| npcomp | _florent_ dkozel Hi! Very new to the community here, I have had a latent interest in FPGA for some time, but was always previously deterred by form factor or price. | 19:05 |
| npcomp | I saw your tweet/discussion on the CLE 215 from SQRL, and along with finding some other resources online, decided to spring for one. | 19:06 |
| npcomp | Excited to potentially joing the party, but looks like I still need to locate my JTAG adapter? | 19:13 |
| *** Skip has quit IRC | 20:15 | |
| _florent_ | npcomp: Hi and welcome, the CLE 215 is indeed a nice FPGA board. For now you will need a JTAG adapter, it would be possible to reverse engineer the gateware update protocol over PCIe, but not sure it's worth doing it since JTAG pins are available and documented. | 20:36 |
| CarlFK | xobs: (or _florent_) can/is the gpio stuff on the pi standard jtag that could be used with just some jumper wires? | 20:43 |
| awordnot | for my CLE 215 I just ended up buying the mating connector and some precrimped wires from digikey, then I cut them in half and soldered the other end to a standard 2.54mm header | 20:49 |
| awordnot | I'm using the digilent HS3 jtag adapter which supports vivado, but if you were using OpenOCD I think you could use anything | 20:50 |
| zyp | I did the same, planning to use a generic ft232h adapter | 20:51 |
| zyp | … if my CLE 215 ever arrives, it's been stuck in the mail for weeks now | 20:51 |

| npcomp | I think the easiest OpenOCD-compatible board might be a bus pirate I have close at hand, but to be honest I haven't really done much with openocd | 22:59 |
| npcomp | > it would be possible to reverse engineer the gateware update protocol over PCIe | 23:01 |
| npcomp | I was wondering if there was a good place to document stock gateware on the board, and continuing work that might take place on it. | 23:04 |
| npcomp | I was thinking a wiki maybe? I see https://github.com/litex-hub/litex-boards/tree/master/litex_boards/platforms | 23:07 |
| tpb | Title: litex-boards/litex_boards/platforms at master · litex-hub/litex-boards · GitHub (at github.com) | 23:07 |
| npcomp | But that doesn't seem like a place to put like, pinouts, board pics, etc. | 23:09 |
