Zephyr CI runs the TF-M regressions tests as part of the TF-M integrations. We notice that the regression tests are hanging when running on QEMU for mps2_an521.
It seems the same issue is present upstream TF-M.
To reproduce:
Follow the instructions in the comment that is present here: https://github.com/zephyrproject-rtos/zephyr/pull/36954. Reproduce this with upstream TFM.
We have tested both qemu 5.1.0 and 6.0.0 and hanging is observed with both qemu versions.
Hanging occurs on NS regression tests (PS suites)
