satellite: SYS CLK did not switchJust tested the newly built zc706 `boot.bin` for 125 and 100 MHz separately, both booting fine, thanks!
ljstephenson commented on issue M-Labs/artiq-zynq#246
satellite: SYS CLK did not switchWe use the 100 MHz directly with `rtio_clock = ext0_bypass`, i.e. we aren't making a 125 MHz RTIO clock with PLL (I wasn't aware this was an option, although it's not one we're likely to use…

satellite: SYS CLK did not switch@sb10q I've confirmed (unsurprisingly) that this affects Kasli-SoC DRTIO masters also; the same commit introduces the breakage. This is with the external clock running at 100 MHz. Just to push…

satellite: SYS CLK did not switchI'm running into this same issue on ZC706 nist qc2 master variant, attempting to boot from SD with an external clock. The most recent build 151734 does not boot. The first failing build is…

Feature Request: EdgeCounters for NIST QC2 gatewareOne of my colleagues has been trying to test the gateware and ran into the following problem; calling `fetch_count` on the counter hangs as if there was no input to fetch, despite an earlier call…

ZC706/QC2 accessing devices from list causes hang/crash@mwojcik @sb10q we just saw another hang with a similar experiment (accessing devices from a list) - going back to a test setup to try to reproduce consistently. Using zc706 DRTIO master build 123830.

Moninj connection causes core panic on zc706Tested 1f95b5970c93c3e047c4cbd9b1933b9c64b7e22b on both a live system and another with no satellite, I'm still getting the same behaviour as before (live system: unpingable, no satellite: 8ms error…

Moninj connection causes core panic on zc706Built from e34381094b to test; at the moment I have a zc706 test setup with no satellite, and our live system with a single satellite. I'm working on having a satellite for the test setup to avoid…

Moninj connection causes core panic on zc706This happens only with satellite data in the device_db, good catch; I've attached a minimal device_db that still elicits a crash, regardless of whether the satellite is connected. I'll try the…

Moninj connection causes core panic on zc706I don't appear to have the same issue with https://nixbld.m-labs.hk/build/121703, so this seems to be DRTIO gateware related.

ZC706/QC2 accessing devices from list causes hang/crashefc432352e appears to have fixed the hangs so far - thanks, sounds like it was a bear to identify! I'll continue to keep an eye out for any recurrences.

ZC706/QC2 accessing devices from list causes hang/crash@sb10q the kernel hangs are pretty catastrophic: at the moment the DRTIO gateware is unusable because of the hangs. There doesn't appear to be a workaround at the moment, since even accessing the…

ZC706/QC2 accessing devices from list causes hang/crashSame problem with ACPKI (https://nixbld.m-labs.hk/build/121087). Also not specific to DDSs; an exactly analogous experiment using 12 TTLs and `ttl.output()` in place of `dds.init()` failed in the…
