Looks like it’s linking tfm_hal_platform_init() from platform/ext/common/tfm_platform.c rather than from platform/ext/target/cypress/psoc64/tfm_hal_platform.c.

The current version breaks console output for the secure partition on psoc64 with IAR or ARMCLANG. Appears to work with GNUARM.

It appears that this commit is the culprit: fce78aef Platform: Duplicate the tfm_hal_platform_init

The console starts out good, then during tests only garbage is seen.

Linker script issues?

Hi Thomas, Chris,

I think it is the linking issue.

Not sure why.

The last code base should have no this issue as this patch https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/11407/12/platform/ext/common/tfm_platform.c#b13 (merged) has removed the common tfm_hal_platform_init().

Could you rebase to the latest code?

Best Regards,

Kevin
