<somlo> might be another while until it shows up in the official tree, but at this point it's just a matter of waiting :)
<_florent_> somlo: Great work! Thanks
<_florent_> (somlo: Still need to test LiteSATA on NexysVideo, will do before leaving the office...)

<somlo> _florent_: do you happen to know, should there be a direct contact between the dp0_[c2m|m2c]_[p|n] fpga pins connected to the LPC/FMC connector and the sata [a|b][+|-] (tx/rx pairs)? Or is there usually a capacitor connected inline?
<somlo> I've been thinking of taking an ohm-meter to see if my extension card connects the right fmc pins to the right sata pins, but that may not be conclusive if it's not supposed to be a direct electric contact :)
<somlo> and I noticed some sort of inline components soldered on the adapter card close to the SATA pin leads :)
<somlo> I'm very much a beginner when it comes to proper electrical engineering :)
<somlo> ... and I've convinced myself that the fpga-to-fmc pins are correct here: https://github.com/litex-hub/litex-boards/blob/master/litex_boards/platforms/digilent_nexys_video.py#L184
<somlo> so it's a matter of whether I have a broken fmc-2-sata adapter, because the wiring clues all seem to check out and be correct
<somlo> _florent_: there *does* appear to be a 100nF capacitor inline between the FMC connector and whatever's on the other side (sata pins) in the schematic on page2 of http://mirror.ini.cmu.edu/litex/HTG-FMC-X4SFP-X4SATA.pdf
<somlo> so my ohm-meter plan to check for connectivity is likely not going to work :D
<tcal> In a build of mine that /uses/ LiteX, I'm hitting a typo in the meson.build file for picolibc/data: `pythondata_software_picolibc/data/meson.build:737:10: ERROR: configuration_data.set got unknown keyword arguments "descrption"` (this typo actually occurs twice). But for some reason I don't get an error when doing a pure LiteX build, even though the typo is there as well. SOLUTION: I was using the lastest `meson` from its
<tcal> repo (the pure LiteX build was using meson via pip3). When I backed off to the 0.61.1 tag, it worked again. I've opened an issue for picolibc.

<Johnsel> hello everyone
<somlo> _florent_: hmm, the antmicro fmc adapter schematics show 10nF capacitors (as opposed to the 100nF ones used on the HTG adapter) -- wonder what that means for the target operating SATA frequency being supported...

<Johnsel> Error (170012): Fitter requires 988 LABs to implement the design, but the device contains only 963 LABs
<Johnsel> I am trying to run linux-on-litex on an Arduino MKR Vidor 4000
<Johnsel> which is an altera cyclone 10 LP device
<Johnsel> any ideas where/how to optimize?
<Johnsel> platform/target are already minimal (1 clock, sdram and serial only)
<Johnsel> halving L2 seemed to have done the trick
