Which linux kernel version

thomasgraf — Thu, 27 Jun 2013 09:45:12 GMT

We received our MX6Q-SabreSD development board from freescale.

Our future target is to create our own board using the i.MX6Solo and use PCIe to interface with wireless network cards.

Currently I try to use the linux-imx kernel. (Branch imx_3.0.35_4.0.0).

Unfortunately there is not PCIe support in the mainline 3.10-Kernel version.

For u-boot we are successfully using the current master branch from git://git.denx.de/u-boot.

What is the best way to be able to support current wireless lan PCIe cards? Hopefully I'll get the "old" patched 3.0.35-Kernel to boot soon.

the pci-e is working fine with branch imx_3.0.35_4.0.0, you need to enable it in ltib and recompile the kernel. i have tested it with wifi link 5100(intel chipset) and rootfs ubuntu 11.10, and wifi works fine.

4.0 release can be used to support PCIe interface. Re-compile of the kernel is required.

SW configurations:

Recompile of the kernel source codes is mandatory required.

# Run “make menuconfig” after run “make ARCH=arm imx6_defconfig”

Make sure that

# MX6 Options:

CONFIG_IMX_PCIE=y

Kernel configuration:

Tank you for the description. I think the main thing was to use the arm cross compiler from the freescale package and not the newer from ubuntu.
