You need to flash the loader menu from extFlashLoader examples first, then copy the unzipped /apps into SD /apps!
Press/hold the KEY_A and reset the WioTerminal, the SD-Loader menu should start...
(Works with WioTerminal(SAMD51+ILI9341))
Use bin2uf2.py (from Microsoft open source) to convert SDMENU firmware.bin to sdmenu.uf2 , drag and drop to UF2 bootloader!
SAMD51 Memory Map
The memory map for different NVM...
Zipped apps
The zipped apps binary for the following projects! Unzip this and place /apps into SD /apps
