cr1901_modernhttps://twitter.com/cr1901/status/1073368943673442305 I know ppl have had issues compiling yosys on -j 4 on RPi 3 in the past.00:18
cr1901_modernI've done it successfully a few times before, but tonight for some reason it wouldn't cooperate00:18
cr1901_modernTurns out on these SBCs, the power cable quality matters00:18
cr1901_modernor "I only swapped the power cable and now yosys is building correctly"00:19
ZipCPUOuch!00:28
ZipCPUI wonder if -j2 would work better ?00:28
cr1901_modern-j1 worked fine, -j3 also worked but I could tell that it was close to rebooting00:29

ZipCPU"could tell that it was close to rebooting" ??  What does that look like?00:30
cr1901_modernI redid the build w/ -j 4 immediately after and instead of making it to 17% it made it to 2% :)00:30
ZipCPULol00:31
ZipCPUOk, I got it now00:31
ZipCPUWhat would you recommend based upon this experience?00:31
cr1901_modern"If yosys doesn't build on your RPi or SBC clone, not only make sure that the CPU is overheating, but try different power cables"00:32
ZipCPU:D00:33
ZipCPUDo you use yosys on your RPi often?00:33
cr1901_modernTinkerboard comes w/ a heat sink; I ran tests when it was new, and I never got it to crash even w/ make -j 4 on yosys/openocd etc00:33
ZipCPUBetter power supply?  Bigger capacitors?00:33
cr1901_modernOnce a month? Mostly sits there lol00:33
ZipCPUI tried yosys with my RPi.  I was disappointed in how long it took to build a design, and so ... decided to keep using my desktop00:34
cr1901_modernMy official RPi is a Model A- 256MB RAM- from the end of 201300:35
cr1901_modernit runs NetBSD, and it's not possible to compile yosys on it; not enough RAM00:35
cr1901_moderneven w/ -j1... gmake just refuses to do it00:35
qu1j0t3thx for making me feel old00:35
cr1901_modernhttps://twitter.com/cr1901/status/1073371611670212608 Aaaanyways, I'm gonna have to reinstall00:37
cr1901_modernWhich I would've had to do anyway eventually, but... good time as any00:37
