customizing nto for 855t  
Hi,

I am trying to customize 855t for a custom board. I downloaded the 800fads bsp and made changes to adjust clock speed 
and some code in init_intrinfo().

As the first step i just want kprintf to work. Its working while startup but hangs after attempting to start the kernel.
 Here is the output just before it hangs (I put a print_callout() before print_syspage() )...

program load complete, entry point: 0x80014a9c, size: 0x15184cú
  reboot:0000c710 power:00000000
  timer_load:0000c760 reload:0000c778 value:0000c7a4
  0) display:0000c7bc poll:0000c82c break:0000c8a4
  1) display:00000000 poll:00000000 break:00000000

System page at phys:0000c000 user:0000c000 kern:0000c000
Starting next program at v80051a08


thts it... it just hangs! For debugging I my first line in main() in proc/main.c is
kprintf("Hello world\n"). Why doesnt it print this?????

ok got it...
gave different address base in init_raminfo and imagebase in buildfile though the rommon up sets both to access same 
memory (i.e. 0x80000000 and 0x00000000 both access phy addr. 0)...
taking base as 0x0 in both worked :)... now got to find out y devc-serppc800 is not starting...
