Chopin is a host board that when paired with a Sechzig compute module can function as a development board.
This repo contains schematics, PCB layouts, pinouts and documentation.
Find more information on the Chopin product page.
Chopin requires a Sechzig module to function. When inserting a Sechzig module, make sure that pin 2 on Chopin and pin 2 on the module are both on the same side.
Chopin has a JTAG header that when paired with a JTAG programmer, can be used to program Sechzig modules. The following examples assume you're using a USB Blaster JTAG programmer.
Program the configuration SRAM of a Sechzig module:
sudo openFPGALoader -c usb-blaster image.bit
Program the configuration flash on a Sechzig module:
sudo openFPGALoader -f -c usb-blaster image.bit
The 3.3V JTAG header can be used to program the Sechzig module. It can also be used to provide power (5V) to the board.
