Use FFAT instead of SD.

[huangzngd]

Hi，schreibfaul I like your project very much! I plan to replace the SD card with FFAT, then modify the content of FFAT using a web interface, or upload a new CSV file to FFAT using the FTP function. I have modified some of the code, but when I run it, I receive the following error: I have already uploaded the data file to the flash FFAT. The modified main function is as follows. Could you please help me identify where the issue might be? I suspect that after changing the SD path to FFAT, some parameters in the path are not correctly set. thanks you!
