The first packaged release of foboot targeting the ECP5.
This bootloader needs to be loaded onto the board using an external programmer.
Once loaded they operate in the following way:
- Hold button while powering up the board to activate
- Board will show up as a standard DFU device
- Use dfu-util to load either ECP5 bitstreams or RISCV (rv32im) code into FLASH starting at address
0x80000
Included are the binaries for the OrangeCrab board.
