| cr1901_modern | mithro: Is the timvideos openocd tied to any specific commit? | 13:34 |
| cr1901_modern | I compiled a fresh openocd for the board my opsis is attached to, and I couldn't program the opsis until I swapped out the old bitstream proxy: https://github.com/timvideos/HDMI2USB-mode-switch/tree/master/hdmi2usb/firmware/spartan6/opsis for the new one: https://github.com/quartiq/bscan_spi_bitstreams/blob/master/bscan_spi_xc6slx45t.bit | 13:36 |

| mithro | cr1901_modern: Interesting - do we just need to update a submodule somewhere? | 21:40 |
| mithro | cr1901_modern: Oh - we had a slightly custom proxy a while back on the Opsis | 21:41 |
| mithro | cr1901_modern: I think the change we needed might have been merged upstream now | 21:41 |
| cr1901 | mithro: If it's a custom proxy, it's not compatible w/ how rjo updated the jtagspi backend semi-recently | 21:43 |
| mithro | cr1901_modern: (Basically it held unused pins in a different way - I think in high impedance...) | 21:43 |
| cr1901 | The current proxies have pullups on the unused pins | 21:44 |
| mithro | cr1901: Can't remember which way they need to be... | 21:46 |
| mithro | cr1901: If the upstream proxies work, then it is all good I think? | 21:46 |
| cr1901 | mithro: The upstream proxies worked for me; the proxy that's provided w/ mode switch does not. >> | 21:47 |
| cr1901 | Which makes me think that if the mode-switch bitstream is custom it's based on rjo's old proxies: https://github.com/jordens/bscan_spi | 21:49 |
| mithro | cr1901: Hrm... on windows or on any platform? | 21:49 |
| tpb | Title: GitHub - jordens/bscan_spi: A JTAG-to-SPI converter for building spi-flash proxy bitstreams for FPGAs (at github.com) | 21:49 |
| mithro | cr1901: They are in fact based on those | 21:49 |
| cr1901 | mithro: I tested on a Linux SBC | 21:49 |
| cr1901 | If you read the warning, rjo points to a new repo, with a new set of proxies. Upstream openocd is expected to use the proxies on the master branch | 21:50 |
| cr1901 | And since I compiled a fresh openocd today (b/c "accident"), I ran into this issue w/ mode-switch where the proxy didn't work at all; the flash id returned 0x00ffffff | 21:51 |
| cr1901 | Okay here we go: https://github.com/quartiq/bscan_spi_bitstreams Looks like the bitstreams were all updated 6 months ago | 21:52 |
| tpb | Title: GitHub - quartiq/bscan_spi_bitstreams (at github.com) | 21:52 |
| mithro | cr1901: Wonder why we haven't come across this sooner... | 21:53 |
| cr1901 | mithro: This is why I'm asking you if the conda openocd is pinned to a specific commit | 21:53 |
| mithro | I guess it must be? | 21:54 |
| cr1901 | B/c it seems like I'm the only person w/ this issue and the only difference is that I compiled a fresh openocd (and used hdmi2usb-mode-switch outside of conda env) | 21:54 |
| cr1901 | Naturally, not the first time I've had this issue :). That's why I knew what was wrong immediately | 21:55 |
| mithro | cr1901: https://github.com/timvideos/conda-hdmi2usb-packages/blob/master/openocd/meta.yaml | 21:58 |
| tpb | Title: conda-hdmi2usb-packages/meta.yaml at master · timvideos/conda-hdmi2usb-packages · GitHub (at github.com) | 21:58 |
| mithro | cr1901: It doesn't look to be pinned | 21:58 |
| cr1901 | very weird... | 22:08 |
| cr1901 | I'll have to ask rjo what changed | 22:10 |
