| 12:04 | paulk-collins | jnettlet, hey, I see on the device tree for cubox-i and imx6 in general that things like hdmi audio and spdif depend on SDMA, which needs a non-free firmware |
| 12:04 | paulk-collins | is it avoidable? |
| 12:04 | paulk-collins | if not, it it easy to replace, considering there are sources for earlier imx version |
| 12:13 | paulk-collins | mhh doesn't really look much like source code |
| 12:19 | obinou | I did work on that a long time ago on imx31 |
| 12:20 | obinou | if it didn't changed , it's a tiny microcontrolled embedded |
| 12:20 | obinou | with a specific instruction set |
| 12:21 | obinou | to handle DMA stuff. There is some documentation in the imx6 manual itself I think |
| 12:21 | jnettlet | paulk-collins, that is a misconception. |
| 12:21 | obinou | there is no source per see |
| 12:21 | jnettlet | the SDMA engine works as is. It can take scripts to optimize certain DMA channels and the ones provided by Freescale are binary only |
| 12:22 | paulk-collins | right, so there is something already running there |
| 12:22 | paulk-collins | is it enough to have hdmi audio and other features that depend on it? |
| 12:22 | jnettlet | however there is already a developer that has hacked together some perl code that allows you to write your own optimization routines and build it into a compatible firmware file |
| 12:22 | paulk-collins | or are scripts needed |
| 12:22 | paulk-collins | jnettlet, I've seen that, indeed |
| 12:23 | paulk-collins | http://billauer.co.il/blog/2011/11/imx-sdma-assembler-example/ |
| 12:23 | jnettlet | the scripts help under heavy memory bandwidth pressure (think of it like QOS for dma) but generally no they aren't necessary |
| 12:24 | paulk-collins | alright |
| 12:24 | paulk-collins | I'll go without them and see |
| 20:20 | sam_nazarko | Are we getting nearer to that 3.14 rls yet? |
| 20:21 | sam_nazarko | I'm reluctant to look at OSMC on CuBox-i until thne. |
| 20:31 | jnettlet | sam_nazarko, yes. much closer. Initial non-developer testing is being done |
| 21:56 | Z0l | hello |
| 21:57 | Z0l | can somebody help me troubleshoot an hdmi problem between a cubox i4pro and a sony tv? the device cannot read out the edid and that taints the kernel, making the hdmi audio out unusable |
