<P><FONT SIZE=2>Hi Yuantian<BR>
<BR>
Thanks for the tip, it's working fine on kernel 3.4.<BR>
<BR>
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"....<BR>
<BR>
Best regards,<BR>

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

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>
<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>

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>
