开发板可以正常nfs启动,但是做实验nfs下载uImage_nolcd时出现错误,如下所示,请大神指点一下问题在哪?
OpenJTAG> nfs 30000000 10.0.40.199:/work/nfs_root/fs_mini_mdev/uImage_nolcd dm9000 i/o: 0x20000000, id: 0x90000a46 DM9000: running in 16 bit mode MAC: 08:00:3e:26:0a:5b could not establish link File transfer via NFS from server 10.0.40.199; our IP address is 10.0.40.200 Filename '/work/nfs_root/fs_mini_mdev/uImage_nolcd'.

我从网盘里找到一个U-Boot 2012.04.01 版本的,请问这个是最终版本么?因为我用的时候和以前的不太一样,按空格键不出现菜单了,只有如下所示的界面:
U-Boot 2012.04.01 (Dec 18 2012 - 04:44:13) CPUID: 32440001 FCLK: 400 MHz HCLK: 100 MHz PCLK: 50 MHz DRAM: 64 MiB WARNING: Caches not enabled Flash: 0 KB NAND: 256 MiB In: serial Out: serial Err: serial Net: dm9000 Hit any key to stop autoboot: 0 SMDK2410 # |

用了这个版本的U-Boot去nfs下载还是不行,一样有下面的问题:

ERROR: Cannot mount
这问题可能来自两方面: 1.UBOOT 2.服务器 我们先确定服务器没问题,你在服务器上MOUNT 自己试试,比如执行这样的命令(这只是个例子,IP、目录需要自己修改): sudo mount -t nfs -o nolock,vers=2 10.0.40.199:/work/nfs_root/fs_mini_mdev /mnt 如果成功,就表示服务器没问题。 对于UBOOT问题,换上我们的u-boot-1.1.6 试试 |
