| sab_123 | mithro, to get started for the UART, I would write from USB into an end point after setting the correct vid and pid and use the hardware UART after setting up the timer . FOr the rx side, I would first set the isr interrupt after receiving the data arm the endpoint and wait correct? | 03:27 |
| sab_123 | mithro, I remember that the last time we had this conversation you had some doubts if I understtod correctly. Just want to make sure this is what you need | 03:28 |

| sab_123 | mithro, UART needs to be bitbanged too right? | 04:52 |
| sab_123 | mithro, because like you were saying , not all have serial ports | 04:52 |
| mithro | sab_123: yes, there are multiple different possibilities for the UART side - hardware uart, bit banged uart, fifo | 04:58 |
| sab_123 | ok mithro , got it | 04:59 |
| sab_123 | mithro, for the auto vectoring , on everyline I see BYTE dummy=INT2JT; which doesnt seem to be used at all. Do you want me to remove this?? | 05:11 |

| mithro | tumbleweed: I'm be around a bit later if you have people who want to hack on Opsis / HDMI2USB stuff | 08:02 |
| olasd | sure | 08:03 |
| olasd | (yes, I'm frustrated from yesterday :P) | 08:03 |
| mithro | olasd: I'm around now | 08:53 |
| mithro | olasd: what are you trying to do? | 08:53 |
| olasd | so, I have one of the Opsis boards DebConf bought in front of me; I'm trying to flash a more recent firmware to try and get some more video modes available | 08:54 |
| mithro | https://www.youtube.com/watch?v=GZNDQjCqIUM | 08:55 |
| mithro | olasd: okay - step 1 is to get the FX2 on the board into "JTAG programming mode", there are a number of different ways to do that | 08:55 |
| olasd | (we're using one of the three other boards in 720p mode; the last one was DOA / the USB doesn't enumerate) | 08:55 |
| olasd | right, thus far I'm following :) | 08:55 |
| mithro | olasd: The "firmware" for running the FX2 in JTAG programming mode comes from my ixo-usb-jtag repository | 08:56 |
| mithro | olasd: https://github.com/mithro/ixo-usb-jtag | 08:57 |
| tpb | Title: GitHub - mithro/ixo-usb-jtag: usb-jtag - Altera USB Blaster Emulation with a FX2 (at github.com) | 08:57 |
| mithro | olasd: or the ixo-usb-jtag deb | 08:57 |
| mithro | It can be loaded using the fxload command | 08:57 |
| mithro | olasd: I have a tool called "HDMI2USB-mode-switch" which is designed to make it easy to do this | 08:58 |
| mithro | olasd: but it needs a bunch of love to get into a good state | 08:59 |
| *** sab_123 has quit IRC | 08:59 | |
| mithro | olasd: https://github.com/mithro/HDMI2USB-mode-switch/tree/opsis-prod and https://github.com/timvideos/HDMI2USB-mode-switch/ | 08:59 |
| tpb | Title: GitHub - mithro/HDMI2USB-mode-switch at opsis-prod (at github.com) | 08:59 |
| mithro | olasd: if you know people who know Python, they could definitely help with finishing that stuff | 09:03 |
| olasd | ok | 09:03 |
| mithro | olasd: it would be good to get it packaged up for debian too | 09:04 |
| mithro | then you could just go | 09:04 |
| mithro | hdmi2usb-mode-switch --mode=jtag | 09:04 |
| olasd | that worked | 09:06 |
| olasd | \o/ | 09:06 |
| mithro | olasd: which works? :P | 09:11 |
| olasd | the jtag mode switch | 09:12 |
| mithro | olasd: what output did you get? | 09:15 |
| olasd | mithro: I'm now in a state where the board registers as idVendor=16c0, idProduct=06ad (Product: Opsis (JTAG Mode)). | 09:15 |
| olasd | the output was just "found 1 board" | 09:15 |
| mithro | olasd run it with --verbose :) | 09:15 |
| mithro | olasd: you'll see the fxload and other commands it runs | 09:16 |

| mithro | Probably want to remove the eeprom programming steps | 09:17 |
| olasd | should I replace the .bin with something newer? | 09:18 |

| tpb | Title: GitHub - timvideos/HDMI2USB-misoc-firmware: A version of the HDMI2USB firmware based around the misoc+migen tools produced by m-labs. (at github.com) | 09:21 |

| mithro | olasd: but you could use prebuilt ones from https://github.com/timvideos/HDMI2USB-misoc-firmware | 09:21 |
| tpb | Title: GitHub - timvideos/HDMI2USB-misoc-firmware: A version of the HDMI2USB firmware based around the misoc+migen tools produced by m-labs. (at github.com) | 09:21 |

| tpb | Title: Allow user to add custom EDID mode · Issue #63 · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 09:24 |
| olasd | okay; the flashing seems to be unhappy | 09:28 |
| olasd | let me paste the full output | 09:29 |
| olasd | mithro: https://paste.debian.net/446079/ | 09:29 |
| tpb | Title: debian Pastezone (at paste.debian.net) | 09:29 |
| mithro | olasd: if you get a device DNA that looks like this | 09:32 |
| mithro | DNA = 110000001100000011000000110000001100000010011110101000111 (0x181818181813d47) | 09:32 |
| mithro | it means the ixo-usb-jtag is confused | 09:32 |
| olasd | I do | 09:32 |
| olasd | which means it is | 09:32 |
| mithro | https://www.irccloud.com/pastebin/M7GzLIST/ | 09:32 |
| tpb | Title: Pastebin | IRCCloud (at www.irccloud.com) | 09:32 |
| mithro | Switch to the serial mode and then back to the jtag mode | 09:32 |
| olasd | done, and DNA is still the same | 09:33 |
| mithro | olasd: power cycle and try again | 09:34 |
| mithro | we need to improve the FX2 firmware | 09:34 |
| olasd | DNA = 110000001100000011000000110000001100000011000000110000001 (0x181818181818181) | 09:35 |
| olasd | aha! | 09:35 |
| olasd | so; output was different and still failed; another serial -> jtag cycle and apparently the board is flashing | 09:37 |
| olasd | wrote 1507328 bytes from file spiflash/opsis_hdmi2usb-hdmi2usbsoc-opsis.bin in 56.280357s (26.155 KiB/s) | 09:38 |
| olasd | whee | 09:38 |
| mithro | yeah, 110000001100000011000000110000001100000011000000110000001 means that its just looping back the JTAG rather than getting to the FPGA properly | 09:41 |
| olasd | righto | 09:41 |
| olasd | hrm. | 09:48 |
| mithro | olasd: Possibly because it isn't resetting the FPGA properly | 09:52 |
| olasd | okay | 09:53 |
| olasd | so | 09:53 |
| olasd | I succeeded in flashing the HEAD revision of the HDMI2USB-misoc-firmware, that I built | 09:53 |
| olasd | but | 09:54 |
| olasd | mithro: https://paste.debian.net/446117/ is the output from make flash in the misoc-firmware repo | 09:56 |
| tpb | Title: debian Pastezone (at paste.debian.net) | 09:56 |
| mithro | It's kind of hard for me to read french - but it looks like the flashing part worked | 09:56 |
| olasd | ah, sorry | 09:57 |
| mithro | I think it says | 09:57 |
| mithro | make: *** No rule to make target "flash-fx2" necessary to "flash". Stop. | 09:57 |
| olasd | apparently there is no flash-fx2 target | 09:57 |
| olasd | yeah | 09:57 |
| olasd | the rest of the flashing worked | 09:57 |
| mithro | Yeah, you don't need to flash-fx2 on the Opsis and I haven't written the code to flash the fx on an atlys :P | 09:58 |
| mithro | olasd: if you power cycle after flashing | 09:58 |
| mithro | olasd: hopefully it will come up with new firmware | 09:58 |
| olasd | I did power cycle | 09:58 |
| mithro | olasd: did it come back? :P | 09:58 |
| olasd | and it just doesn't come back ;_; | 09:58 |
| mithro | olasd: it can take about 30 seconds? | 09:59 |
| mithro | olasd: what happens on the USB? | 09:59 |
| olasd | yeah; I see [72815.373462] usb 1-2: New USB device found, idVendor=2a19, idProduct=5440 appear | 09:59 |
| olasd | then disappear | 09:59 |
| olasd | and then nothing | 09:59 |
| mithro | olasd: sounds like the FPGA is resetting the FX2 but it isn't successfully loading the new firmware | 10:01 |
| olasd | *nod* | 10:02 |
| mithro | 2a19 5440 is the "FX2 has power but hasn't loaded new firmware" | 10:02 |
| olasd | yeah, I gathered that from the usb ids page | 10:02 |
| mithro | olasd: try disconnecting the FX2 RST jumper | 10:02 |
| mithro | olasd: and loading the serial mode | 10:02 |
| mithro | olasd: and see what the firmware is saying | 10:02 |
| mithro | olasd: tumbleweed wasn't smart enough to get a LowSpeedIO board right? | 10:02 |
| tumbleweed | it didn't seem like something that would be useful to us | 10:03 |
| mithro | you guys are in Vienna right? | 10:03 |
| tumbleweed | yep | 10:03 |
| * olasd nods | 10:03 | |
| mithro | tumbleweed: the LowSpeedIO has a UART on it, you can use that to connect to the serial console even when the FPGA is resetting the FX2 :P | 10:04 |
| mithro | makes it easy to debug what is going on with the FX2 | 10:04 |
| olasd | I'm sure we can find a ftdi somewhere | 10:04 |
| olasd | lots of people from the metalab around | 10:04 |
| tumbleweed | we found one :) | 10:05 |
| mithro | tumbleweed: but were you going to connect it :P | 10:05 |
| mithro | I guess you could try shoving some wires into the TOFE connector | 10:05 |
| tumbleweed | urgh | 10:06 |
| olasd | ah, yeah :-) | 10:06 |
| olasd | so anyway | 10:06 |
| mithro | olasd: btw - you have the SDA jumper connected right? | 10:06 |
| olasd | yes | 10:07 |
| olasd | I'm in serial mode; nothing happening on the serial port | 10:07 |
| mithro | olasd: hit enter? | 10:07 |
| olasd | I've done that :) | 10:07 |
| mithro | you might need to be quick to catch what ever its outputting? | 10:08 |
| mithro | I was sure that I asked for the FX2 serial lines to be put on a header, but it never seem to end up in the final design | 10:08 |
| olasd | yeah, don't look like it | 10:09 |
| olasd | :) | 10:09 |
| mithro | olasd: otherwise you could have connected a FTDI device there | 10:10 |
| mithro | olasd: _florent_ uses an adapter connected to the microSD pins | 10:11 |
| mithro | olasd: https://github.com/timvideos/HDMI2USB-misoc-firmware/blob/master/platforms/opsis.py#L256 | 10:11 |
| tpb | Title: HDMI2USB-misoc-firmware/opsis.py at master · timvideos/HDMI2USB-misoc-firmware · GitHub (at github.com) | 10:11 |
| olasd | okay; I've flashed the firmware from the mode-switch repo and the board is back | 10:13 |
| mithro | olasd: great | 10:13 |
| mithro | olasd: I haven't been testing with a production opsis board recently | 10:13 |
| mithro | olasd: so maybe something else is broken | 10:13 |
| olasd | :) | 10:13 |
| mithro | Now since it is 8:30pm on a Friday evening and SLUG is over, I'm going to head home | 10:25 |
| olasd | :) | 10:30 |
| olasd | well, I'm in a situation where i'm able to recover a working firmware, so I should be fine for a while | 10:31 |
| olasd | at some point we might try to do something about the board that doesn't enumerate usb, if someone brings an external jtag board | 10:34 |
| mithro | olasd: can you generate gateware? | 10:51 |
| olasd | mmm | 10:52 |
| olasd | yes, I'm pretty sure make gateware succeeded earlier | 10:52 |
| mithro | IE "make gateware" | 10:52 |
| olasd | I have been multitasking as it takes a while, however | 10:53 |
| mithro | Btw you did an "export BOARD=opsis" right? | 10:53 |
| olasd | yeah :) | 10:53 |
| mithro | Ha great, I was thinking maybe you had flashed Atlys gateware on an Opsis which doesn't work | 10:54 |
| mithro | olasd: if your any good at packaging, it work be good to get lm32 and or1k cross compilers into Debian | 10:55 |
| olasd | I won't touch cross compiler packaging with a ten feet pole, sorry :) | 10:55 |
| olasd | I tried that a few years back, it was a horrible horrible experience | 10:56 |
| mithro | That's why we currently get you a working cross compiler with conda | 10:56 |
| olasd | oh, yeah, I understand that; can't say I love it, but I've seen the other side | 10:57 |
| mithro | Lm32 stuff is all upstream | 10:57 |
| mithro | Dunno if they helps | 10:57 |
| olasd | (getting a bare metal arm cortex m3 toolchain properly packaged; I think I started in 2008, got some packages working, but spent years explaining that no, the linux toolchains couldn't build properly for a bare metal target) | 10:57 |
| olasd | (then I threw up my hands in the air and got back to doing more productive stuff) | 10:58 |
| mithro | olasd: you a C programmer? | 10:59 |
| olasd | it's been a long while since I've done embedded stuff; I maybe last did some real C programming in 2009 or so, and my last fray with vhdl was in 2010. and I don't have nearly enough free time to get back into it unfortunately | 11:00 |
