715

问答对人有帮助，内容完整，我也想知道答案 0 請問各位先進們: 最近拿到dm8148 evm，跟著USER GUIDE上的設定要用NFS 把ubuntu端的資料掛載起來，但遇到一直無法掛載的問題，請問要怎麼解，我有試過在VM ubuntu 10.04下自已當nfs client掛載是可以成功的，但是dm8148evm上tftp可以下載uimage成功 NFS 就是掛不起來，以下是log，尋找高手求救，謝謝 ti8148_EVM#setenv serverip 192.168.1.112 setenv bootcmd 'dhcp;tftp 81000000 uImage_DM814X_TI_EVM;bootm' TI8148_EVM#setenv autoload no TI8148_EVM#setenv nfsserver 192.168.1.112 TI8148_EVM#setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs rootdelay=5 rw nfsroot=192.168.1.112:/home/neil/dvrrdk/DVRRDK_04.01.00.02/target/rfs_814x,nolock nfsrootdebug mem=128M notifyk.vpssm3_sva=0xBFD00000 earlyprintk ddr_mem=512M vram=20M' TI8148_EVM#setenv serverip 192.168.1.112 TI8148_EVM#boot link up on port 0, speed 100, full duplex BOOTP broadcast 1 BOOTP broadcast 2 DHCP client bound to address 192.168.1.111 link up on port 0, speed 100, full duplex Using cpsw device TFTP from server 192.168.1.112; our IP address is 192.168.1.111 Filename 'uImage_DM814X_TI_EVM'.
