Thanks to the author of the previous post. It's good when the administration answers. Nevertheless, I would like to write about app review service where you can order an excellent service, as well as find a lot of useful things about the mobile industry in their blog. I know from personal experience, because I used both.

Hi Bernd,

Can you please post your code so we can decipher where you need to update the API calls to the FATFileSystem? Here's also the latest documentation for FATFileSystem on Mbed OS 5: https://os.mbed.com/docs/latest/apis/fatfilesystem.html

And here's information on how to migrate an Mbed OS 2 project to Mbed OS 5 (if your project is currently using Mbed OS 2): https://os.mbed.com/docs/latest/tutorials/migrating-to-mbed-os-5.html

Thanks!
