Hey, just received a Disting mk4 that came with firmware version 4.7.
I upgraded the firmware to v4.8.1, and was no longer able to play samples from the SD card. I got the “not FAT” message on the display. The SD card is FAT32 formatted and the samples on the card previously worked with v4.7.
It’s an 8GB MicroSD formatted on Linux using dosfstools (‘mkfs.fat’).
I tried version 4.8, but still the same issue. Reverting back to v4.7 seems to work for now. The changelog mentioned the SD card code being refactored, so thought I’d post and see if anyone else is having the same issue.
