[Buildroot] Compile Linux with Buildroot for i.MX28 EVK

[Mikael Åsberg]

Hey,

Ok great, thx!

One last thing, depending on which bootloader that is used, i.e., u-boot, barebox etc., does it matter which kernel image that is used for the boot (zImage, uImage, vmlinux)?
If I use barebox, which image can I use? (I prefer an uncompressed kernel)

Kind regards

You original question was about the Linux kernel not Barebox.

Barebox includes support for the TX28 board which is based on i.MX28
(tx28stk5_defconfig).

The kernel (and Barebox) defconfig files should include all the relevant
settings, including this one.
