kcu105 still doesn't work after reprogramming the maxim pmbus stuff...
<sb0>
it seems 3.3V is short-circuited to ground, i can hear the coil of the regulator attempting to restart, and the maxim software reports an overcurrent on that rail

_florent_: do you have any idea of what can cause the FPGA-DAC latency to vary between reboots by about half a SYSREF period, when SYSREF meets setup/hold at both?
<sb0>
(period of the *current* SYSREF. decreasing the SYSREF frequency has no impact on the timing variation)
<sb0>
to clarify: I'm getting two possible latency values, and they differ by half a SYSREF period
<_florent_>
sb0: if in understand correctly, if you change the SYSREF frequency, the variation is always a half SYSREF period?
<sb0>
_florent_: correct
<sb0>
well I only tried 1/2 the original frequency
<_florent_>
i don't know for now, but i'll think about it

I modified the code to boot from bram and .. at least I now am getting something.. I really did not expect it to work at this point

keesj: modifying the uart terminal's settings to automatically add carriage-return with each new line should fix the weirdly indented output
<keesj>
after flashing I need to really take the power off (the reset button does not work) but once booted I can press the reset button. the boot now looks like https://pastebin.ubuntu.com/p/D4cRmdn7YP/
<keesj>
I imagine that If I want to save some memory blocks I need to move the "bios" to execute in place in spi flash?
<keesj>
if possible I would like to keep the ddr3 memory free for experiments

[smoltcp] pothos commented on issue #269: I think most times I looked at the smoltcp log message about the segment not being in the receive window, it was because it was a retransmitted packet which was not needed anymore and thus not in the window. Looking at my wireshark and the here posted wireshark labels I have doubts about the quality of the label names. E.g., the packet before the `ACKed unseen segment` label con

[artiq] hartytp commented on issue #1256: Note to self: the current delay in `get_profile_mu` isn't large enough and pretty deterministically gives underflows. Increasing to `6us` fixes. https://github.com/m-labs/artiq/issues/1256#issuecomment-458978837
