Hi,
we found a problem in the pover supply chain.
We fixed this and now the board that was unstable seems to work properly.
Pushing on the frequency we probably made a hidden problem come to light.
So I think I can also confirm that the new settings to make the iMX27 working
@400MHz should be corr

It's a useful debug command!
Here it is its output:
barebox:/ dump_clocks
chip id: [2,882,1,01d]
mpll: 6 Hz
spll: 24000 Hz
arm: 4 Hz
perclk1: 2000 Hz

Silicon Rev. of my iMX27L is V2.1 (code M72J).

Hi Igor,
What revision of imx27 silicon do you have?
If it's a rev2.0 or 2.1, you shoult take a look a the freescale errata in
order to set your PLL properly.

Hi,
I'm working on a custom board based on iMX27L. Initially I worked with Redboot
as Linux bootloader but now, I'm happily working with Barebox (2012.01.0)
having replaced Redboot with it.
Everithing is fine (thanks to the guys in the list for helping me!) but...
I noticed that my Linux apps run
