Hi<BR>
We are using AMCC PPC 405EP Taihu board, our aim is to run the C code on kit. The kit already contains U-boot, linux kernel, and Ramdik images on Flash memory. We are successfully configured C-Kermit, NFS server(/opt/eldk4/ppc_4xx, /mnt/nfs-share) on host(Fedora Core 4). We are succeeded loading the files from NFS server after U-boot, but we are failed to mount the files (/mnt/nfs-share) on target after kernel booting on kit. But booth host and target are communicating after kernel booting (using ping). <BR>
<BR>
We using the command to mount /mnt/nfs-share on target(Busy box 1.1.0):<BR>
<BR>
target # mkdir /mnt/nfs<BR>
target # mount –t nfs 192.168.1.18:/mnt/nfs-share /mnt/nfs<BR>
error: monting 192.168.1.18:/mnt/nfs-share on /mnt/nfs : No such directory or file<BR>
<BR>
Can u tell how to mount flash file system on target, using that one also we can run (bebug) the programs on kit using gdb<BR>
<BR>
So we are failed to transfer any file on to the target. Is it any way to run the program on kit using host side ppc_4xx-gdb tool and target side gdbserver tool?<BR>
<BR>
Is there any another way to run the code on the target or <BR>
<BR>
Below is the problem we are facing while passing arguments to the kernel …….<BR>
we are expecting that there is no nfs device notice on the target, we tried different ways but we have failed to mount the root file system on linux or to mount host files on target, But we are succeeded loading the files from NFS server after U-boot<BR>
