| felix_ | one moment; i'll make a pull request for that | 00:01 |
|---|---|---|
| shenki | okay | 00:04 |
| shenki | so when I do this step, it gives me the "failed to identify flash" message: | 00:04 |
| shenki | jtagspi_init 0 {third_party/flash_proxies/bscan_spi_xc7a35t.bit} | 00:04 |
| shenki | Error: Unknown flash device (ID 0x00ffffff) | 00:05 |
| felix_ | you have the spi proxy bitstreams on your machine? iirc they aren't shipped within openocd | 00:05 |
| shenki | yeah, i do | 00:10 |
| shenki | mithro ships them as part of the litex environment we use | 00:10 |
| shenki | it comes from https://github.com/jordens/bscan_spi_bitstreams | 00:11 |
| tpb | Title: GitHub - jordens/bscan_spi_bitstreams (at github.com) | 00:11 |
| felix_ | made a pull request for that; would be good if someone could verify that this doesn't break anything (it shouldn't, but i don't have an arty here to test) https://github.com/timvideos/conda-hdmi2usb-packages/pull/23 | 00:17 |

| felix_ | upstreaming that would be best, but the openocd people seem to be quite slow with looking at patches; i submitted openocd support for the ac701 maybe three weeks ago and still didn't get any response or review | 00:19 |
| mithro | See also -> http://openocd.zylin.com/#/c/4156/ | 00:22 |
| tpb | Title: Gerrit Code Review (at openocd.zylin.com) | 00:22 |
| mithro | felix_: I've found the best way is to join #openocd and poke PaulFester to get stuff reviewed | 00:23 |
| shenki | mithro: how do we debug the failure to identify flash? | 00:24 |
| mithro | shenki: Not sure... | 00:24 |
| mithro | shenki: Sorry, have stuff I need to be doing... | 00:24 |
| felix_ | the patch on the openocd gerrit misses the spi flash programming include | 00:24 |
| felix_ | mithro: ok, thx; i put that on my todo list | 00:25 |
| felix_ | currently packing the stuff i need for the hackathon in vienna | 00:26 |
| mithro | This year is disappearing soooooo fast.... | 00:32 |
| mithro | felix_: Do you have an Arty A7 board? | 00:37 |
| *** CarlFK has quit IRC | 00:37 | |
| felix_ | no | 00:39 |
| *** shorne_ has joined #timvideos | 00:40 | |
| felix_ | i currently have a zybo, an ac701, an icoboard, a pipistrello, some custom fpga board and maybe some old fpga boards i don't remember exactly (maybe spartan 3 and virtex 4) | 00:41 |
| felix_ | ah and one trenz artix7 micromodule with base board | 00:42 |

| tpb | Title: arty: add csr for cpu_reset · shenki/HDMI2USB-misoc-firmware@a426189 · GitHub (at github.com) | 00:48 |
| mithro | shenki: What happens? | 00:49 |
| mithro | shenki: Nothing or the system locks up? | 00:50 |
| shenki | nothing | 00:50 |
| mithro | shenki: Can you test by using bios mr command? | 00:50 |
| shenki | i can try that. i was using devmem from userspace which does the same thing | 00:51 |
| shenki | oh. that made the console print lots of "ef bf bd ef" | 00:57 |
| shenki | and then it hung | 00:57 |

| *** wcmckee has quit IRC | 01:01 | |
| shenki | that's not what i'm after | 01:02 |
| shenki | i want it to reboot the cpu :) | 01:02 |
| mithro | shenki: You need to do something a little bit more advanced because doing the reset causes the clock to go away which means you never come out of reset... | 01:02 |
| shenki | okay | 01:03 |

| shenki | mithro: what does 'git describe' say? | 01:26 |
| mithro | shenki: It's in a random email from kbuild-test-robot | 01:26 |

| shenki | if you haven't committed it, then generate it with `diff -up` | 01:30 |
| shenki | but i recommend committing it :) | 01:30 |
| felix_ | ok, will do. have to get some sleep now though to be awake when i have to catch my train to the airport | 01:31 |

| shorne_ | shenki: I will start looking at the patches for evbar | 06:41 |
| shenki | shorne_: cool | 06:42 |
| shorne_ | as per mithro's mail updates for: networking, evbar patches, next steps... | 06:42 |
| shorne_ | Is there anything you want me to take over? | 06:42 |
| shenki | let me check the email | 06:43 |
| shorne_ | I have been busy the last few days/weeks with gdb upstreaming (or1k port is upstream now) and the uclibc fixes | 06:43 |
| shenki | shorne_: congrats on the gdb upstreaming work! | 06:43 |
| shenki | shorne_: there are a few things in head.S we need to fix for litex support | 06:48 |
| shenki | shorne_: one is using evbar for saving registers | 06:48 |
| shenki | shorne_: another changing the way the uart is used in head.S | 06:49 |
| shenki | shorne_: the options there would be to write a driver for the litex uart, and use that when we're on a litex platform | 06:49 |
| shenki | shorne_: the other is to remove the use of it from the assembly, and rely on a C driver | 06:49 |
| shenki | do you have thoughts? | 06:49 |
| shorne_ | shenki: thanks on gdb its been a long work in progress | 07:13 |
| shorne_ | on uart, I am fine removing in head.S, usually thats just there for some really early time debugging | 07:14 |
| shorne_ | its just edited when needed | 07:14 |
| shorne_ | Is it needed/used in litex? | 07:14 |
| shenki | shorne_: i don't think it's required. need to double check | 08:12 |

| cr1901_modern | mithro: the enter-env.sh needs work detecting the python version. On my machine "python" is for python 2, not python 3 | 16:23 |
| cr1901_modern | I'm not sure how to proceed considering I almost never use enter-env, and I'm only doing so b/c I suspect I broke travis by not assuming enter-env.sh was run | 16:23 |
| cr1901_modern | mithro: Disregard, I didn't follow directions | 16:28 |
| cr1901_modern | Actually, maybe not. Do you support either running from conda or your distro-provided python? | 16:30 |
| *** samsagaz has joined #timvideos | 16:36 | |
| *** rohitksingh has quit IRC | 16:43 | |
| *** rohitksingh has joined #timvideos | 16:44 | |
| mithro | cr1901_modern: no | 17:21 |
| mithro | cr1901_modern: we only support running inside of the conda environment... | 17:21 |
| cr1901_modern | mithro: I see. Well in any case, that wasn't the issue | 17:22 |
| cr1901_modern | mithro: Check #j-core for what the real issue was, since I asked resident Unix expert dalias a question about what I was seeing in travis | 17:22 |
| cr1901_modern | Okay _finally_ the travis builds (except for arty so far) are passing | 17:27 |
| cr1901_modern | (and it's a missing #ifdef, so that's simple enough) | 17:28 |
| cr1901_modern | https://travis-ci.org/timvideos/HDMI2USB-litex-firmware/jobs/316532852#L3783 | 17:28 |
| mithro | How hard is it to avoid the meson dependency until we use meson for everything? | 17:29 |
| cr1901_modern | Difficult. | 17:30 |
| mithro | Or an alternative question, how hard would it to be to convert our makefile + scripts/xxxx-env.sh into meson? | 17:30 |
| cr1901_modern | that would also be a bit of work (but it would make things a lot cleaner when its done) | 17:31 |
| cr1901_modern | I don't see you getting around scripts/xxx-env.sh tho | 17:32 |
| cr1901_modern | perhaps talk to jpakkane and see what he thinks? | 17:33 |
