We are working on it.

Other then create a yocto layer. WE are working to add the supprto for plyflex imx6 on the 3.10.17.

the step to do are: writing the dts file and add some driver non currently present in the kernel revision (audio chip tlv320aic 3007 and regulator chip da9063).

still work in progress. ANy contribution and help will be appreciated.

There is dtsi file for mx6 phytec phyflex board on recent kernel:

https://git.kernel.org/cgit/linux/kernel/git/shawnguo/linux.git/tree/arch/arm/boot/dts/imx6qdl-phyte...

In this version there is audio and regulator support available.

well not easy to do... the kernel version differ quite a bit.. so a lot of undefine etc etc to solve...

[Selea]

Phytec on its forum said that they will release the kernel 3.10.17 (based on freescale one) next friday.

I still working on it because i still have some errors in regulator.

Hi,

now i worked to use Yocto with phyflexIMX6q. We are able to compile kernel 3.10.17 (I made dts file) and distro, and it is working with phyflex imx6Q on a own made carrier board.

what is missing:

1) USB host and OTG (used directly from internal PHY as on sabdreSD without any external HUB chip), is not working due to something not correctly configurated on enable of power supply (the enable is always off), I'm sure that it is not hardware issue beause if I use the 3.0,35 kernel from phytec the USB is working fine on the same hardware.

2) I'm trying to use sensor on mipi interface (ov5640 mipi) and it is working, but when I try to use a sensor on the 2nd parallel interface (CSI1 that should go to ipu2) , it find the sensor it regiter the V4L2 dev but when i try to read from that dev (/dev/video2) it always says read timeout error...so something is missing in configuration of IPU/CSI ????

I attach here the DTS files I made .. thanks for any help.

Try checking the regulators node. In the dtsi files from mainline they are active low:

https://git.kernel.org/cgit/linux/kernel/git/shawnguo/linux.git/tree/arch/arm/boot/dts/imx6qdl-phyte...

On yours they are active high. I don't have the schematics to tell what is the correct.

I would suggest you to do the same as in the mainline version.

If it still does not work, I would suggest contacting Phytec.

[Selea]

I fixed USB H1 was the configuration of IOMUX GPIO_0 in DTS file...

now i go on with USB OTG....

then parallel sensor on CSI1 IPU2

then audio and regulator...

i can do it!

;-)

on the schematics of the phyflex the GPIO go to a gate of a mos so they have to be high to activate the mos , the mos drain goes then low activating the VPUpower... so active high should be right. the problem is that the gpio doesn't go high....

[Selea]

dts files I made

[Selea]

that verions is anyway corerctly "patched" as the kernel ported by freescale (i mean the official 3.10.17_ga)?

Omar

[Selea]

I can answer "no" to my previous question, so I could use it as reference to port the missing driver in the 3.10.17_ga kernel from freescale...

right?

[Selea]

thanks, i will look at it!!!!

I would be interested in yocto support for the Phytec phyFLEX imx6 as well. A special layer for Phytec boards would be nice. Is there any progress on this subject?
