Hello Cedric, 

I tried the FWU tests on musca b1 platform and all of them passes without any failures.  

Could you please provide more context on specific version/commit or platform where you encounter PSA_ERROR_STORAGE_FAILURE?

Best Regards,

Maulik

Hi,

I encounter a storage failure when trying to reject a staged image. I get this error by executing `tfm_fwu_test_common_001` in `fwu_tests_common.c`. The error occurs when the `erase_boot_magic` function attempts to erase the magic number in the image trailer by writing erase into it.

The reason I am writing this post is to ask:

1. If the `erase_boot_magic` failure is a known bug in the firmware update, is a fix planned or existing?
2. Why doesn't the `erase_boot_magic` function erase the sector where the magic number is located in the image trailer, considering we erasing in a flash?

Thanks!

Best regards, 
Cedric
