<div><br>Hi all: <br> My board is a custom MPC8260 board, with 4MB flash,128MB SDRAM.<br>I modified pq2fads.dts and pq2fads_defconfig,they are in the mail's accessory,<br>then compile the kernel.The kernel halt after displaying "Booting using OF flat tree.".<br>[u-boot]: bootm 1000000 2000000 3000000 <br>## Current stack ends at 0x07f9bd58 <br>* kernel: cmdline image address = 0x01000000 <br>## Booting kernel from Legacy Image at 01000000 ... <br> Image Name: Linux-2.6.30 <br> Image Type: PowerPC Linux Kernel Image (gzip compressed) <br> Data Size: 1510119 Bytes = 1.4 MB <br> Load Address: 00000000 <br> Entry Point: 00000000 <br> Verifying Checksum ...

<br>Is the error in my u-boot, device tree blob or linux kernel side?
<br>what i should look at?
