Hello all,
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.
Best regards,
Cedric MAUSSIRE
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?

Hi Yuantian
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"....
Best regards,
Cedric
