<P><FONT SIZE=2>Hello all,<BR>
<BR>
I am currently working on the Freescale P2020RDB-PCA Board, which has been delivred with the linux-2.6.35 kernel. I succeed in re-generating my own uImage in 2.6.35 thanks to ELDK, but when I want to move on to a newer or older version of linux, the system does not respond any longer just after the boot whith the nfsboot command, the logs are :<BR>

## Booting kernel from Legacy Image at 01000000 ...<BR>
Image Name: Linux-2.6.39<BR>
Created: 2012-05-29 8:24:54 UTC<BR>
Image Type: PowerPC Linux Kernel Image (gzip compressed)<BR>
Data Size: 3514882 Bytes = 3.4 MiB<BR>
Load Address: 00000000<BR>
Entry Point: 00000000<BR>
Verifying Checksum ... OK<BR>
## Flattened Device Tree blob at 00c00000<BR>
Booting using the fdt blob at 0xc00000<BR>
Uncompressing Kernel Image ... OK<BR>
Loading Device Tree to 00ffa000, end 00fffd4a ... OK<BR>

NB : nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=192.168.1.1:$rootpath ip=192.168.1.2:192.168.1.1:192.168.1.1:255.255.255.0:P2020RDB-PC:eth0:off console=ttyS0,115200<BR>
<BR>
I have unsuccessfully tried to rebuild the device tree blob and use the default kernel configuration "mpc85xx_defconfig" that comes with the mainline code.<BR>
<BR>
My systems seems to be linux-2.6.35 dependent, I do not known how it can be possible, because I can use the kernel.org source of the 2.6.35 whith no problems but when I use the 3.0, for example, with the same configuration but it does not work.<BR>
