Cannot boot an kernel version other than 2.6.35 on P2020RDB-PCA

Thanks for the tip, it's working fine on kernel 3.4.
And yes the board works on linux kernel 2.6.35. I have downloaded the mainline code on kernel.org and use the "qoriq_sdk_defconfig" provided with system builder of Freescale, but it is only working with this defconfig file and not with the default one "mpc85xx_defconfig"....

Hi Cedric MAUSSIRE,
P2020RDB-PCA Board gets supported since kernel 3.3 in mainline code.
Are you sure the board works on kernel 2.6.35?

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 :
## Booting kernel from Legacy Image at 01000000 ...

I have unsuccessfully tried to rebuild the device tree blob and use the default kernel configuration "mpc85xx_defconfig" that comes with the mainline code.
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.
