TQM 860L, 64MB RAM, ELDK4.1, TQM860L, Kernel 2.6.19

Tried out the following u-boot "setting":
setenv ramargs setenv bootargs ramdisk_size=6144 root=/dev/ram console=ttyCPM0 
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
