Hi,
I'm using a FSForth NS9750 developer's kit and I got into some problems booting from NFS. My server ip stated in u-boot is 167.116.150.102 but when linux is looking up RPC 100003/2 and 100005/1, it's trying ip address 167.116.183.37. Failing to find it, it goes into kernel panic.
Any idea why the server's ip address is changed?? I tried another kit to boot from 167.116.150.102 and it worked fine but there are no differences in the u-boot environment parameters.
Any hints??
Thanks, Terence Soh.
My u-boot environment is
