I wrote the pMulti image into flash 2a00000
ppcboot is at location 2800000
i did the following settings
setenv bootcmd bootm 0x2a00000
and also  did saveenv ...
once i reset the board it just hangs thats it...
even ppcboot promp does not come ..
i have to burn ppcboot again and again in that case ..
i want the kernel to boot up upon power ..
but here even the existing ppcboot doesnt work ..

this is the fliinfo
