Here is an attempt to use the Pokitto SD card by plugging in the Pokitto and it detecting as mass storage device.
It doesn’t seem to work properly yet. Perhaps it can be adapted to use the existing Pokitto SD
– UPDATE –
After reformatting my SD card to FAT32 following a hint on discord by @jonne about why a different project might not be behaving correctly, this seems to work quite well, not much in the way of slowness etc.
Still use at own risk, but I believe the risk is low.
