[artiq] sbourdeauducq commented on issue #911: Use the latest misoc from git (conda package probably available still, or you can trigger a build on Irc) we're not doing ci and full conda support for Sayma yet. https://github.com/m-labs/artiq/issues/911#issuecomment-362487333
<sb0>
boot is rather slow, did you wait long enough?
<_florent_>
i think... 20 minutes would be really slow... :)
<sb0>
are you using the board right now or can I try?
<sb0>
geez those sayma are such a pain in the ass
<_florent_>
i was going to ask you to try if possible

_florent_, okay, for some reason this shitty FPGA isn't reading its flash to get the bitstream; loading the .bit manually from JTAG works around the problem
<sb0>
(or the bitstream wasn't correctly loaded in the flash)
<_florent_>
sb0: hmm ok, can you eventually try to flash a bistream? (it could also be my bistream that is not working, but i don't know why it would be the case...)
<sb0>
okay, flashing now ...
<sb0>
I assumed you did those tests
<sb0>
_florent_, what allowable error window did you program into the DAC?
mumptai has joined #m-labs
<sb0>
if we want to check sysref s/h, that error window should be zero
<sb0>
did you scan the sysref phase and found phases for which REF_WLIM was set, indicating phase error outside the window?
<sb0>
_florent_, sayma-3 boots just fine when I flash it
<_florent_>
sb0: hmm
<sb0>
it even talks with sayma-1 with drtio
<_florent_>
sb0: can i try?
<_florent_>
sb0: for flashing, you are using the same command i use?
<sb0>
_florent_, ok I unlocked the board
<sb0>
open a terminal and do artiq_flash start. you should see the boot
<_florent_>
yes i'm doing that
<sb0>
my command was "artiq_flash.py -t sayma --srcbuild bin_satellite --preinit-command "ftdi_location 5:1" -V satellite", which is equivalent to yours
<_florent_>
ok i see the boot
<_florent_>
let's try to reflash my bistream
<sb0>
you can just load it
<sb0>
no need to flash
<sb0>
it's faster
<sb0>
unless you want to run your modified runtime too
<_florent_>
sb0: yes i'm setting the window to the minimum (1/2 DAC clk) and want to scan sysref with REF_WLIM
dlrobertson has quit [Ping timeout: 240 seconds]
<_florent_>
sb0: stilll not able to get my bistream working (by flashing or loading), i'll regenerate it...
