mithrocr1901_modern: so, were are we at? I'd like to get the xmodem stuff merged03:04
cr1901_modernmithro: Your IRC log appears to be broken, but I was trying to find last time we talked. I said I couldn't implement SFL as you wanted (SFL doesn't really have provisions for "reading everything into a big buffer") and you said you'd take a look and we discussed.03:10
cr1901_modernAnd then we both got busy :P03:10
cr1901_modernmithro: In other news, been looking at qemu-litex to fix the timer bug, finish formatting flterm changes, and add quad-SPI support to litex for opsis03:12
cr1901_modern(none of which are done, but flterm changes take 5 minute)03:13
mithroWe can merge xmodem before sfl, right?03:13
cr1901_modernmithro: Sure. I need to finish adding quad bitbang SPI support to litex first03:14
cr1901_modernmithro: Also disregard the "IRC logs broken" msg, I'm an idiot03:14
cr1901_modernmithro: Here we go:
mithroJimmo has added xmodem to the pic firmware on the mimasv2 - I want to check that flterm and your gateware implementation are all compatible03:16
mithrocr1901_modern: I should have added "bug me if you don't hear back from me" :-)03:18
cr1901_modernwell flterm works (mimasv2) to upload firmware03:18
cr1901_modernmithro: That's fair/my oversight03:19
cr1901_modernI kinda wish I got to modify my lib for PIC tho :P (maybe I still might after this is done)03:19
mithroDoes Minicom / tetraterm (or what ever is used on windows) also work?03:20
cr1901_moderndidn't try... please wait two mins03:21
mithroOh, and the python xmodem library03:22
cr1901_modernmithro: The transfer itself works fine in Tera term but the terminal hangs afterward... checking now03:28
cr1901_modernActually come to think of it, lots of characters are garbled (but the xfer succeeded). I think this was the reason I used Linux in the first place to access the mimasv2 board. The Windows driver is just screwy03:30
cr1901_modernmithro: This is a known issue, btw
cr1901_modernmithro: I happen to have a PIC programmer to upgrade the PIC firmware if necessary03:34
mithroBy garbled - do you mean the transmitted data that was written broken?03:35
cr1901_modernmithro: The transfer succeeded, so the transmitted data wasn't written broken. But I can't tell whether the code after the transfer succeeded or not b/c the terminal hung on me afterwards. >>03:38
cr1901_modernmithro: Since then, I've reset the device twice, and I've gotten to the HDMI2USB prompt both times successfully03:39
cr1901_modernmithro: By garbled, I mean THIS is what I see upon pressing reset:

cr1901_modernJust now, I disconnected the mimasv2 from Windows, and reconnected it to the Beagle. This is what I see when I press reset on mimasv2:

* CarlFK[m] uploaded an image: file1504669289734.jpg (380KB) <>03:42
CarlFK[m]mithro: v2. It defaults to on03:43
mithroCarlFK[m]: that kind of scares me a little...03:43
mithrocr1901_modern: I think Jim's firmware for the pic should fix this03:44
cr1901_modernmithro: How do I flash it the first time? Does it require an actual PIC programmer?03:49
cr1901_modernmithro: Firmware update from tera term was successful w/ default PIC firmware03:49
tpbTitle: GitHub - jimmo/numato-mimasv2-pic-firmware (at
mithroOnly need a pic programmer if you screw it up...03:50
cr1901_modernwhere's the xmodem code for it?03:51
mithroDunno if Jim has pushed that yet...03:53
cr1901_modernmithro: Also, just to reiterate; firmware update succeeded from Windows Tera Term. This tells me that the garbled chars are on the receiver end03:54
mithroCurrently you need this hack with his firmware -
tpbTitle: HDMI2USB-litex-firmware/ at master · timvideos/HDMI2USB-litex-firmware · GitHub (at
mithroAnd nobody has tested under windows at all03:55
cr1901_modernick- Jim can only build his code w/ the demo compiler :/?03:56
cr1901_modernmithro: Does numato provide a download of the original f/w anywhere, just in case?04:10
cr1901_modernmithro: Answer to the above appears to be "no"... ah well

mithroIshan_Bansal: I'm doing a code review for your pull request now06:04
mithroIshan_Bansal: Understand you have exams at the moment so will be slow to respond to the comments06:04
cr1901_modernmithro: No, not yet, but I'm about to sleep06:27
cr1901_modernmithro: I meant the original firmware provided by Numato06:28
mithrocr1901_modern: I'm sure we had a copy somewhere06:30
mithrocr1901_modern: Let me get back to you06:30
mithroIshan_Bansal: Just some comment and formattting fixes and we can merge that pull request!06:33
