Hi! I have: Board: Artila M501 board with AT91RM9200 U-Boot: 1.1.2 Kernel: 2.6.14-M5 (I know that U-Boot and Kernel are quite old, but I think for my learning purposes it is OK... Will try to update later.)
My problem: I'm trying to run root-fs over nfs... I know that my nfs-server is OK, because I can mount from another linux-pc. But I'm not able to mount nfs from my target-system. And I can't see any package from my target on wireshark which is running on the nfs-server -> So it seems that my target doesn't send any packet to the server or it get lost on my net.... Can you see any problem with my configuration? See configuration and bootlog below: Configuration: *************************** 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 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 gateway=192.168.2.1 console=ttyS0 bootargs=mem=64M root=/dev/nfs rw nfsroot=192.168.2.40:/opt/arm ip=192.168.2.196:192.168.2.40:192.168.2.1:255.255.255.0:kleiner_michi::off console=ttyS0,115200 bootcmd=bootm 10040000 stdin=serial stdout=serial stderr=serial *************************** log: *************************** Starting M501.............
