Additionaly system can hang after executing ps command (there is no output). It seems that it happen only on the imxrt117x target and the imxrt106x is not affected.

FYI: Probably the source of problems is toolchain. Just cloned the phoenix-rtos-project sha:e1224d, manually build toolchains (I keep an archive), here's the quick track:

  • Using toolchain build on 24.09.2021 (sha:d275ff) this does not occur see the attached picocom logs 20230112_230433_ttyACM0.log
  • When used (my current) toolchain build on 18.11.2022 (sha:efdff3) above mentioned failure occurs to me as well.

Hopefully this helped.

can we confirm if this still happens?

I think since the issue detection there were some changes to TLS handling on Cortex-M targets in libphoenix but I'm not sure.

Seems to be fine now, tested using 8970699c419155287f806f14d5ff7166df4a0d7f phrtosproject version.

So, can we remove this:

The issue is still present, there is no info about exception but consecutive:

sysexec psh
exit
sysexec psh
exit 
sysexec psh
exit

would hang on sysexec psh at some point along the way

The above behavior is present after applying this PR https://github.com/phoenix-rtos/phoenix-rtos-project/pull/836 (probably indirectly - changes are not suspicious, only the order of symbols in .text section has been changed), the previous phrtos-project update (d358a307f8248a31904982fdac34febe7e41cad9) seems to work fine and this issue is not present.

Could you put exception log?

Could you put exception log?

Sorry, I've checked it on the older version of toolchain, I am still testing it to be 100% sure, but an issue seems to be resolved

damianloew avatar Jun 10 '24 12:06 damianloew

The issue no longer occur, checked on ea760a2fdc7ebb328303851bb29f086b3f4775c0

Probably fixed in https://github.com/phoenix-rtos/phoenix-rtos-build/commit/072b8599ebcf4178d0094d3ae256dd4e2eddba0c (toolchain rebuild needed)
