mithrotumbleweed: Do you know "Peter van der Walt"?04:31
tpbTitle: (at
tumbleweedmithro: nope04:37
mithroCarlFK: cool!04:40
tumbleweedhe is a joburg person, I'm from cape town04:42
tumbleweeddoesn't mean I don't know people there, but far fewer...04:42
mithrotumbleweed: I wonder if he has been to LCA, he's name sounds *very* familiar04:42
mithromaybe he's Jon Oxer's friend?04:43
CarlFKmithro: yeah, sounds familiar to me too04:43
mithroshenki: Do you know?04:45
mithroWell, the timvideos project must be doing something right - we are now getting spam sent to our mailing list04:46
mithroCarlFK: can you get pdp7 to contact me sometime?04:47

CarlFKmithro: i'll try but I have trouble getting him other than when I see him in person05:27
mithroCarlFK: I never see him in person, so it's a bit harder for me :P05:32

CarlFKmithro: what will it take to get the hdmi2usb to route? hdmi audio to a usb audio device?05:43
CarlFKmithro: I miss not being able to use the camera audio as my compressor,  a2d and cable etc.05:44
mithroCarlFK: It's non-trivial05:44
mithroCarlFK: It also has a lot of dependencies05:46
CarlFKHmm, I may keep using my SD cameras and.. ugh.. firewire.05:50
mithroCarlFK: Find me some more developers and we can make it happen :P05:53

xfxfmithro: not that this helps, but 2x to what CarlFK says06:49
mithroxfxf: same response :P06:49
xfxfbeing able to just take in the audio from my camera would probably mean i record more things06:49
xfxffrom what you said before there are two parts to this06:50
xfxfimplementing the interface in the FX206:50
xfxfand then implementing the FPGA stuff06:50
xfxfi have zero chance at the latter (unless misoc/migen makes this stupidly easy) but how hard would the FX2 stuff be?06:50
mithroxfxf: correct06:50
xfxfkinda interested in having a crack - that said, time06:50
mithroxfxf: before you do that, I recommend finishing my fx2 refactor06:50
*** _florent_ has joined #timvideos06:51
xfxfre the FPGA stuff, i assume the core is already interpreting the HDMI stream and just ignoring the audio bits06:51
xfxfassume the FPGA would need to read those bits + convert it to the format USB audio expects?06:52
mithroxfxf: we ignore the whole "data island" section of the HDMI stream06:52
xfxfi'll do some reading to better understand06:52
xfxfyour camera is only 15fps06:56
xfxfCarlFK: re your video above06:56

shenkimithro: ok, kernel patches sent out, im free again09:54
shenkimithro: did you sort out your linker issues?09:54
mithroshenki: nope, I just bumped everything down09:56
mithroI assigned the bug to you :-P09:57
mithroshenki: just trying to get the HDMI output up and working09:57
_florent_mithro: on the ms6?10:03
mithro_florent_: yeah10:03
mithro_florent_: I expect to see lots of fifo underflows/overflows10:04
_florent_with low resolution, it should be OK10:04
mithroahh true10:04
_florent_maybe worth trying 640x480 first10:05
mithro_florent_: yeah10:05
_florent_is it rounting fine? (I imagine you only have the CPU + HDMI in + HDMI out?)10:06
mithro_florent_: Not quite at that stage10:06
mithro_florent_: the BaseSoC routes pretty quickly10:06
mithro_florent_: like in under a minute10:06
shenkiyeah. it's great :)10:06
_florent_do you have a .srp you can share for the whole SoC?10:08
_florent_the synthesis report from ISE10:08
mithro_florent_: possibly, where might I find it?10:08
_florent_it should be in the build directory, where the .bin is generated10:09
mithroshenki: You should update to my shenki-minispartan6+ branch10:09
_florent_btw, are you using lm32 or mor1kx?10:11
mithroonce I finish the minispartan6 stuff, I'll rebase my mor1k stuff ontop of this10:11
mithro_florent_: so, the hdmi_out doesn't like a pack_factor of 110:20
_florent_what's the error?10:22
mithro_florent_: there are a bunch of Signal(max=pack_factor) which becomes Signal(max=1) which is effectively always zero10:23
_florent_ok, can you try hacking _FIFO for now:10:25
_florent_- remove unpack_counter10:25
mithrogah, this is going to be frustrating - ERROR:Pack:2310 - Too many comps of type "PLL_ADV" found to fit this device.10:56
mithroThe SLX25 has only 2 PLL_ADVs10:56
mithro_florent_: enabling the HDMI output causes the sdram memory test to start failing occasionally11:16
mithro_florent_: and I'm pretty sure its because of the TIG stuff11:17

CarlFKmithro: "Any possibility of doing live streaming this year?"  woo!!!18:18
CarlFKumm.. yes.  but I am not really sure what to use.   Event is in May, so plenty of time.18:19
