armhf kernel and library support for imx6

Hi all,

We are developing a IMX6DL board, and we have to run a detection algorithm over a camera image stream.

In order to improve the performance of execution, we are now trying to switch from the current armel build to a armhf build,

but we have not yet managed to achieve this.

We have found out this discussion armhf libraries for imx6 and we have not yet figured out if, nowadays, support for armhf

architecture exists or not for the imx6 platform...Can anyone help us to find out?

I thank you in advice for any help,

Best Regards

Daniele

I'm currently using a Debian Wheezy armhf, kernel 3.10.17 on a Udoo Dual Board, which is based on the imx.6DL. You can find some armhf Ubuntu or Debian rootfs on their website. They even have a Yocto to build your own rootfs, I guess you can adapt it to your board with a bit of tweaking.

So yes, it exists. I'm doing some image processing with openCV and some NEON code to speed up things a bit, and gained a little more than 30% in performance compared to a softfp test :smileyhappy: ! This is quite nice !
