_florent_: Did you ever finish integrating picorv32 into litex? I got it to the state where it boots again, not sure if I should sit down and implement IRQ support or you have a branch with that somewhere already :)
<_florent_>
q3k: no it's still missing irq support, adding it would be really appreciated :)
<q3k>
alright, I'll hopefully send a PR your way tomorrow

rjo, where are the kasli schematics in pdf?

q3k: thanks (missing pieces of software should be indicated with /* FIXME */)
<key2>
why would a SyncFIFO input correctly in it's sink, but output only 0 instead of the values it read (with correctly setting the stream signal, just 0 as data) ?
<cr1901_modern>
timing violation?
<rjo>
sb0: according to the schematic, NC
<key2>
cr1901_modern: such as sink/source not being on the same timing ?
<cr1901_modern>
key2: I was thinking more that the data wasn't being held on the input to the FIFO long enough (setup time violation).

rjo, isn't tx_disable active low?
<rjo>
sb0: inverted. see schematic
<sb0>
hmm no. it's inverted on kc705 but not on other boards.
<sb0>
sayma should be fixed
<sb0>
the 74x245 is not inverting
<sb0>
the kc705 mosfet is
<rjo>
sb0: yes. i was thinking of mod_present.

_florent_, ERROR: [DRC REQP-1739] GTx R/TXOUTCLK drives inappropriate load: GTPE2_CHANNEL cell GTPE2_CHANNEL pin GTPE2_CHANNEL/TXOUTCLK (net: transceiver_txoutclk) should only drive BUFG, BUFH, BUFMR, MMCM or PLL loads, but drives one or more invalid loads such as BUFR cell BUFR. Please insert a BUFHCE (or a BUFMR, if the load is a BUFR) between the GT and its load(s).

rjo: Need to generate a spartan 7 single-tap proxy. Is this repo still the way to do it, despite the readme? https://github.com/jordens/bscan_spi
