| mithro | shenki: I brought my miniSpartan6+ into work today. Will have a play and see if I can repo. | 00:25 |
|---|---|---|
| mithro | shenki: Can you delete some of the branches in your repository that you don't need? | 00:26 |
| shenki | mithro: ok | 00:40 |
| shenki | mithro: you want the ms6 branch | 00:40 |
| mithro | shenki: I'm think going to rebase your ms6 stuff onto master without the or1k stuff so we can merge that sooner? | 00:41 |
| shenki | if you want | 00:41 |
| shenki | hang on, give me a sec | 00:41 |
| shenki | i havne't pushed the latest | 00:41 |

| shenki | mithro: when are you going to merge the or1k patches? | 01:11 |
| shenki | mithro: some of the cleanups there are good | 01:14 |
| mithro | shenki: no idea | 01:33 |
| mithro | shenki: also have to merge the opsis-timing branch too | 01:33 |
| shenki | mithro: ok. i will buy a power supply for my opsis today, and test the branches on there tonight | 01:35 |
| shenki | mithro: if the hdmi functioanltiy still works, I suggest we merge them in? | 01:36 |
| shenki | no need to waste your cycles maintaining a branch | 01:36 |
| mithro | shenki: That is a good question, I haven't really done any extensive testing | 01:36 |

| cr1901_modern | mithro: pong (just woke up) | 07:45 |
| mithro | cr1901_modern: trying to get the spi flash working on the minispartan6+ | 07:49 |
| mithro | cr1901_modern: I'm assuming you haven't done anything with that so far? | 07:49 |
| cr1901_modern | You mean in terms of a the CPU using it as the ROM address space, or just "storing the bitstream" | 07:50 |
| mithro | cr1901_modern: as in using it for storage, yes | 07:50 |
| cr1901_modern | No, I didn't get that far yet. A bit curious it doesn't work "out of the box" though | 07:50 |
| mithro | cr1901_modern: have you had any experiance with it before? | 07:55 |
| mithro | at the moment I'm just having trouble getting it to read anything resembling the stuff I've used openocd to write too | 07:55 |
| mithro | ooooo - I think it almost just worked on the Atlys.... | 07:57 |
| cr1901_modern | Well, I have gotten a bitstream to successfully write to the flash. | 07:57 |
| cr1901_modern | mithro: I do remember having some trouble initially writing to the device at all. Right now, my minispartan6+'s flash has the Migen blinky code on it. | 08:00 |
| _florent_ | mithro: if you need help with the SPI flash I can have a look (just need to know what code you are testing) | 09:08 |
| mithro | Well, I've gotten the spi flash to work on the Atlys board | 12:06 |
| mithro | Turns out that I was putting the SPI flash and LiteEth at the same memory location on that board | 12:08 |
| mithro | _florent_: Why do you do " self.add_memory_region("ethmac", self.mem_map["ethmac"]+self.shadow_base, 0x2000)" ? | 12:10 |

| mithro | shenki: I'm unsure how to get the values out of the targets file needed for the openocd flash command | 13:31 |
| mithro | shenki: can you try and repo this work when you get a chance | 13:39 |
| CarlFK | mithro: I am going to try vocto with atlys and opsis - lightning talks at ps1 in 11 hours | 13:56 |
| _florent_ | mithro: I'm doing the self.add_memory_region just to define the region. It's probably only used to generate the mem.h | 13:56 |

| shenki | eww, hat didn't paste so well | 14:33 |
| shenki | sorry | 14:33 |
| mithro | shenki: who is that with? | 14:35 |
| *** rohitksingh has joined #timvideos | 14:36 | |
| mithro | The firmware freezes after the version info is output. But I think that is because of something in the C code | 14:37 |
| shenki | mithro: uniti | 14:37 |
| _florent_ | mithro, I'm sure I used to know but I don't remember now | 14:37 |
| shenki | mithro: wireless (wifi) isp in adelaide | 14:37 |
| mithro | _florent_: ha :-P | 14:38 |
| mithro | What is with the shadow stuff? Is that too avoid the l2 cache or something? | 14:39 |
| mithro | shenki: I didn't test serialboot | 14:40 |
| _florent_ | sb0: do you remember why we have the "| 0x80000000" when declaring the memory_region? | 14:40 |
| mithro | shenki: but it's kind of nice that you can just flash new firmware without rebuilding the gateware | 14:42 |
| *** CarlFK has quit IRC | 14:43 | |
| cr1901_modern | Incidentally, we definitely access CSR peripherals in the shadow region instead of their real addresses... | 14:44 |
| mithro | Next thing to get working on the minispartan is the HDMI output | 14:46 |
| shenki | mithro: nice | 14:47 |
| shenki | well, for me it's getting some more complicated software booting | 14:47 |
| shenki | like the kenrel | 14:47 |
| shenki | mithro: how much flash do we have? | 14:47 |
| mithro | I put it in a comment somewhere | 14:48 |
| cr1901_modern | According to _florent_, the minispartan's SDRAM speed is bad, so we're only gonna get like 640x480 HDMI output | 14:48 |
| *** CarlFK has joined #timvideos | 14:48 | |
| *** ChanServ sets mode: +v CarlFK | 14:48 | |
| _florent_ | maybe more with YCBCR 4:2:2 | 14:48 |
| cr1901_modern | _florent_: Did you do theoretical calculations? | 14:49 |
| mithro | I wonder if we can over clock :-P | 14:49 |
| cr1901_modern | Probably... | 14:49 |
| _florent_ | what the frequency of the ms6 SoC? | 14:50 |
| cr1901_modern | 80 MHz, but I meant simply at the max speed the SDRAM supports, which is 133MHz? | 14:51 |
| mithro | 80 MHz | 14:51 |
| mithro | Having a 640*480 development device that fits in your pocket ain't bad | 14:52 |
| mithro | shenki: pretty sure you should be able to fit a Linux kernel and small initrd | 14:53 |
| mithro | Enough to get the SD card up and running | 14:53 |
| _florent_ | OK so we should have around 1Gbps of bandwidth on the SDRAM | 14:53 |
| shenki | mithro: k | 14:53 |
| _florent_ | 1280x720@30fps is 442Mbps with ycbcr4:2:2 | 14:53 |
| cr1901_modern | 640*480 is enough for anything I want to do with HDMI (old CRT emulation) | 14:54 |
| _florent_ | so it should be enough for in and out | 14:54 |
| mithro | Does uboot add anything? | 14:54 |
| shenki | no | 14:54 |
| * shenki us currently doing a uboot upstream for the aspeed | 14:54 | |
| shenki | our "uboot" is the bios | 14:55 |
| sb0 | _florent_, to disable cache | 14:55 |
| _florent_ | sb0: ok thanks! | 14:55 |
| mithro | _florent_: any reason not to do 420 rather then 422? | 14:57 |
| mithro | sb0: from what I can see - with the spi flash you could execute directly from it (but probably quite slowly?) and that is what happens when using the BIOS in spi flash? | 14:59 |
| mithro | shenki: this was only the lm32 not the or1k btw | 15:04 |
| mithro | Anyway bed time | 15:05 |
| mithro | Good night everyone. | 15:05 |

| xfxf | mithro: on Mar 16, 2016 you put a post up on hdmi2usb.tv that said "A further backer update will be released within 30 days with more information." | 16:10 |
| xfxf | has this been done? if not, a reminder :) | 16:10 |
| xfxf | (re the HDMI cable/amp issue) | 16:10 |
| CarlFK | xfxf: hey! ... any idea how to load updated firmware into the Opsis? | 16:13 |
| xfxf | not something i've done since LCA, sorry | 16:13 |
| CarlFK | did you even do it? | 16:13 |
| xfxf | i did, yeah | 16:13 |
| xfxf | i even patched the firmware | 16:13 |
| xfxf | one or two bytes of change | 16:13 |
| xfxf | woo | 16:13 |
| CarlFK | I never even watched. any idea where I should look for clues? | 16:13 |
| xfxf | i don't recall off the top of my head | 16:14 |
| CarlFK | yeah, I want that patch | 16:14 |
| xfxf | oh the gamma one? | 16:14 |
| CarlFK | yes | 16:14 |
| xfxf | right | 16:14 |
| CarlFK | well, i want to know how to put it on the Opsis | 16:14 |
| xfxf | oh, i was going to say, i was going to just look at the bash history on the laptop i did it on | 16:14 |
| xfxf | but i no longer own it | 16:14 |
| xfxf | (i sold it and bought an i7 thinkpad yoga) | 16:14 |
| xfxf | i'm meant to be recording an event tomorrow so it's something i am going to be looking at in the next ~16 hrs | 16:15 |
| xfxf | but about to go to bed (2am here) | 16:15 |
| CarlFK | I have 3 or 4 tabs open around here that mithro pointed me at ... but none looked very.. useful ;/ | 16:15 |
| xfxf | i remember you had to put the thing into a different mode to flash it | 16:15 |
| CarlFK | lol - am going to be doing some hackerspace lightning talks in 8 hours... | 16:15 |
| xfxf | memory fuzzy, sorry | 16:15 |
| CarlFK | so any few moments you can give me once you wake up.. I know.. jobs and all | 16:16 |
| xfxf | i won't remember much until i attempt again | 16:16 |
| xfxf | i'll likely try tomorrow morning | 16:16 |
| xfxf | i.e. in ~8-10 hrs | 16:16 |
| CarlFK | that would be great - | 16:16 |
| xfxf | which doesn't help you sorry :( | 16:16 |
| CarlFK | yeah, you wake up about the time talks start | 16:17 |
| CarlFK | no biggie | 16:17 |
| CarlFK | it is more to test vocto | 16:17 |
| xfxf | did you see the gsoc proposal for hardware mixing? | 16:18 |

| CarlFK | mithro: any chance it will mess things up? | 23:00 |
| mithro | CarlFK: that should mean we have a "make flash" in the makefile | 23:00 |
