Hi Thomas,

It seems to be related to the startup assembly code. It was reported by Alamy.

Dual-cpu NS mailbox relies on some RTOS modules, which shall be initialized after RTX kernel starts. Armclang and GNUARM startup assembly code already calls kernel start function. Therefore the ordering of NS mailbox init and RTX kernel init doesn’t matter.

I guess IAR startup code doesn’t call the additional kernel start function.

This change has already included by the tf-m-tests version specified in TF-M configuration. Could you please update your TF-M version a bit?

Best regards,

Hu Ziji

Hi David,

It fixed a runtime problem with psoc64 when building with IAR.

I don’t understand why ARMCLANG and GNUARM builds seems to have been unaffected.

Cheers,

Thomas

For some reason it seems that IAR is the only toolchain affected by:
https://git.trustedfirmware.org/TF-M/tf-m-tests.git/commit/app/main_ns.c?id=4ae00fe

Can we please update update the version to at least 4ae00fe?

Cheers,
Thomas
