[U-Boot-Users] problems transferring control to linux (ppc)

[Alberto Sala]

Hi all,

we are porting u-boot/linux to a custom board based on mpc8280.
After having made u-boot-1.1.4 work, we tried booting some 
test-configured linux 2.6.15 kernels.

If we start u-boot using Trace32 (lauterbach) all goes well and linux 
gets loaded, but if we do the same steps disconnecting Trace32, u-boot 
seems to work properly, but as soon as the control is transferred to 
linux all seems to be hanged, and the last words visible on the serial are:

[...]
## Loading RAMDisk Image at 00400000 ...
   Image Name:   Test Ramdisk Image
   Image Type:   PowerPC Linux RAMDisk Image (gzip compressed)
   Data Size:    1374924 Bytes =  1.3 MB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
## initrd at 0x00400040 ... 0x0054FB0B (len=1374924=0x14FACC)
   Loading Ramdisk to 07e4e000, end 07f9dacc ... OK
## Transferring control to Linux (at address 00000000) ...

We are wondering if this is an issue involving u-boot or if this is 
related to linux config (in this case sorry for being off-topic).


Thanks for any help!!

Ciao,
Alberto
