| xiangfu | lekernel: all the code is ready for RC3 right? | 02:06 |
|---|---|---|
| xiangfu | if the code is ok, I will trigger one build for Adam. (for RC3 boards) | 02:07 |
| xiangfu | ok. it already there. :) | 02:08 |
| xiangfu | http://www.milkymist.org/updates/2011-07-13/ | 02:08 |
| kristianpaul | he, sozi is nice | 02:31 |
| kristianpaul | thanks rejon ! | 02:31 |
| aw | xiangfu, so i still should to use http://milkymist.org/wiki/index.php?title=Flashing_the_Milkymist_One#Flash_BIOS_with_mac_address to reflash each board, right? | 02:52 |
| xiangfu | yes | 02:52 |
| xiangfu | Hi from the http://www.milkymist.org/updates/2011-07-13/, it not reflash the data partition. | 02:53 |
| xiangfu | I would advice flash all patchpool and wallpaper to data partition. | 02:53 |
| xiangfu | no needs let user download patches manually | 02:53 |
| kristianpaul | aw: hi, already passed SMT? | 03:14 |
| kristianpaul | s/passed/done | 03:15 |
| aw | kristianpaul, hi, not yet finished SMT process. | 03:16 |
| aw | kristianpaul, supposedly be held on tomorrow, but still seems that they are still busy though. :-) Usually they notice me before one day. he. :-) | 03:18 |
| kristianpaul | :-) | 03:18 |
| lekernel | xiangfu, in updates/ it's for the auto web update and it does take care of the patch pool | 07:54 |
| xiangfu | yes. I mean when Adam reflash the RC3 board, we can just flash all patches to the boards. no needs let user webudpate again :) | 07:55 |
| lekernel | have you got my email? | 07:55 |
| lekernel | yes for the run 3 boards you flash the data partition of course | 07:56 |
| lekernel | you'll also need to modify my rescue BIOS image to take into account the different mac addresses | 07:56 |
| lekernel | well, everything should be explained in the email I sent yesterday | 07:56 |
| xiangfu | no. not check mail today. will read that later. | 07:56 |
| xiangfu | ok. thanks. | 07:56 |
| lekernel | xiangfu, you need to update the BIOS CRC after you modify the MAC address | 08:30 |
| xiangfu` | (CRC) lekernel_ oh, yes. | 09:56 |

| lekernel | ok i have some experimental rendering in 1027x768 | 20:43 |
| lekernel | 1024 | 20:43 |
| mwalle | hi | 20:47 |
| mwalle | cool ;) | 20:47 |
| lekernel | the problem is, I need to increase the soc frequency to 90MHz which isn't possible when CPU debugging is enabled (it wouldn't meet timing and the critical path goes through the debug unit) | 20:48 |
| mwalle | breakpoints unit? | 20:48 |
| lekernel | watchpoints | 20:50 |
| mwalle | so what do you think about building only the failsafe image with break/watchpoints | 20:51 |
| lekernel | mh... one of the nice things about the hw debugger is you can run it after an unexpected crash | 20:56 |
| mwalle | yeah but did you ever used watchpoints? | 20:56 |
| mwalle | (after a crash) | 20:56 |
| mwalle | btw is the spartan6 really that slow compared to the cyclone3? or are only the tools shitty? | 21:01 |
| lekernel | good question, I don't really know | 21:02 |
| lekernel | it'd be interesting to try with synplify, so at least the netlist would be good | 21:03 |
| lekernel | but I don't have access to any version that supports the s6 | 21:03 |
| lekernel | well.. maybe i'll use altera on my next board ;-) | 21:04 |
| lekernel | especially since they published a lot of stuff with QUIP with is a lot easier to understand than xdl/speedprint/fpgaeditor | 21:04 |
| mwalle | lekernel: enabling debug without watchpoints/hw breakpoints should still give you enough possibilities for debugging | 21:12 |
| wpwrak | how much faster would it get with altera ? | 21:27 |
| lekernel | difficult question | 21:37 |
| mwalle | wpwrak: accoring to terpstra 125mhz with cyclone 3 and 175 with aria2 (dunno the lm32 config) | 21:38 |
| lekernel | he, some patches look very nice in 1024 | 21:42 |
| lekernel | I cranked up the mesh size too (this we can do without difficulty, we have more than enough FPU power atm) | 21:42 |
| lekernel | the fps drops though ... | 21:43 |
| lekernel | % stats | 21:43 |
| lekernel | Uptime: 00:05:07 FPS: 10 CPU: 32% | 21:43 |
| lekernel | Net memory bandwidth : 1754 Mbps | 21:43 |
| lekernel | Memory bus occupancy : 44% | 21:43 |
| lekernel | Avg. mem. access time: 4.20 cycles | 21:43 |
| lekernel | i'd guess this could be solved with pixel prefetching in the TMU | 21:47 |
| wpwrak | mwalle: and with xilinx it's < 90 MHz ... so up to twice as fast. nice ! seems that the altera chips are also a bit more expensive than their xilinx counterparts, though (?) (e.g., XC6SLX45-2FGG484CES vs. EP3C40F484C8N, at digi-key USD 54 vs. 87) | 21:49 |
| mwalle | wpwrak: well <90mhz vs 125mhz, dunno what a virtex can achieve | 21:50 |
| lekernel | http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.22.3640&rep=rep1&type=pdf | 21:53 |
| lekernel | is the slx45 comparable to the 3c40, in terms of area? | 21:53 |
| lekernel | also the aria2 are very expensive | 21:54 |
| wpwrak | according to digi-key, EP3C40F484 has 39600 logic elements/cells (vs. 43661), 2475 LABs/CLBs (vs. 3411), and ~1 Mb RAM (vs. ~2 Mb), 484 BGA | 21:56 |
| wpwrak | if you need more RAM (and also some more logic), the next stop would be EP3C55, at USD 141+ | 21:57 |
| wpwrak | too bad there's no nice way to "export" a digi-key query | 21:58 |
