I've tried to format multiple SD cards in FAT and keep getting the following error [1] when flashing TELELOGGER on a ONE+ using espressif 2.03 [2]


[1] [ 11835][E][sd_diskio.cpp:802] sdcard_mount(): f_mount failed: (13) There is no valid FAT volume
NO SD CARD

It only worked for me with a 32gb card or smaller

How did you format it? I tried with multiple card but to no avail, include smaller than 32g

I assume you are using windows for the main OS? I use RMPrepUSB to CLEAN flash drive (clean button in the right down corner). and then use a windows file manager(or Disk Management) to create exFAT or fat32. Save remove and put it into Freematics. Normally works.
