| cr1901_modern | https://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_modern | I've done it successfully a few times before, but tonight for some reason it wouldn't cooperate | 00:18 |
| cr1901_modern | Turns out on these SBCs, the power cable quality matters | 00:18 |
| cr1901_modern | or "I only swapped the power cable and now yosys is building correctly" | 00:19 |
| ZipCPU | Ouch! | 00:28 |
| ZipCPU | I 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 rebooting | 00:29 |
| *** tecepe1 has quit IRC | 00:30 | |
| ZipCPU | "could tell that it was close to rebooting" ?? What does that look like? | 00:30 |
| cr1901_modern | I redid the build w/ -j 4 immediately after and instead of making it to 17% it made it to 2% :) | 00:30 |
| ZipCPU | Lol | 00:31 |
| ZipCPU | Ok, I got it now | 00:31 |
| ZipCPU | What 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 | :D | 00:33 |
| ZipCPU | Do you use yosys on your RPi often? | 00:33 |
| cr1901_modern | Tinkerboard 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 etc | 00:33 |
| ZipCPU | Better power supply? Bigger capacitors? | 00:33 |
| cr1901_modern | Once a month? Mostly sits there lol | 00:33 |
| ZipCPU | I tried yosys with my RPi. I was disappointed in how long it took to build a design, and so ... decided to keep using my desktop | 00:34 |
| cr1901_modern | My official RPi is a Model A- 256MB RAM- from the end of 2013 | 00:35 |
| cr1901_modern | it runs NetBSD, and it's not possible to compile yosys on it; not enough RAM | 00:35 |
| cr1901_modern | even w/ -j1... gmake just refuses to do it | 00:35 |
| qu1j0t3 | thx for making me feel old | 00:35 |
| cr1901_modern | https://twitter.com/cr1901/status/1073371611670212608 Aaaanyways, I'm gonna have to reinstall | 00:37 |
| cr1901_modern | Which I would've had to do anyway eventually, but... good time as any | 00:37 |
