Cfr. JTAG +09:15 < geertu> Make one yourself, if you cannot find one? 2 IDC connectors + 1.27mm ribbon cable +09:15 < wsa> hmm, i found hw adapters but no cable +09:16 < wsa> maybe jtag will give me better search results +09:16 < wsa> it is not so much for me but for Magnus board farm :) +09:17 < geertu> damm: BTW, does your Falcon have the ether subboard? +09:17 < damm> yep +09:17 < wsa> I'll check +09:17 < wsa> (adapter cables) +09:19 < wsa> geertu: AFAIU the next version of renesas-drivers should have the V3U PFC and GPIO patches, or? +09:19 < geertu> wsa: The previous one +09:19 < geertu> had v2 +09:20 < geertu> actually the one before, too +09:21 < wsa> yes +09:22 < wsa> sorry, my question was not precise +09:23 < wsa> the patches are all good to go, so they will come into the nex ren-drivers release via -next and not seperate topic branches, or? +09:23 < geertu> correct +09:24 < wsa> great news! +09:24 < wsa> so, discussion topics from your side? +09:26 < wsa> okay, then it seems we can move to the core meeting +09:26 < wsa> thank you everyone! -- cgit v1.2.3
