Hi,<br>
<br>
Revisiting the issue below, it there a convinient way<br>
to use the FB in barebox without creating a flicker on the LCD in
the transition <br>
from Barebox to the kernel?<br>
<br>
Thanks,<br>
<br>

Do you know of some way to fix this (a patch for the freescale kernel
maybe)?

A simple way to check whether this is the problems is to just disable the
framebuffer in the kernel build, and make sure that you can boot again.
Then, the fix for this problem is to move the request_irq() call to the end of
the .probe routine.
You should not expect any kind of support from Freescale for their released
Linux kernels.

<pre wrap="">Hi,
When using the iMX35 freescale 3stack we are having some issues with the FB
driver. On device boot we enable the fb using "fb0.enable=1" and then try
to boot the kernel from nand. The problem is that after the kernel is
loaded to RAM and extracted the board hangs. If we do not init the fb0
device but simply boot the kernel it works fine. Trying "fb0.enable=0"
before booting also did not help.
Did anyone encounter this issue yet or are we doing something wrong?

<pre wrap="">
Are you using the freescale kernel? It doesn't handle loading the IPU driver
if the IPU has been enabled previously.. (an IRQ fires before all the driver
structures have been initialized and crashes)
Cheers,
Marc
