ESP-Prog to Altera adapter

Lets you use a $10 ESP-Prog programmer as the equivalent of an Altera USB Blaster.

The FT2232HL on the ESP-Prog supports JTAG/MPSSE, which means you can use it to flash an FPGA using openFPGALoader.

This board can be ordered assembled from JLCPCB using the gerbers and BOM included in the release/ directory. Or you can hand solder it, obviously.

Update

It works. Tested with Waveshare CoreEP4CE6.

openFPGALoader -c ft2232 --fpga-part ep4ce622 -f [binary].rbf
