_florent_Hi, with https://github.com/enjoy-digital/litex/commit/44b223a9182318d58b9d4249d879f925dfd11e7d, the BIOS/libs will now be fully rebuilt on CPU type/variant change13:41
cr1901_florent_: Is this still possibly of any use for you? https://github.com/cr1901/libmodem/blob/master/scripts/misoc-config.py (litex-config.py)13:55

_florent_cr1901: Sorry I've still not been able to look at it, I'll try to do it soon (so can't answer for now)14:30
_florent_vomoniyi[m]: do you see you board with LitePCIe? Which design are you building?14:32
vomoniyi[m]No I don't and I'm building the litex build of the sqrl acorn target14:38
vomoniyi[m]Wait, yes I can see it in litepcie14:45

tpw_ruleshello all. i have a nitefury board i'm trying to get the litex boards example to work on20:46
tpw_rulesi installed litex and ran the "./sqrl_acorn.py --uart-name=crossover --with-pcie --build --driver --load --variant=cle-215" but vivado eventually dies with "ERROR: [Vivado 12-5201] set_clock_groups: cannot set the clock group when only one non-empty group remains."20:47
tpw_rulesvivado 2020.2 and python3.9.1 on ubuntu 20.04 is what i am using20:47

tpw_rulesdo i need an older vivado?21:10
tpw_ruleshm, 2019.2 dies with something about XML schema validation21:30
zypI've used 2019.2 before22:00
zyp(to build for cle-215)22:01
tpw_rulesthat's strange. do you recall what commits you used? the litepcie phy files only changed 11 months ago22:02
zypno, I don't, but it might be more than 11 months ago :)22:10
tpw_rulesa3f: i see you have an issue filed on litepcie where you got this working, what vivado are you using? are you using the latest version of all the litex code?22:20
tpw_rulesahhh, the problem is trying to use the crossover uart22:30
tpw_rulesbut i don't have a real uart available... what voltage are the uart pins on the board? is there a way to use one over jtag?22:30
