| cr1901_modern | Why does icetime take such a HUGE amount of memory now? I can't compile it on an ARM SBC with _two_ GBs of mem. | 00:05 |
|---|---|---|
| cr1901_modern | And 1GB of swap | 00:05 |
| cr1901_modern | guess that means nextpnr is also hopeless thanks to boost python being god awful w/ mem usage | 00:05 |

| qu1j0t3 | can't you cross-compile? | 00:11 |
| * qu1j0t3 may be a dumb question | 00:11 | |
| cr1901_modern | I'm not setting up a libc and all the associated prerequisites that nextpnr and icestorm depends on | 00:13 |
| cr1901_modern | That might've been fun in my early 20's (linux from scratch was fun back in the day), but I have _no_ interest in that crap now | 00:13 |
| * qu1j0t3 nods | 00:15 | |
| cr1901_modern | increasing swap to 2GB worked | 00:32 |
| swetland | having worked a bunch with vivado, my expectations for eda tools running in limited memory and compute are very low... | 00:35 |
| cr1901_modern | the point was it used to work. Hell, you could compile the tools on rpi3 (1GB RAM) | 00:35 |

| mithro | daveshah: What is the preferred way to report something which "works" in icecube2 but not in nextpnr? I haven't really had time to figure out why | 23:32 |
| daveshah | mithro: probably just create a gh issue | 23:33 |
| daveshah | Unless it's something self obvious like timing | 23:33 |
| mithro | daveshah: I *think* that it is caused by timing related stuff through the PLL -- but what is unclear to me is that nextpnr reports the clock-domain frequency is faster than the 48MHz the PLL is outputting... | 23:34 |
| daveshah | mithro: have you tried with tnt's PR? | 23:34 |
| mithro | Nope! | 23:34 |
| daveshah | That fixed a PLL bug | 23:35 |
| mithro | Has that been merged? | 23:35 |
| daveshah | That affected the tinyfpga bx board | 23:35 |
| mithro | Yeap, on the tinyfpga-bx board | 23:35 |
| daveshah | No not merged yet | 23:35 |
