| lekernel | /* The core i2c driver will automatically retry the transfer if the | 14:16 |
| lekernel | * adapter reports EAGAIN. However, we find that bit-banging transfers | 14:16 |
| lekernel | * are susceptible to errors under a heavily loaded machine and | 14:16 |
| lekernel | * generate spurious NAKs and timeouts. Retrying the transfer | 14:16 |

| lekernel | ah, linux ... | 14:16 |
| Fallenou | ahah yes I saw that :) | 14:17 |
| Fallenou | i2c in linux has a few quirks | 14:17 |
| lekernel | ah and the nouveau driver loves broken DDCs. typically, it will disable the port until you reboot or suspend... | 14:27 |
| Fallenou | fantastic ! | 14:44 |
| _florent_ | Hi | 21:06 |
| _florent_ | just for info, after the de0 nano port | 21:06 |
| _florent_ | I'm starting working with milkymist-ng with the KC705 | 21:06 |
| _florent_ | Nothing very insteresting to say for the moment because nothing is tested yet... | 21:07 |
| _florent_ | but I'll tell you when it will start working | 21:07 |
| _florent_ | for the moment there won't be a DDR3 controller | 21:08 |
| _florent_ | but we will have to discuss about that if some design can be share with your future M^3 | 21:09 |
| lekernel | great :) | 21:10 |
| _florent_ | Hi lekernel | 21:19 |
| _florent_ | for info the LM32 seems to work at at least 156MHz on the kintex | 21:20 |
| _florent_ | I've tried 200MHz but I was having timings errors.... | 21:21 |
| _florent_ | 156 is probably not the max, but I haven't played with the mmcm for the moment | 21:21 |
| Fallenou | very nice :) | 21:31 |
| lekernel | hmm, weird, I'm quite sure I had 200 | 21:32 |
| lekernel | have you tried disabling some options (multipliers, divider ...) | 21:33 |
| _florent_ | in fact 200 was ok for the cpu alone | 21:40 |
| _florent_ | but it must be close to 200, I was only having small timings issues on the multiplier | 21:41 |
| _florent_ | haven't try without | 21:41 |
| _florent_ | On the kc705 I'm going to use the milkymist-ng frame buffer + some color conversion module + the ADV7511 on the board | 21:43 |
| _florent_ | Do you have developped some simple code to test the frame buffer on the ng? | 21:44 |
| _florent_ | If so I'll be interested to test the frame-buffer --> color conversion --> ADV7511 chain | 21:45 |
| larsc | _florent_: what are you running on the lm32? | 21:49 |
| _florent_ | for the moment , only the bios ;) | 21:51 |
| _florent_ | but I only wanted to know if some simple test code for the frame buffer existed for the bios | 21:51 |
| Fallenou | you can flash the PONG demo instead of the BIOS for instance | 21:54 |
| Fallenou | it makes simple use of the framebuffer | 21:54 |
| Fallenou | https://github.com/fallen/milkymist-pong | 21:55 |
| _florent_ | interesting! | 21:55 |
| Fallenou | this is working on the M1 board | 21:55 |
| _florent_ | that's what I need I think | 21:55 |
| Fallenou | you can play 1-player pong with the push buttons and VGA output | 21:55 |
| _florent_ | only a simple code that generate video | 21:56 |
| _florent_ | thanks | 21:56 |
| Fallenou | you're welcome :) | 21:56 |
| _florent_ | I have to go | 21:58 |
| _florent_ | I'll send you a capture of the pong demo in 1080p when it will be working ;) | 21:58 |
| _florent_ | bye | 21:59 |
| Fallenou | hehe very good :) | 21:59 |
| Fallenou | a video ;) | 21:59 |
| Fallenou | bye ! | 21:59 |
| lekernel | Fallenou, iirc the pong demo still uses the old SoC interface and should be loaded with netboot/flterm/flashboot (not flashed instead of the bios) | 22:32 |
| Fallenou | the pong demo for the ml401 maybe | 22:34 |
| Fallenou | but the pong demo for M1 is a replacement for the BIOS | 22:34 |
| Fallenou | it initializes ddr controler etc | 22:35 |
| Fallenou | it calls _sdram_init | 22:35 |
