Hi Simon,

even with CONFIG_BOOTSTAGE disabled I still get this data abort:

Starting kernel ...

resetting ...

How can I debug this any further?

OK so it is not related to bootstage. Perhaps Linux is crashing due to something being in the wrong place?

I suggest copying some STM32 people here. You might be able to add a 'console=' or 'earlycon=' line to get a log from Linux.

Hi Simon,

it's an STM32MP1, here's a bdinfo and the full boot log. Btw, OPTEE OS is active:

Hi,

I changed from v2020.10 to v2022.10 and suddenly I get a bunch of "Bootstage space exhasuted" messages during bootm.

reloc pc : [<c01018ba>] is memcpy()

It evens triggers a reset. Older version works just fine:

 Sign value:   unavailable
 Timestamp:    unavailable

Do you know which board it is? It would help to produce a full console trace.

If you disabled CONFIG_BOOTSTAGE does the problem go away? Running out of space should not cause any problems. Also, try disabling CONFIG_BOOTSTAGE and see if that makes a difference.

You can enable CONFIG_BOOTSTAGE_REPORT to see a report before the kernel boots.
