DISCO_L475VG_IOT01 mbed assertation failed

Hello guys,

Has anyone experienced this issue when running the pelion example on the DISCO_L475VG_IOT0 board ?

Connecting to the network using Wifi…
Unable to connect to network. Retrying…
Connected to the network successfully. IP address:
Initializing Pelion Device Management Client…
mbed assertation failed: block < lfs->cfg->block_count, file: /extras/mbed-os.lib/features/storage/filesystem/littlefs/littlefs▒▒ t▒


This looks like a corrupt file system. If you format the storage layer it should pass again… Could it be that you previously formatted the file system as FAT?


Should do the trick.

We do it like this.

Thank you Jan.
It worked perfectly.
