Problem with flash-kernel script on PandaBoard with Ubuntu image and Linaro kernel

[David Cullen]

Hello, ubuntu-devel-discuss,

I have a PandaBoard system created from the image at

>    http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-preinstalled-desktop-armhf+omap4.img.gz

I added the Linaro kernel repository and installed the Linaro kernel
because I had problems with the Linaro Ubuntu image.

However, when I ran the "flash-kernel" script, I got the following
error message:


> Kernel /boot/vmlinuz-3.4.0-1-linaro-lt-omap does not match your subarchitecture
> omap4, therefore not writing it to flash.

I worked around the problem by making a minor change to the
"flash-kernel" script.

I compared the "flash-kernel" script in the Linaro-Ubuntu image to
the Ubuntu image and derived the following patch:

My questions are

  1. Is it appropriate to suggest a patch to the Ubuntu
"flash-kernel" to support the use of Linaro kernels?
  2. If so, where should I submit the patch?
