CarlFKmithro: Opsis board.  I hooked up a pi normal cable, solid 1280x0, added extender, solid 1280x72004:55
mithroThat is useless information04:57
mithroYou need the debug info04:57

CarlFKmithro: retweeted06:42
CarlFKmithro: I have the extender hooked up.  now I am getting 1280x0 and 0x0.  What is the command to get the debug info?06:44
CarlFKand does the stock firmware have it  ? firmware revision: 0607e926, built Jan  8 2016 23:55:4706:45

CarlFKmithro: how do I update the Opsis?20:47
CarlFK[email protected]:~/lca/HDMI2USB-firmware-prebuilt/archive/lca2016/v0.0.0-606-gebbfdc5/opsis/hdmi2usb$ openocd -f board/numato_opsis.cfg -c "init; pld load 0 opsis_hdmi2usb-hdmi2usbsoc-opsis.bit; exit"20:47

CarlFKmicolous: do you know how to update an Opsis with new firmware?22:34
CarlFKmithro: are there docs for updating the Opsis, or should I start creating them?23:00
mithroThe closest I got to instructions is https://hdmi2usb.tv/drivers/ I think23:05
mithroThere might be more somewhere at opsis.hdmi2usb.tv23:05
mithrohttps://opsis.hdmi2usb.tv/getting-started/jtag.html maybe?23:06
mithroIf you promise to update the docs, I'll give you some more instructions.23:07
mithroCleaning and merging the Opsis production stuff in my fork of the modeswitch is on my endless todo list.23:08
mithroThe stuff I linked about USB IDs might have links/info too.23:10
CarlFKmithro: is jtag always a physical connection,  or is there a virtual one over usb too?23:32
mithroJTAG is mostly a protocol23:37
mithroThe FX2 on the Opsis and Atlys work as a JTAG programmer.23:38
mithroThat is what the ixo-usb-jtag code does - make the FX2 appear as an Altera USB Blaster JTAG cable23:39
CarlFKmithro: I'v always wondered about that.23:43
CarlFKmithro: I looked over all the links, nothing like this so I'll create.  is this a good place: https://github.com/timvideos/HDMI2USB-misoc-firmware/wiki23:44

mithroOpenOCD actually does most of the work though. A USB JTAG cable normally just allows you to toggle a bunch of IO lines together.23:45
mithroUSB JTAG cables don't really do much - normally just let you toggle IO pins. OpenOCD contains all the logic on how and when to toggle them.23:48
mithroBah23:49
mithroPutting it somewhere is better then nowhere. If it's Opsis stuff, then it should go in the Opsis docs....23:51
CarlFKI'm running off for dinner, but will hurry to get back to this23:53
CarlFKI am working on Opsis now, but only because it is plugged in. I'll get to Atlys too.23:54
CarlFKbye!23:54
