Hi Bin.

You can use 'sf test' as well. That fails for me at present.

I did notice that a while back but then forgot about it. I'm not yet
running tests automatically on boards (although my lab is coming
along) and I don't think there even is a test for persistent
environment.

If I recall, the problem started with the conversion to spi_mem. But
at least for me, the MRC writing works.

Regards.
