SECOA62 lvds7 screen not working

[modjo756]

Hi, i have rebuilt a complete image (from scratch) for secoA62 Krogoth branch. All work fine but lvds7 is not working, see this post for details : http://www.udoo.org/forum/threads/openembedded-yocto-on-udoo-boards.2965/page-18#post-21027

I have make a patch to use the lvds7 on secoA62, see here : patchLvds7

To have a working screen, i removed the second channel of the lvds (i don't know the reason of this bug ...)

In this patch, i also activate some devices :

• spi2
• can1
• i2c1
• uart5

All seems to be working fine (i tested all of this). The point that need to be improved is audio. If i uncomment ssi1 on the patch (line 337) i have some errors during the build of the kernel ... Another point is the power button, not working ... Graugans, i don't know if you plan to use a new version of kernel (4.1 ?) but it could be a base ! Another point, to enable spidev you need to add CONFIG_SPI_SPIDEV=y in defconfig. My work is based on seco kernel and Ekironji kernel

Audio is on my todo as-well I am unsure in what shape 4.1 for A62 is. A first step should be to bring device tree of A62 to the same level of udoo quad/dual. Then porting is more easy

@modjo756 could you please be so kind and add a Pull request for the CONFIG_SPI_SPIDEV=y in defconfig?

Kernel 4.1 is definitely on the list. I would like to play with device-tree overlays. I am not sure of there is support in the 4.1 NXP kernel or not.

[modjo756]

Yes i will do it this week end. Do i add my patch in the same time ?

[graugans]

For the patch I would like to go like I did in UDOO Neo. Or rework the whole selection of configuration. Like device-tree overloads

[modjo756]

ok no problem i understand. I let my patch in my git.
