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 (merged) has removed the common tfm_hal_platform_init().

Could you rebase to the latest code?

Best Regards,

Kevin

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.

Caution: This e-mail originated outside Infineon Technologies. Do not click on links or open attachments unless you validate it is safe.

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?

/Thomas
