Hello,
I'm trying to startup the latest kernel image (2.6.31) for my mpc8572ds machine. I have downloaded the kernel's source code at kernel.org and i have compiled it with a native ppc compiler using make uImage.
At this moment I have in my system my uImage and u-boot-2009-08 programmed in the flash memory. The bootargs are "root=/dev/sda6 rw console=ttyS0,115200" and the dtb file was generated by the script dtc included in the same kernel source code.
I have done:
../pathtoscript/dtc -I dts -O dtb -o mpc8572ds.dtb pathtodts/mpc8572ds.dts
An finally I have executed the following instruction with the following result:
=> ext2load scsi 0:6 0x01000000 /boot/uImage Loading file "/boot/uImage" from scsi device 0:6 (sda6) 1582778 bytes read => ext2load scsi 0:6 0x00c00000 /boot/mpc8572ds.dtb Loading file "/boot/mpc8572ds.dtb" from scsi device 0:6 (sda6) 13748 bytes read => bootm 1000000 - c00000 WARNING: adjusting available memory to 30000000 ## Booting kernel from Legacy Image at 01000000 ... Image Name: Linux-2.6.31 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1582714 Bytes = 1.5 MB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK ## Flattened Device Tree blob at 00c00000 Booting using the fdt blob at 0xc00000 Uncompressing Kernel Image ... OK
The startup stuck here and I don't know why, I have tried to startup my kernel with old dtb's files but i have get some "kernel panic" errors and some "bad structure of the file (/choosen)".
Thanks.
