Hi Sara,
I'm not sure SmartFS was ever tested with this particular sequence where
the volume is erase and then re-mounted to a different location. If I
get a chance this weekend, I will take a look at it since you have a
very specific test sequence.

Hi all,
I am facing some issues when enabling SMART FS and I'd like to know if
this is an expected behavior or maybe a bug on NuttX.
First issue:
- If I use the following sequence:
1. smart_initialize()
2. nx_mount()
nx_mount throws errors like: sector not allocated and no low level format.
To fix it, all I need to do is to format it by calling mksmartfs
/dev/smart0 and I can reset and have my mount point correctly mounted.
Second issue:
If I run flash_eraseall just like the following sequence it will throw an
I/O error when writing to a file in the recent created mount point.
mksmartfs /dev/smart0 mount -t smartfs /dev/smart0 /temp echo "TESTE" >
/temp/teste cat /temp/teste umount /temp flash_eraseall /dev/smart0
mksmartfs /dev/smart0 mount -t smartfs /dev/smart0 /another_temp
echo "TESTE" > /another_temp/teste
P.S:
The error happened on ESP32C3 DevKit and also on simulator.
To reproduce the error, you basically need to enable the following configs:
CONFIG_FS_SMARTFS
CONFIG_MTD_SMART
CONFIG_SYSTEM_FLASH_ERASEALL
Thanks, Sara.
