slagernateperhaps my radiant isn't working is bc I'm running Ubuntu 22.04. It ran a few times but now it seems broken when using the blinky.v and blinky.pdc from the example in pjroxide: `@E| Mal-formed command line - please check for extra ` `quotes in macro specification'. Has anyone tried radiant on Ubuntu 22.04? Even the gui is whacked. Maybe I should01:53
slagernaterevert to a previous OS / use a docker / VM.01:53

tpw_rulesi failed many moons ago and on a completely different platform, but even today i still cannot get litex_term to upload a file over jtag19:35
tpw_rulessafe mode does not help. it just says unexpected response from device: 'b'E''19:36
tpw_rulesthe bios works great and the memory test passes19:37
tpw_rulesi can type stuff in and run commands fine19:38
cr1901You're not going to like this response, but I'm pretty sure I've seen this error before and I forget the solution19:39
tpw_rulesthe file is only a few kilobytes. even uploading a 3 byte file does not work19:39
tpw_rulesi'm just ranting to build energy to dig into the code19:40
tpw_rulesso the E means timeout which means either the value is too short or the timer is broken19:43
tpw_rulespatched the timeout out of the bios and the upload runs at a breathtaking 74 bytes per second20:58
tpw_rulesnot sure why. reading back from the jtag port seems to go quite quickly20:59
tpw_ruleslike the donut demo is clearly cpu limited, not waiting for characters to be received21:00
tpw_rulesthe protocol is symmetric, this makes no sense. is it an interrupt problem or something?21:16
tpw_rulesok cool, some minor tweaks to the tcl and now we're above 1000 bytes per second21:55
tpw_rules(wow that is a cursed language)21:55

tpw_rulescr1901: just filed a PR to fix this properly, do you still have a setup which uses jtag_uart?23:24
cr1901No, not on me, I'm afraid :/23:33
