| olofk | Hmm... looks like the UART functions in our libgloss port aren't very well suited for adding additional uarts | 10:44 |
|---|---|---|
| olofk | Do we really need our own uart16550 driver in libgloss? Isn't that a standardized interface? | 11:00 |
| juliusb | yes, that's a fair hack our libgloss UART support | 11:10 |
| juliusb | You can blame me for most of that | 11:10 |
| juliusb | Not sure if the register interface is the same as another one, probably is? | 11:10 |
| olofk | I think that's the point of uart16550, but I'm not sure | 11:13 |
| olofk | Another thing. How the hell do you add a new contact to gmail? I only get the option to add to my (google+?) circles | 11:14 |
| stekern | in contacts? | 11:15 |
| olofk | yes | 11:15 |
| olofk | Ohh.. missed the big red plus sign :) | 11:16 |
| olofk | How do I manage to lose my old orconf slides EVERY YEAR?!?!? | 12:22 |
| olofk | I can only find those from 2012 | 12:23 |
| juliusb | olofk: they're not on a site somewhere? | 13:25 |
| olofk | I guess they should have been. We've not been that good at collecting slideshows over the years | 13:27 |
| mafm | blueCmd: are you going to orconf? will you present something about the debian port? | 13:55 |
| blueCmd | mafm: I'm going but no, nothing to present this orconf. Hopefully we can resume our GCC upstreaming efforts soon if we can solve our indifferences with the last GCC contributor | 13:57 |
| blueCmd | which reminds me, I need to print the assignment documents | 13:57 |
| blueCmd | oh, I had already done that | 13:58 |
| mafm | :) | 13:58 |
| mafm | more than 1 year has gone by already... | 13:59 |
| mafm | btw, if anybody is looking for a job, maybe this is of interest: http://www.esa.int/hr/PDF/ESA-VN-ESTEC-2015-046,REV.1.pdf | 13:59 |
| blueCmd | mafm: I know, time flies | 14:00 |
| * mafm looking for a job, but doesn't know about FPGAs... must be the only one in this channel :P | 14:02 | |
| blueCmd | mafm: nah, there are other people who are focusing on the software part :) | 14:02 |
| mafm | also, risc-v fork is not upstreamed either, I think | 14:03 |
| robtaylor | mafm: yeah, risc-v needs upstreaming love | 16:05 |
| robtaylor | mafm: there's no reason for it not to be cleaned up and patches started to be send now, I think :/ | 16:05 |
| mafm | robtaylor: I poked people now and then in private, I think I even sent to the mailing list posts like a year ago... but... | 16:07 |
| olofk | But is the RISC-V ISA set now? IIRC there still were some details to be figured out | 16:07 |
| mafm | based on the experience of openrisc and our little Debian port, it's a real problem | 16:07 |
| olofk | Oh well. Guess we'll know tomorrow :) | 16:07 |
| mafm | olofk: I guess that they could start submitting it, doesn't need to stay fixed over time | 16:08 |
| mafm | in fact, upstream will probably require several iterations before accepting the ports | 16:09 |
| olofk | mafm: True. As we've seen with OpenRISC, it's best not to wait for too long | 16:09 |
| mafm | Krste says in talks that one of the big problems for developing new architectures is the high cost of the toolchain, I think that he mentions the figure of 1 billion USD | 16:09 |
| mafm | I don't know if the estimation is right, but sounds like one of the biggest problems indeed, and worth tackling it right from the start :-) | 16:10 |
| robtaylor | mafm: will you be at orconf by any chance? :) | 16:10 |
| robtaylor | mafm: the kernel guys have already *asked* for patches to start being submitted | 16:11 |
| mafm | esp. before the possible unfortunate case that some main developer gets hit by a bus :-/ | 16:11 |
| robtaylor | we might need to start doing it for the berkely guys | 16:11 |
| mafm | robtaylor: nope, tried to go but couldn't arrange it in the end, busy life and other pending travels at the moment | 16:11 |
| robtaylor | mafm: ah shame! | 16:12 |
| mafm | yeah I think that some Linux person mentioned that like 6 months ago in the lists, I think | 16:12 |
| robtaylor | not quite that long ago, a couple of months max.. | 16:12 |
| robtaylor | seems a long while though ;) | 16:12 |
| mafm | robtaylor: why do you ask, do you want to form a task force to convince them? :D | 16:13 |
| robtaylor | mafm: i'd happily start cleaning up their patcheset and upstreaming it for them... | 16:13 |
| robtaylor | (if I can allocate the time..) | 16:14 |
| mafm | robtaylor: I don't know if I would be able to do that, never got involved with toolchains before, but if you can it would be really nice | 16:15 |
| * robtaylor can do kernel stuff | 16:15 | |
| mafm | I considered it once or twice but my soon-to-be-ex-employers have funny ideas and rules about copyrights, so I didn't want to mess things around anyway | 16:16 |
| robtaylor | not done much GCC/binutils before but I don't think they're a particularly tricky community | 16:16 |
| GeneralStupid | Hi | 16:17 |
| mafm | hi | 16:18 |
| * mafm searching for the mailing list posts... | 16:18 | |
| mafm | I asked at least in Feb, and Reinoud also in Feb if support would be included in gcc 5.0 (he was overly optimistic, I guess :D) | 16:19 |
| robtaylor | off to meet with hesham | 16:21 |
| robtaylor | ttfn :) | 16:21 |
| mafm | Arun thomas asked about upstreaming in Jul and Aug, then Arnd in early september (I think that he's a Linux developer) | 16:26 |
| mafm | but I seem to remember to read some advice from upstream devels even before that | 16:26 |
| mafm | anyway, you ppl @ orconf poke them about that, please :) | 16:26 |
| olofk | mafm: Consider them poked! :) | 16:30 |
| mafm | thanks olofk ! | 16:31 |
| -!- orsonmmz is now known as orsonmmz|away | 16:39 | |
| GeneralStupid | Hi, i need some quick informations... I try to get my testproject working "quick and dirty" | 17:26 |
| GeneralStupid | because of a presentation i had to do | 17:26 |
| GeneralStupid | i forget how i could "synchronize" the wishbone bus | 17:34 |
| GeneralStupid | hmmm | 18:28 |
| GeneralStupid | i get jtag errors | 18:28 |
| jeffesquivels | EHLO | 20:13 |
| jeffesquivels | mafm: I used FPGAs briefly during college (more than a decade ago)... but haven't since | 20:13 |
| jeffesquivels | I'm trying to re-learn everything now | 20:13 |
| olofk | GeneralStupid: Synchronize.. such as doing a clock domain crossing? | 20:14 |
| GeneralStupid | what did i write? :/ | 20:14 |
| GeneralStupid | synchronize like generating the vhdl files without rebuildung the whole core | 20:15 |
| olofk | It's sppoky to get a mail that says @OlofKindgren is now following you on twitter | 20:21 |
| olofk | Realized it was another twitter account that I'm registered to as well :) | 20:21 |
| GeneralStupid | twitter :-D | 20:22 |
| olofk | GeneralStupid: Regenerate from what? | 20:22 |
| GeneralStupid | from the wb_interconnect.conf | 20:22 |
| olofk | aha | 20:22 |
| olofk | Well, in that case no | 20:23 |
| andrzejr | So, instead of showing off Linux running on nexys4 tomorrow, I may ask some of you to help me debug it. :-) | 21:03 |
| andrzejr | my "last result" solution (slowing down clocks (266MHz to 200MHz and 66MHz to 50MHz) which simplifies clocking in the DDR2 ctrl) didn't work - still getting these "random" freezes when booting Linux. | 21:05 |
| andrzejr | *last-resort | 21:06 |
| _franck_ | andrzejr: does it works when running uboot or barebox ? | 21:07 |
| _franck_ | if not, has they are smaller than Linux it could be easier to find what's going wrong | 21:08 |
| GeneralStupid | i need to ask a question where i maybe already know the answer... | 21:14 |
| andrzejr | _franck_, good idea. I haven't tried them yet (newlib apps were working so I assumed HW is fine) | 21:14 |
| GeneralStupid | The offset in the WB config... what limits it? | 21:14 |
| andrzejr | GeneralStupid, total memory size and size of the slave's address space | 21:19 |
| GeneralStupid | andrzejr: total memory depends on my onboard memory | 21:24 |
| GeneralStupid | andrzejr: where can i see the slave's address space? | 21:24 |
| GeneralStupid | i'm so sure that it worked in that configuration.... | 21:24 |
| andrzejr | The "size" parameter. offset+size-1 should not overflow the offset value. | 21:29 |
| GeneralStupid | andrzejr: thats what you meant, no thats no problem :-D | 21:30 |
| GeneralStupid | i cannot 'access' to the led's | 21:31 |
| andrzejr | show me your wb_intercon.conf | 21:31 |
| GeneralStupid | its late here , ok ?:-D | 21:32 |
| GeneralStupid | https://dpaste.de/Lhhr | 21:32 |
| GeneralStupid | its called ledr0, i only have 8 Mb of memory... i think its too big | 21:33 |
| GeneralStupid | no, wait, not possible. Because of slave rom0 , i did not change that | 21:34 |
| andrzejr | That looks OK to me. Are you accessing ledr0 with l.sb and l.lbz? There are some bugs which may cause problems with 16b/32b access. | 21:41 |
| mafm | jeffesquivels: me not even that, I never really touched fpgas :-S | 22:12 |
