[Freescale P2020DS] Porting linux kernel 2.6.27
Hello,
I'd like to install a linux kernel 2.6.27 on my P2020DS board. Actually, the baseline kernel version is 2.6.28.1. So i have downloaded on kernel.org my kernel, I have copied the p2020ds_def_config (provided with the board and kernel 2.6.28.1) and renamed it to .config in the folder of 2.6.27 kernel Then, make CROSS_COMPILE=powerpc-none-linux-gnuspe- ARCH=powerpc uImage ... I copied uImage in the /boot directory Reboot. . . . Uboot prompt : #setenv bootargs root=/dev/sda3 rw console=tty0 #ext2load scsi 0:3 0x1000000 /boot/uImage xxxxx bytes read #ext2load scsi 0:3 0xc00000 /boot/ramdisk xxxxx bytes read bootm 0x1000000 0xc00000 WARNING: adjusting available memory to 30000000 ## Booting kernel from Legacy Image at 01000000 ...
