I am testing the speed of sd/mmc in dm355 which using kernel 2.6.18. bash-3.00# mount /dev/mmcblk0p1 /mnt -o sync bash-3.00# time cp /tmp/ramdisk.img.gz /mnt/
real 0m19.996s user 0m0.000s sys 0m0.960s bash-3.00# ls -l /tmp/ramdisk.img.gz -rwxr--r-- 1 root root 3476678 Jan 1 00:01 /tmp/ramdisk.img.gz soļ¼the speed about mmc is about 170 kb/s,but i want speeds about sd/mmc above 1.5M/s,how can i optimize the driver ? 2009-08-03 zuowenping
