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). The link above contains a log.
