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

Thu Mar 22 14:44:40 EST 2007

Hi everyone,

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

Trying get a working kernel: boot from flash and use ramdisk from flash with 
the following configuration:
TQM 860L, 64MB RAM (not 16MB as the standard module)
ELDK4.1
Kernel 2.6.19 from ELDK
u-boot 1.1.6

u-boot environment:
=> printenv
bootcmd=run flash_self
bootdelay=5

mount root filesystem over NFS;echo

nfsargs=setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:${rootpath}
addip=setenv bootargs ${bootargs} ip=${ipaddr}:${serverip}:${gatewayip}:
${netmask}:${hostname}:${netdev}:off panic=1
flash_nfs=run nfsargs addip;bootm ${kernel_addr}
flash_self=run ramargs addip;bootm ${kernel_addr} ${ramdisk_addr}
net_nfs=tftp 200000 ${bootfile};run nfsargs addip;bootm
