| ewen | mithro: Looks like TinyFPGA BX / MicroPython serial/boot doesn't work after 3a9127d08d8d0be9a68331bd71bf43fc216dbb26 | 02:39 |
|---|---|---|
| ewen | mithro: That commit and the next one don't build due to API conflicts (that's a Litex submodule update set). | 02:40 |
| ewen | mithro: Commits that do build after that don't show Litex BIOS or anything on serial | 02:42 |
| ewen | (Looks like there are 71 commits after that.) | 02:43 |
| ewen | mithro: e4c6ffa96f6ac4048181363f9a9be2dbea4b19c3 which is the next one that builds for me, doesn't work (no BIOS/serial console messages). | 02:55 |
| ewen | FTR da7488c2ab5e3d496ba4ecb5e482458302fb1c15 is the last working commit that builds, and gives BIOS/serial. | 02:59 |
| ewen | So my assumption is there's something in the (huge) litex update which broke TinyFPGA BX, and wasn't sufficiently compensated. | 03:00 |

| ewen | mithro: Thanks for the pointer. Curiously it seems like the iceBreaker *does* work, so my guess is there's something changed in the iceBreaker gateware, but not in the other two (and/or some relevant hardware differences). | 04:44 |
| mithro | ewen: You have an icebreaker? | 04:45 |
| mithro | ewen: Do you have a Fomu? | 04:46 |
| ewen | With me I have: TinyFPGA BX, iceBreaker, Fomu EVT2/3, Fomu PVT, Arty, and Mimas V2 | 04:50 |
| ewen | (I've had MicroPython running on TinyFPGA BX / iceBreaker / Arty / Mimas V2 before; not on the Fomus.) | 04:50 |
| ewen | FWIW, iceBreaker changes in litex-buildenv seem very similar to the TinyFPGA BX ones (memory region type). So maybe one of them is/was accidentally working before. | 04:51 |
| mithro | Does the arty work? | 04:52 |
| mithro | Just working on a talk for tomorrow | 04:53 |
| ewen | I'll give the Arty a try. | 04:53 |
| mithro | ewen: I think it is two things -- the SPI Flash controller and the new memory region stuff | 04:53 |
| mithro | ewen: The Arty has the BIOS embedded in the gateware rather than executing directly from SPI flash | 04:54 |
| ewen | mithro: Yes, the changes I can see are for the memory regions. | 04:56 |
| ewen | mithro: It's possible that the SPI Flash controller is related to the issue. | 04:56 |
| ewen | mithro: Seems like my Arty build is broken (Vivado runs start_gui). | 04:56 |
| ewen | (Looks like it's almost exactly two years since I installed Vivado, which is possibly related.) | 04:57 |
| ewen | (Xilinx license web page claims the licenses still exist, and seem to be the same as what I've got on my system. So I'm unclear what's triggering start_gui when I run "make gateware" :-( ) | 05:12 |
| mithro | :-/ | 05:20 |
| mithro | ewen: By the end of this year, you won't need to use Vivado any more :-P | 05:20 |
| ewen | :-) | 05:22 |
| ewen | mithro: I'm not having much luck figuring out how vivado is being invoked, let alone what's causing start_gui to be the thing invoked. | 05:22 |
| mithro | ewen: Did you see - https://github.com/xobs/wishbone-utils/issues/3 ? | 05:23 |
| tpb | Title: Support bash tab completion · Issue #3 · xobs/wishbone-utils · GitHub (at github.com) | 05:23 |
| mithro | ewen: And also have you done the Fomu workshop recently? workshop.fomu.im ? | 05:23 |
| ewen | I've done bits of that Fomu workshop recently (with PVT), but not all of it | 05:28 |
| ewen | wishbone-tool tab completion looks handy :-) | 05:29 |
| ewen | (Unfortunately it seems like it's impossible to build gateware for arty with detached head -- version_data.sh git command fails -- so I can't even test that.) | 05:29 |
| mithro | ewen: Look at build/XXXX/gateware/top.sh for the thing which runs vivado... | 05:33 |
| mithro | ewen: https://workshop.fomu.im got a facelift and a bunch of improvement for CCC | 05:34 |
| mithro | ewen: There is also a new rust stuff | 05:40 |
| mithro | ewen: And the new bootloader is *much* faster | 05:41 |
| ewen | mithro: Yes, I came back to the Fomu workshop when you were doing the 36c3 draft, so I did some of your version and some of xobs's version (mostly where examples were missing due to formatting issues). | 05:58 |
| ewen | mithro: Thanks for the gateware/top.sh hint, I'll see if I can figure out what it's trying to run at that point. | 05:58 |
| xobs | Also handy if you want to manually run things to avoid a lengthy rebuild. | 05:59 |
| ewen | mithro: Looks like build_top.sh runs "vivado -mode batch -source top.tcl".... so for some reason that batch build isn't running in batch mode. | 06:01 |
| ewen | mithro: Aha. I think that was self inflicted. I had a /usr/local/bin/vivado wrapper script, which didn't have "$@" in the "real vivado" it ran.... | 06:13 |
| ewen | (... so it was always running vivado without arguments. I'm assuming PATH changes meant that wasn't previously being hit via the litex-buildenv scripts...) | 06:15 |
| deeprave | howdy, i'm trying to flash an opsis board following the wiki, but getting: | 06:28 |
| deeprave | Info : JTAG tap: xc6s.tap tap/device found: 0x44028093 (mfg: 0x049 (Xilinx), part: 0x4028, ver: 0x4) | 06:28 |
| deeprave | Error: Unknown flash device (ID 0x00ffffff) | 06:28 |
| deeprave | Do I need to change jumpers on the board? I recall having to do so at LCA2017 (?) but I think that was for the other board type. | 06:28 |
| ewen | mithro: FYI, MicroPython on arty *does* work (CPU=lm32, latest litex-buildenv) | 06:32 |
| ewen | mithro: See also above from deeprave, which I'm assumimg is AV Team install issues. | 06:32 |
| deeprave | yeah, actually troubleshooting, but will need to do a load/test cycle to figure the issues out | 06:34 |
| mithro | deeprave: There is a page somewhere about that | 06:34 |
| mithro | deeprave: Basically if it has never been flashed before it will need a special process for the first time to flash | 06:34 |

| tpb | Title: Flashing Firmware · timvideos/HDMI2USB Wiki · GitHub (at github.com) | 06:37 |
| ewen | mithro: Is that the page you were thinking of? ^^^ | 06:37 |
| ewen | Carl confirms those are the instructions. And with Carl's help we have the HDMI2USB flashing working (at least on one device) | 06:51 |
| deeprave | so what CPU do I need to set for these (LCA) opsis boxes? | 07:03 |
| deeprave | i think that's the issue now, need to build the correct image | 07:03 |
| ewen | CPU default now seems to be vexriscv (RISC-V). I'm not sure if that's ever been tested with HDMI2USB. | 07:11 |
| ewen | The older CPU default was either lm32 or or1k, I forget which. (export CPU=.... is the override) | 07:12 |
| tumbleweed | we've used lm32 in the past, yes | 07:13 |
| ewen | deeprave: Based on above, I think try building with "export CPU=lm32" first, and see if that helps. | 07:15 |
| tumbleweed | also, master has been broken for around a year: https://github.com/timvideos/HDMI2USB-litex-firmware/issues/465 | 07:15 |
| tpb | Title: encoder broken: JPEG file: starts with 0x15 0x0c · Issue #465 · timvideos/HDMI2USB-litex-firmware · GitHub (at github.com) | 07:15 |
| ewen | tumbleweed: Thanks for the link. I think that's more subtly broken than where deeprave is currently stuck, so trying CPU=lm32 is likely to get closer to previously working config. | 07:16 |
| deeprave | CPU=lm32 (tried that first) but the enter script complains about not having a supporting build toolchain | 07:17 |
| deeprave | so lm32 is the correct one for the spartan6? | 07:18 |
| ewen | deeprave: You'll need to do "export CPU=lm32; scripts/download-env.sh" to get it to download the right tools. | 07:18 |
| deeprave | ah, kk | 07:19 |
| ewen | deeprave: The download-env.sh script tries to just download what it thinks is needed (thus makes the same CPU assumptions...) | 07:19 |
| ewen | deeprave: I've also been able to build HDMI2USB from source now (helped I had most of the FPGA tools already installed), so I'll try the same thing. | 07:19 |
| deeprave | awesome the script is downloading the correct toolchain now | 07:21 |
| mithro | I'm heading to bed | 07:45 |
| mithro | ewen: Wish I could be doing micropython hacking with you -- but should have some exciting things to share at LCA | 07:47 |
| ewen | mithro: It's all good. It sounds like your week is for a good cause :-) | 07:47 |

| mithro | Thanks! Good night everyone! | 07:53 |
| ewen | deeprave: I've got as far as the point you got stuck now (JTAG flashing not working). I have a feeling that's udev rule related. | 07:56 |
| deeprave | yep, Unknown flash device (ID 0x00ffffff) | 07:57 |
| ewen | In my case: Error: Unknown flash device (ID 0x00818181) | 07:57 |
| ewen | But it feels like "not getting valid data, making wild assumptions" :-) | 07:57 |
| deeprave | yeah string of jtag issues. but i did find that the hdmi2usb-mode-switch may be the problem | 07:58 |
| deeprave | installed separately via apt i just managed to upload a built image | 07:59 |
| deeprave | that is outside enter-env.sh, just used the apt installed version with hdmi2usb-mode-switch -v --flash-image <path to image> | 08:01 |
| ewen | deeprave: FWIW, I'm on Ubuntu 18.04 LTS (Bionic). So it's possibly not the same hdmi2usb-mode-switch. | 08:01 |
| ewen | (I'm also wondering if I'm going to have to reboot to get udev rules loaded properly...) | 08:01 |
| mithro | The unknown flash ID issue is caused by the default image turning on QSPI mode to the flash | 08:02 |
| ewen | Is there a work around? | 08:02 |
| mithro | Yes | 08:02 |
| ewen | ? | 08:02 |
| mithro | And there is totally a document somewhere which tells you how | 08:03 |
| ewen | :-) | 08:03 |
| ewen | I suggest you go to sleep. We'll try to find it :-) | 08:03 |

| mithro | Really really going to bed now | 08:06 |
| ewen | Thanks! | 08:07 |
| ewen | FTR, that "Unkown Flash Device" is for an Digilent Atlys; the board I'm having trouble with is a Numato Opsis. (My guess is that JTAG to the USB just isn't detecting it, possibly due to udev rules not being applied.) | 08:09 |
