| 06:13 | kremlin | hey! -- can someone help me with the imx6q's hdmi framebuffer? |
| 06:46 | jnettlet | kremlin, what do you need? |
| 06:46 | jnettlet | topi`, yeah. They got a bit over the top in the ads department for my liking. |
| 06:47 | kremlin | jnettlet: well, for one, i am having trouble ascertaining the datapath from framebuffer bits -> HDMI transmitter |
| 06:47 | kremlin | i have a DMA'd pixel framebuffer, i am just not sure where to put its address |
| 06:49 | jnettlet | kremlin, what image format is the pixel framebuffer in? |
| 06:49 | kremlin | jnettlet: i can set it to anything, but currently 24bit color RGB |
| 06:51 | jnettlet | kremlin, okay do you need accelerated blitting, or just dumping the pixels manually? |
| 06:51 | kremlin | jnettlet: dumping manually |
| 06:53 | jnettlet | for hdmi /dev/fb0 is the default device then |
| 06:53 | kremlin | jnettlet: i am writing a device driver for bsd, not linux |
| 06:54 | jnettlet | then you need to write drivers for both the IPU, and the HDMI transmitter |
| 06:55 | kremlin | that's what i'm doing, but i am confused as to how my pixel framebuffer in memory fits in with the IPU |
| 06:59 | jnettlet | you need to take the parameters for your framebuffer, pixel_fmt in and out, size etc and then program an ipu channel to read from it. |
| 07:00 | kremlin | jnettlet: gotcha, thanks for your help |
| 07:00 | jnettlet | and there are restrictions regarding strides and sizes that if they aren't adhered to can cause the IPU to lockup |
| 07:01 | kremlin | i'll watch out for those |
| 07:02 | jnettlet | okay good luck |
| 23:15 | KodiakFi-at-home | Anyone able to confirm the barrel connector for the Cubox i4-pro is 4mm? |
| 23:15 | KodiakFi-at-home | That's my ruler measurement - I don't have a micrometer handy |
| 23:18 | KodiakFi-at-home | I mean it could be a 5.5m |
| 23:18 | kremlin | KodiakFi-at-home: let me check |
| 23:19 | KodiakFi-at-home | Thans kremlin - the more I look at it the more I'm thinking 5.5mm |
| 23:19 | KodiakFi-at-home | damn my inability to keep track of my tools |
| 23:20 | KodiakFi-at-home | brb kremlin |
| 23:21 | KodiakFi-at-home | thx in advance of course in case I'm not at keyboard when you respond |
| 23:21 | kremlin | KodiakFi-at-home: 5.5mm. my adapter's datasheet confirms |
| 23:21 | kremlin | pin is line, barrel is gnd |
| 23:23 | KodiakFi-at-home | ah thanks a bunch Kremlin - I couldn't find the specs. I'm cutting everything over to 2.4A USB to clean up cables |
| 23:27 | kremlin | :) |
