Take a look at: viewtopic.php?f=18&t=1901Yes, that precisely the case. Spiffs raw (so without vfs) works fine.
As soon as I use the vfs part (I used the code at https://github.com/nkolban/esp32-snippe ... vfs/spiffs)m I can not read the file back (I can not see if it is written in the first place).
Best,
