paddatrappermithro: Trying to load firmware onto one of the fx2 boards using fx2load. Getting an error - Device not opened. Any ideas?17:02
CarlFK4am for mithro, so you will need to wait 4 or 5 hours.17:03
CarlFKpaddatrapper: can you pastebin the whole thing? I may recognize what's going on17:03
CarlFK[email protected]:~$ fxload -V17:04
CarlFKJan 28 2016 (development)17:04
CarlFK[email protected]:~$ apt-cache policy fxload ... wily/main amd64 Packages17:05
tpbTitle: Index of /timvideos/fpga-support/ubuntu (at
paddatrapperCarlFK: I'd forgotten about timezones...17:06
tpbTitle: debian Pastezone (at
paddatrapperI'm using the fx2load installed from examples/fx2load in the fx2lib repo. I'll try fxload17:07
CarlFKpaddatrapper: here is from my notes.txt collection of stuff that I have used: fxload -B libusb -D vid=0x16c0,pid=0x06ad -t fx2lp -I hdmi2usb.hex17:09
paddatrapperCarlFK: Thanks, I'll give it a try17:10
CarlFKthat may be for the Atlys borad17:11
CarlFKsomething else to try...17:11
CarlFKfrom my  fp = "{}/hdmi2usb.hex".format(pth);       run_cmd(["hdmi2usb-mode-switch", "--load-fx2-firmware", fp])17:11
paddatrapperCarlFK: Do you know where17:12
paddatrapperI can find a Debian version?17:13
paddatrapperNever mind... Found it in Debian repos already...17:14
CarlFKthere are a few versions of fx2load - I use the one in the PPA17:20
tpbTitle: debian Pastezone (at
CarlFKI may also use the one that some script git clone/build17:21
paddatrapperWhen using fxload17:21
CarlFKum, I'll need to get my board out and see what the output looks like, but need to run to the dentist now.  I should be back in about an hour17:22
paddatrapperNo problem17:23
paddatrapperCarlFK: setting the type to fx2lp fixed the issue17:32
*** hyades has quit IRC18:00
CarlFKpaddatrapper: what board are you flashing?18:29
paddatrapperCarlFK: EZ-USB FX2 dev board18:42
CarlFKpaddatrapper: ah, not one of the hdmi2usb things.  right?18:51
paddatrapperCarlFK: nope. Just working on the FX2 library18:51
CarlFKpaddatrapper:   is that the thing that is causing chars to drop if we send data too fast?18:54
paddatrapperCarlFK: Honestly I don't know, but I expect so18:57
CarlFKoh I so hope so18:57
paddatrapperAt the moment I'm working on USB audio capture18:58
CarlFKThat has been a little pain point.  there have been a few solutions - basically little bits of code to throttle .. but they all are kinda clunky, and one more thing to worry about18:58
paddatrapperYeah, at debconf we tried finding a neater solution, but think our best was sleeping for a few miliseconds between each character19:01
CarlFKhope that motivates you to try and fix the root problem  ;)19:03

paddatrapperCarlFK: It's on the list :)19:10

xfxfAFAIK the issue is no flow control, isn't it?23:51
xfxfthe solution I'd imagine would be to implement it23:52
xfxfas in, hardware flow control in the firmware23:52
