Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : Maybe FatFS to PicoMite?

I might be wrong here, but I seem to recall reading somewhere from Peter, that he used TinyFS cos anything larger gobbles up too much of the very valuable RAM in the 2040 chip. If I am remembering that correctly, then upgrading the FS won't be something that will be happening anytime soon I would think - other then squishing any bugs found, naturally. I expect Peter and others more in the know here with the internal details then I, will comment and tell me if that is correct or I am wrong. But that is what I seem to remember.

picomite uses Full FatFS for SD and LitteFS for flash. FatFS does not support wear levelling. LittleFS does
