Tried out the following u-boot "setting":
setenv ramargs setenv bootargs ramdisk_size=3D6144 root=3D/dev/ram console=
=3DttyCPM0=20
rw

No change; still no output in the console

Note that my module has 64MB, rather that 16; I thought it doesn't matter, =
or?

Thanks again for your help
Tom

Thanks Wolfgang for your reply,

You're right, I can not really tell, whether it's frozen since I don't
have a BDM...
I'll try the console command you suggested, which I haven't had to use
before (U-boot 1.1.2 and older, Kernel 2.4, older ELDK)

Thanks

need from the experts on the list again.
The CPU freezes after the ramdisk gets loaded!

Does it really  freeze?  I  mean,  did  you  verify  this  witha  BDM
debugger,  or  do you just see no further output on the console? Note
that these are two fundamentally different things...

I don't see you passing any console=3DttyCPM0 argument here?
