Sadly it seems the USB-C PoE adapters I have are borked in some way (they supply power but block ethernet link) but I have some higher quality ones arriving tomorrow. [2026-03-08 11:36 p.m.] mithro_ @carlfk - Did you see that behaviour like that with those adapters at all? [2026-03-08 11:37 p.m.] carlfk maybe? [2026-03-08 11:37 p.m.] mithro_ I decided to buy a whole bunch of these adapters -> https://www.waveshare.com/poe-splitter-type-c.htm {Embed} https://www.waveshare.com/poe-splitter-type-c.htm Industrial Gigabit PoE Splitter, Metal Case Protection, 5V 2.5A Typ...

[2026-03-14 9:53 p.m.] carlfk you can install a few things into ramdisk - but that gets anoying after a bit [2026-03-14 9:53 p.m.] mithro_ @carlfk - At some point we should chat about how we want to proceed with the current pici repo. [2026-03-14 9:53 p.m.] carlfk yup - I think I opened an issue about how to .. um.. spemthing about the TT boards [2026-03-14 9:54 p.m.] mithro_ https://github.com/fpgas-online/todo/issues {Embed} https://github.com/fpgas-online/todo/issues fpgas-online/todo TODO items for https://fpgas.online.

[2026-03-14 9:58 p.m.] carlfk if I run it on the pi, will it report what port it is hooked to? [2026-03-14 9:59 p.m.] mithro_ @carlfk - Actually yes, it goes both directions [2026-03-14 9:59 p.m.] carlfk neat [2026-03-14 10:06 p.m.] mithro_ @carlfk - BTW Did the Acorn + compute boards ever get deployed? [2026-03-14 10:34 p.m.] carlfk were those the 4 things in a 1U box? [2026-03-14 10:45 p.m.] mithro_ Yeah [2026-03-14 10:46 p.m.] carlfk yes. they are hooked to the same PoE swtich at the pi/arty [2026-03-14 10:46 p.m.] carlfk not sure what ports. might be a way to figure it out looking at the switch's UI [2026-03-15 1:08 a.m.] wspitts2 If you guys are still having trouble with openocd running on RPI we got it working to our jtag taps (which are standard) as well as to ibex and I can share the instructions for our pi zero wireless ones. [2026-03-15 1:10 a.m.] wspitts2 We also extended openocd to handle daisy chained JTAG taps. I have to look back at our notes from last year. [2026-03-15 1:20 a.m.] wspitts2 This allows you to connect any number of JTAG taps together in the design. The openocd driver as it sat last year didn't allow this (at least as we had tried) but the JTAG standard does. It is nice when you have a multimodule hardware design with multiple design specific taps and want to put some in bypass and interrogate the isolated one.
