There’s been a small update to the Jaguar SD cart project – It looks like the developer is finishing the firmware update code, which is a good sign that this long-awaited flash/rom cart project may finally be finishing up! No pre-orders have opened yet, but I’ll have a post here showing when it does!
Got stuck back into the #JaguarSD today! I've split the firmware into a bootloader and main firmware. The bootloader checks for an update file on the SD card and executes the main firmware if its not there. Now to write the micro self-updater and ASIC bitstream update code… 😀

I've got the #JaguarSD firmware updating successfully from SD card now. First time I've written a self-updating microcontroller bootloader (I've not needed one before), but pretty straight forward. It should be un-brickable, which is nice! Next updating the ASIC bitstream too…
