Dear Janna,

it appears the error you are facing is simply the lack of a mass storage hardware: For a file system, you need flash storage, which is AFAIK not available on the iotlab-m3 boards.

You should try a device that either has onboard flash or a flash card reader.

Best,
 Thomas

Hello!
I tried the filesystem example with native board. Unfortunately i cannot create a new file with "tee". I get the error message "error while trying to create file.txt". I have also compiled the example for the iotlab-m3 board. When i try to execute the "mount" and "format" commands on m3 board, i get the error "No external flash file system selected". I can't create a new file with "tee" here either. What could be the reason?
I have not made any changes to the code. What am i doing wrong?
Thanx!


Kind regards,

Janna
