It may actually not be a corruption of the filesystem but some
timing issue on the mount procedure. To test that we could disable
the auto formatting on mount failures.<br class="">
<br class="">
The issue may also be dependant on the hardware version, i.e. it
could be caused by the bug that caused the SD speed issue on the
first 3.1 batch.<br class="">
<br class="">
I only have tried the idf update on my batch 1 module (my bench /
development module). I think most of our edge testers also have that
version.<br class="">
