Could you help me?
at MPC850 i let USB host work,but have some problems.the host driver is m8xxhci.c of brad.
i usb the command :mknod sda b 8 0, mknod sda1 b 8 1,in the direction of dev.is it ok?
when i mount OnlyDisk of Netac (mount /dev/sda1 /mnt/usbdisk),the infomation displayed as below:
VFS: Can't find an ext2 filesystem on dev sd(8,1).
when i cd /mnt/usbdisk,and vi my.txt,i also face some problems.the problems as below:
if i use backspace key,the console will display ^H;when i usb up,down,left and right key,the screen will roll.the infomation of -- caught signal 14 (alarm) -- exists at the bottom.
in the end i send my boot infomation to you.thank you in advance! Best regards! shuiming lin
