Hello, is there advice anywhere on how to make sure my board is compatible with openFPGALoader? Specifically, I'm using an ECP5 part, and I'd like to be able to program it out-of-the-box with openFPGALoader.
<PeterSchmidtNiel>
Right now I've got an FT2232 hooked up to the W25Q128 via SPI, but I'm not sure if that's what openFPGALoader expects -- maybe it expects FTDI to JTAG?
<PeterSchmidtNiel>
Or, maybe more specifically, what's the usual expectation? That you talk over JTAG to the FPGA, and then it talks SPI to the flash EEPROM, and reflashes it for you? I'm honestly not sure how these things are set up.

for ECP5 flash is usually connected to FPGA's SPI interface.
<trabucayre>
with ECP5 it's possible to access Flash through JTAG

but it's also possible to directly access, using FTDI, the flash (but never tested with EPC5)
