Flashing/program via PCIe #17

Open dannycoin opened 3 years ago

dannycoin commented 3 years ago

Hi there..

1) can an Acorn CLE 215+ / Nitefury be flashed through PCIe without JTAG cable? 2) is it mandatory to use a JTAG cable to flash/program? 3) Is there a guide to flashing via PCIe? 4) Can I design in tools like Vivado and then flash / program via PCIe?

  1. Yes, but only if there is already a bitstream that supports this. See https://github.com/RHSResearchLLC/NiteFury-and-LiteFury/tree/master/spi-loader
  2. Only if you don't already have a compatible bitstream running
  3. See https://github.com/RHSResearchLLC/NiteFury-and-LiteFury/tree/master/spi-loader
  4. You can use Vivado to create .mcs, then load that MCS using the spi-loader

The factory 215+ bitstream probably won't work with the spi-loader (not sure). But the factory NiteFury bitstream should.

Finally, you can also use a FTDI for programming, with OpenOCD. Vivado doesn't recognize FTDI but OpenOCD does. I don't have an example for NiteFury, but here is an example for PicoEVB, which is similar: https://github.com/RHSResearchLLC/PicoEVB/tree/master/spi-flash-program-openocd

I wrote up a guide here using the above info, hopefully this can help: https://github.com/Gbps/nitefury-openocd-flashing-guide

Nice! I tried this same exact thing but it didn't seem to work, and I gave up rather quickly. Now that I think about it, I was trying on a blank flash, which probably wasn't properly configured. *Furys that have been programmed once have the flash preconfigured. Maybe I'll integrate your work with that caveat. Thanks again for this nice writeup!
