doing wrong, after a decade with Armbian. ;) 

A new Chinese board with RK3567, quite similar to kickPi. Boots up to "INFO:    BL31: Initializing BL32" then hangs. Changing DTB in armbianEnv.txt does nothing, same is for verbosity.

I guess there's some pre-DTB in uboot, as I recall, this is common with RK chips. And it seems to not match my hardware. Any reasonable way to fix, before i rebuild the whole image?

 

Thanks in advance!

Hi cu6apum,

You already guessed right about the pre-DTB — armbianEnv.txt can't touch this stage. And since BL31 printed at all, DDR init in TPL/SPL succeeded,
so it's the trust chain that's dying.On RK3576 that line usually means one of two things:

1. The trust image on flash has no OP-TEE payload (some vendor SDK builds are TEE-disabled), or one built for a different DRAM map — BL31 jumps,
nothing answers, silence.

2. BL31 and BL32 aren't from the same rkbin build — happens when a vendor flash and an Armbian image each rewrote part of the chain.

 

Maskrom + rkdeveloptool to dump what's actually on flash, then rewrite idbloader + uboot + trust as a matched set from the closest supported
RK3576 board. If it turns out TEE-less, a no-TEE trust combo is a legitimate workaround — you lose the secure boot path but gain a booting
board. Happy to compare notes if you post the full UART log.

Thank you! Yes, I abandoned the secure boot, don't need it. Built uboot from other distro (linux-rk from RK itself) and am able to boot.
