Run the install.sh script

sudo ./install.sh

Note: this git repo includes a binary for mphidflash built for x64 linux installations but it's not put on the path by the install.sh. It's there if you need it though.

Connect a jumper to the FWUP header (just above the left-most seven-segment). Power up the board and it should show up as a HID device (the Microchip HID bootloader).

$ lsusb
...
Bus 001 Device 052: ID 04d8:003c Microchip Technology, Inc.
...

Verify mphidflash can find the device:

$ mphidflash
USB HID device found: 12288 bytes free
Device family: PIC18

Use mphidflash to flash the new code:

$ mphidflash -w numato-mimasv2-pic-firmware.production.hex -r

Remove the jumper and power-cycle the board.

This install.sh script installs everything you need including putting the programmer on the path, and can be run from the command line as follows:

mimasv2-prog --filename mydesign.bin

(NB: Mimas-V2 requires the .bin file, not the .bit file)

See the original project for flashing the FPGA with screen or minicom.
