Hi,

We are using P1022 processor based custom board.

SDKv1.9 is used to bring up Linux on this board.Using SD card interface we are able to run the U-boot.

While running kernel image(uImage) through uboot from SD card,We are getting console prints up to "Loading Device Tree to 004e5000, end 004ebc27 ... OK" and hangs.After enabling DEBUG macro in u-boot,prints are coming up to "## Transferring control to Linux (at address 20000000) ..." and hangs.

 

LOG:

## Booting kernel from Legacy Image at 01000000 ...

   Image Name:  

   Image Type:   PowerPC Linux Kernel Image (gzip compressed)

   Data Size:    4256593 Bytes = 4.1 MiB

   Load Address: 20000000

   Entry Point:  20000000

   Verifying Checksum ... OK

    Loading Device Tree to 004e5000, end 004ebc27 ... OK

## Transferring control to Linux (at address 20000000) ...

   hangs......

 

By running codewarrior in attach mode,we are getting PC value as 0xe00.

Can any one please help me in this issue.
