Hi!
I'm trying to get root-filesystem over NFS running. I'm a bit confused about all the new stuff and I don't know where I shall start searching for the problem :-(
I have: Board: Artila M501 board with AT91RM9200 U-Boot: 1.1.2 Linux: 2.6 Flash: 16MB SDRAM: 64MB
My U-Boot configuration is:
*** START *** baudrate=115200 ethaddr=00:13:48:00:77:b5 rootpath=/opt/arm lel=1 initrd=0x20800000,8192000 ramdisk_size=15360 root=/dev/ram0 rw loader=tftp 21000000 m501_64M.alf mtdparts=phys_mapped_flash:128k(loader)ro,128k(reserved)ro,1408k(linux)ro,2560(ramdisk)ro,-(userdisk) filesize=3A3 netmask=255.255.255.0 bootcmd=bootm 10040000 101a0000 kernel=tftp 21000000 M501K;erase 10040000 1019ffff;cp.b 21000000 10040000 $(filesize) skernel=loadb 21000000;erase 10040000 1019ffff;cp.b 21000000 10040000 $(filesize) ramdisk=tftp 21000000 M501R;erase 101a0000 1041ffff;cp.b 21000000 101a0000 $(filesize) sramdisk=loadb 21000000;erase 101a0000 1041ffff;cp.b 21000000 101a0000 $(filesize) ipaddr=192.168.2.196 bootdelay=1 bargs=setenv bootargs mem=64M console=$(console),115200 initrd=0x20800000,8192000 ramdisk_size=15360 root=/dev/ram0 rw mtdparts=phys_mapped_flash:128k(loader)ro,128k(env)ro,1408k(linux)ro,2560k(ramdisk)ro,-(userdisk) serverip=192.168.2.40 console=ttyS0 gateway=192.168.2.1 bootargs=root=/dev/nfs rw nfsroot=192.168.2.40:/opt/arm ip=192.168.2.196:192.168.2.40:192.168.2.254:255.255.255.0:michael-laptop::off console=ttyS0,115200 bootm=10040000 - 101a0000 stdin=serial stdout=serial stderr=serial *** END ***
If I start my Board, the kernel boots and it looks fine until I get a kernel panic --> See the attached textfile!
Do you have any hints what the problems might be. I'm pretty sure that the NFS-Server works fine, but I'm not sure 100% (How can I find out if it works? Any Idea?).
Thanks! Michael
