Hi Thomas,

For your 2^nd question. I have tested it on my side and it has the same problem.

The TF-M can print normal boot message, but the log becomes garbage after enter into Arch test. The PSA Arch test is another independent project, and I have arisen this issue to the PSA Arch test project: https://github.com/ARM-software/psa-arch-tests/issues/164.

You can watch this issue directly.

Thanks,

Edison

Hi Thomas,

Thanks your mail.

For your 1st question. There is indeed a problem to build the PSA arch crypto test on the Musca_a board for the RAM size is too small. I suggest you split the crypto tests into different test images on the Musca_a board.

For the 2nd question, I only test that on FVP AN521 but never met this problem. We will test that on the MPS2 AN521 board soon to check if it is a real problem. If yes, we will try to fix that quickly.

Thanks,

Edison

Triggered by Rays mail on slow RSA key pair generation, I built and tried to run the tests, but ran into a couple of issues:

1) I attempted to build it for the Musca A, but apparently that doesn't have enough RAM to run these tests

2) Switching to an MPS2+ with AN521 configuration I see that the baud rate on the UART appears wrong when running the tests.

mcuboot produces correct messages at 115200 bps, as does the normal ConfigRegression* tests, but the ConfigPsaApiTest* appears to produce just garbage.

Is there a setting I need to set to get any useful data on the terminal when running the ConfigPsaApiTests?

Cheers,
Thomas
