| cr1901_modern | mithro: Do you have a pinout for the JTAG header? | 02:31 |
| mithro | cr1901_modern: On? | 02:35 |
| cr1901_modern | mithro: On Opsis... I wanted to see whether I could program the FPGA from Windows via direct connection to FPGA's JTAG pins | 02:35 |
| cr1901_modern | (this appears to be "no") | 02:35 |
| mithro | cr1901_modern: You should most definitely be able to do that | 02:36 |
| mithro | cr1901_modern: That is how _florent_ does it | 02:36 |
| mithro | cr1901_modern: The pins are standard positioned and labeled on the silkscreen | 02:37 |
| cr1901_modern | Oh... oops | 02:37 |
| cr1901_modern | mithro: I assumed I couldn't do it b/c I read the FPGA's JTAG pins go the the FX2 chip | 02:39 |
| mithro | cr1901_modern: They do | 02:39 |
| cr1901_modern | Is it a chain of multiple devices? | 02:39 |
| cr1901_modern | FX2, then LX45? | 02:40 |
| cr1901_modern | Nope, accoding to OpenOCD, only thing there is the FPGA... | 02:54 |
| mithro | cr1901_modern: Correct | 02:58 |
| cr1901_modern | hrm, Tera Term also can't display characters properly in windows using this driver ._. | 03:03 |
| cr1901_modern | And neither can PuTTY (which numato themselves use | 03:05 |
| cr1901_modern | mithro: ^^ What's the easiest way to get in contact w/ Numato? | 03:06 |
| mithro | cr1901_modern: With the Mimas? | 03:06 |
| cr1901_modern | mithro: Sadly, it extends to the Opsis too | 03:07 |
| mithro | cr1901_modern: We don't have windows drivers for the Opsis? | 03:07 |
| cr1901_modern | mithro: No, we do... just the serial port has the same problem w/ garbled characters on the Opsis as it does w/ the Mimasv2 | 03:08 |
| mithro | cr1901_modern: Where are the Opsis windows drivers? | 03:09 |

| mithro | I started creating Windows drivers here -> https://github.com/mithro/HDMI2USB-and-Numato-Opsis-Windows-Drivers but never finished it... | 03:10 |
| tpb | Title: GitHub - mithro/HDMI2USB-and-Numato-Opsis-Windows-Drivers: Drivers and related code/data for improving the hardware experience for the HDK on Windows (at github.com) | 03:10 |
| mithro | Wow, numato's website just changed... | 03:10 |
| mithro | I've never seen them before -- so no guarantees they work at all :-P | 03:11 |
| xfxf | lol what | 03:12 |
| xfxf | official windows drivers!? | 03:12 |
| cr1901_modern | "you'll need a code-signing certificate" there's a way around this so you can deploy self-signed drivers without requiring test mode | 03:12 |
| xfxf | wow | 03:12 |
| cr1901_modern | but I don't remember the details | 03:12 |
| xfxf | they've actually made proper inf/cat files for the usb device id's | 03:12 |
| xfxf | just a cursory look over the zip contents just makes the device recognised properly under windows (capture, terminal, tofe lowspeed io), doesn't provide any software | 03:13 |
| xfxf | mithro: i'm amused this happened without your knowledge lol | 03:13 |
| xfxf | also this means they're selling them again? | 03:13 |
| mithro | xfxf: Well, I sent them files to sign and stuff and they sent me stuff back - I didn't realize they had published stuff | 03:14 |
| xfxf | mithro: ah, the contents of their zip look the same as your repo | 03:14 |
| cr1901_modern | ... bahaha, really :P. Nice! | 03:14 |
| mithro | It *definitely* wasn't finished | 03:14 |
| xfxf | i rly should finish the bloody UI | 03:14 |
| cr1901_modern | in any case, something's very wrong w/ both Numato serial ports | 03:14 |
| mithro | xfxf: Yes you should | 03:15 |
| cr1901_modern | I don't have a way to debug this... | 03:15 |
| xfxf | i was quite enjoying writing it, different paradigm to web programming | 03:15 |
| xfxf | actually had a legitimate reason to use explicit threading | 03:15 |
| mithro | cr1901_modern: I wouldn't waste time on it | 03:15 |
| cr1901_modern | mithro: I don't intend to, but it's still a bug/problem for windows development. | 03:16 |
| mithro | cr1901_modern: Log a bug on the HDMI2USB-fx2-firmware repo about it | 03:16 |

| cr1901_modern | mithro: I just realized something (I think)... the opsis bitstream (i.e. the .bit/.bin file generated by ISE) embeds an extra copy of the LiteX BIOS in addition to the copy that's stored in flash. Is this correct? | 22:28 |
| cr1901_modern | cc: _florent_ ^^ | 22:36 |
| mithro | cr1901_modern: yes | 22:58 |
| mithro | cr1901_modern: we want the same flash layout for consistence | 22:58 |
| mithro | But having an embedded gateware means we don't have to flash the bios seperately | 22:59 |
| cr1901_modern | mithro: So why doesn't mimasv2 have the same issue? | 23:04 |
| mithro | The mimasv2 doesn't have the space being an lx9 | 23:07 |
| mithro | cr1901_modern: at some point the lx45 in the Atlys / Opsis might get to full and we have to kick the bios out | 23:08 |
| mithro | We should probably do that for the hdmi2usb target at some point | 23:09 |
| cr1901_modern | I see... I tried reprogramming the opsis earlier... just as a test I loaded a bitstream by itself (no flash), and was surprised to see the LiteX BIOS w/ a "Sept 6, 2017" date | 23:09 |
| cr1901_modern | (instead of a MiSoC BIOS w/ Jan 2016 date :P) | 23:09 |
| cr1901_modern | So it threw me off a bit | 23:09 |
| mithro | Sorry | 23:10 |
| cr1901_modern | No worries | 23:11 |
| cr1901_modern | right now I have a bigger issue. I flashed new firmware successfully, but I lost ttyACM0 :/ | 23:11 |
| cr1901_modern | dmesg says: Product: Opsis (JTAG Mode) | 23:12 |
| mithro | It does make it quick to load the gateware and then tftp the firmware during development | 23:12 |
| cr1901_modern | mithro: True :P | 23:12 |
| mithro | cr1901_modern: the FPGA will reset the FX2 after booting | 23:12 |
| cr1901_modern | So this indicates the FPGA failed to boot properly (because it didn't exist JTAG mode)? | 23:13 |
| mithro | Not necessarily | 23:13 |
| mithro | cr1901_modern: I sent you a lsio board right? | 23:14 |
| cr1901_modern | mithro: Yes, you did. It's attached to my Opsis right now | 23:15 |
| mithro | cr1901_modern: you can use the USB UART on that too see everything even when the FX2 is being reset | 23:15 |
| mithro | You have to set an environment variable to get that to happen | 23:16 |
| mithro | To build a gateware with lsio board support | 23:16 |
| mithro | Otherwise, just remove the jumper that will prevent the FPGA from resetting the FX2 | 23:17 |
| cr1901_modern | mithro: Worth a shot. B/c right now my current status is... I can program the Opsis flash via my JTAG adapter (TLDR; it is most convenient for me right now compared to the "mode switch" way). But ttyACM1 decided to disappear when I power cycled the board | 23:17 |
| cr1901_modern | (power cycle == "unplug it/plug it back in") | 23:18 |
| mithro | https://opsis.hdmi2usb.tv/features/usb-peripheral.html#cypress-fx2-reset-circuit | 23:18 |
| * cr1901_modern takes a look | 23:19 | |
| mithro | What target are you flashing with at the moment? | 23:19 |
| cr1901_modern | The flash.bin generated from opsis_lm32_base + bios + hdmi2usb firmware | 23:19 |
| cr1901_modern | I flashed it at address 0 | 23:20 |
| mithro | The fx2 should come up in JTAG mode in that config in theory | 23:20 |
| mithro | Btw at some point I want to get mode switch working on windows | 23:21 |
| cr1901_modern | mithro: Unplugging opsis USB cable now and plugging back in. | 23:22 |
| mithro | Now we have fx2 loader in python that should be more doable | 23:22 |
| cr1901_modern | mithro: "Btw at some point I want to get mode switch working on windows" Understood. Just doing what I thought would be the quickest way :P. | 23:23 |
| mithro | Yeah, perfectly reasonable | 23:23 |
| mithro | I was just hinting that might be on your to-do list next :-) | 23:24 |
| cr1901_modern | mithro: That too :P | 23:25 |
| cr1901_modern | mithro: Okay, I have some good news and bad news | 23:25 |
| cr1901_modern | good news is Linux detects the device | 23:25 |
| cr1901_modern | bad news is everything else: https://hastebin.com/rufipefago.vbs | 23:25 |
| mithro | If we can port the xmodem code to the FX2 (and JTAG rather than SPI flash mode) | 23:26 |
| mithro | cr1901_modern: that means the FX2 is in failsafe mode | 23:26 |
| cr1901_modern | mithro: It is my intent to make libmodem able to target the 8051's w/ the limited buffer space | 23:26 |
| cr1901_modern | mithro: I swear I didn't do anything bad... I think | 23:26 |
| mithro | IE the FX2 was reset and it was unable to load the FX2 firmware off the FPGA | 23:27 |
| cr1901_modern | VID/PID don't match Cypress in the dmesg output I linked | 23:28 |
| mithro | https://opsis.hdmi2usb.tv/getting-started/usb-ids.html#summary | 23:28 |
| mithro | Btw would appreciate help with updating the docs too :-) | 23:29 |
| cr1901_modern | mithro: Okay that's fair... let me just un-hose my Opsis first | 23:30 |
| mithro | https://github.com/timvideos/HDMI2USB-numato-opsis-docs?files=1 | 23:30 |
| tpb | Title: HDMI2USB-numato-opsis-docs/ at master · timvideos/HDMI2USB-numato-opsis-docs · GitHub (at github.com) | 23:30 |
| cr1901_modern | mithro: According to your table, I'm in "Unconfigured mode" | 23:33 |
| mithro | Yeah | 23:35 |
| * cr1901_modern consults FX2 datasheet | 23:35 | |
| mithro | Means the FX2 booted from the EEPROM but was unable to read a full firmware from the FPGA | 23:35 |
| mithro | You won't find it there | 23:36 |
| cr1901_modern | mithro: Oh, I was wondering how the FX2 knows which I2C secondary it knows to talk to | 23:36 |
| cr1901_modern | Since the FPGA and phyiscal EEPROM can both serve that role | 23:36 |
| mithro | cr1901_modern: You can now send the FX2 firmware via USB using fxload | 23:37 |
| mithro | cr1901_modern: the FX2 loads this program from the EEPROM -> https://github.com/timvideos/HDMI2USB-fx2-firmware/tree/master/microload | 23:38 |
| tpb | Title: HDMI2USB-fx2-firmware/microload at master · timvideos/HDMI2USB-fx2-firmware · GitHub (at github.com) | 23:38 |
| cr1901_modern | mithro: okay let me do that... | 23:39 |
| mithro | cr1901_modern: the EEPROM is only 128 bytes, it isn't really big enough to store a real FX2 program | 23:39 |
| cr1901_modern | Wait the docs say 2048 kilobits | 23:39 |
| mithro | 2048 kilobits == 256 kilobytes -- but the top 128 bytes are not writable IIRC | 23:41 |
| mithro | https://github.com/mithro/HDMI2USB-mode-switch/blob/opsis-prod/opsis_eeprom.py | 23:44 |
| tpb | Title: HDMI2USB-mode-switch/opsis_eeprom.py at opsis-prod · mithro/HDMI2USB-mode-switch · GitHub (at github.com) | 23:44 |
| cr1901_modern | Okay, got a i2c-prod.hex | 23:45 |
| mithro | That doc needs some updates - the eeprom that was populated ignores the i2c address lines... | 23:45 |
| mithro | cr1901_modern: you don't need that | 23:45 |
| mithro | cr1901_modern: all you need to do is an "fxload <fx2 firmware>" - "hdmi2usb-modeswitch --mode=jtag" will do it for you | 23:47 |
| mithro | cr1901_modern: or build a gateware with lsio support and then use the UART on that to see what is going wrong... | 23:47 |
| mithro | cr1901_modern: don't touch the eeprom otherwise it will be a pain to get working again :-P | 23:49 |
| mithro | paddatrapper: you going to be around this weekend? | 23:49 |
| cr1901_modern | mithro: I won't lol... but at some point I'd like to be competent enough that I could touch the eeprom safely :P | 23:52 |
| cr1901_modern | (Also recall I do have an external JTAG/SPI/I2C breakout programmer) | 23:53 |
| cr1901_modern | So as incompetent as I might be tonight, it's not likely I'll actually truly hose my device (famous last words) | 23:53 |
| mithro | cr1901_modern: it's actually pretty hard to get into a state were you can't recover by just removing some jumpers | 23:53 |
| cr1901_modern | mithro: Okay, so now I'm back into JTAG Mode for the USB device returned | 23:55 |
| mithro | cr1901_modern: what did you do? | 23:56 |
| cr1901_modern | "hdmi2usb-modeswitch --mode=jtag" | 23:56 |
| cr1901_modern | as soon as it finished dmesg showed the device reporting itself in JTAG mode | 23:56 |
| cr1901_modern | Unplugging the USB cable and back in- device still shows up in JTAG mode | 23:58 |
