NAFScreate_volume fails with NAFS_BLOCK_SCAN_FAILED

Hi everyone,

I have an NS9215 module that stopped booting. It just blinks its LEDs.

I have traced the problem to a failure of function NAFScreate_volume. It returns error code NAFS_BLOCK_SCAN_FAILED. The description of this error in the API reference is:
“The internal block scan process failed.”

What does that mean? And what could have caused it?

Is there an existing way to dump the entire contents of flash to a file on my PC?

I am using Net+OS 7.4.2.
