ltp-ddt nor qspi spi调试中需要修改的地方

blk_device_dd_readwrite_test.sh

before

SRC_FILE="/home/root/srctest_file_${DEVICE_TYPE}_$$"
do_cmd "time dd if=/dev/urandom of=$SRC_FILE bs=$DD_BUFSIZE count=$DD_CNT"

after

SRC_FILE="/home/root/srctest_file_${DEVICE_TYPE}_$$"

do_cmd "mkdir -p `dirname $SRC_FILE`"

do_cmd "time dd if=/dev/urandom of=$SRC_FILE bs=$DD_BUFSIZE count=$DD_CNT"
由于系统中没有/home/root文件夹，直接dd会出错，先要建立文件夹。

由于所有模块都是build-in不需要modprobe

blk_device_prepare_format.sh

before

if [[ "$DEV_NODE" =~ "mtd" ]]; then
do_cmd printout_mtdinfo "$DEV_NODE"
do_cmd modprobe mtdblock
do_cmd modprobe ubi
do_cmd modprobe ubifs
fi

after

if [[ "$DEV_NODE" =~ "mtd" ]]; then
do_cmd printout_mtdinfo "$DEV_NODE"
#do_cmd modprobe mtdblock
#do_cmd modprobe ubi
#do_cmd modprobe ubifs
fi

blk_device_dd_readwrite_test.sh -f "jffs2" -b "1M" -c "32" -d "nor"

由于硬件问题32不行，改为10，可以跑通。

->->blk_device_filesystem_perf_test.sh

before

do_cmd blk_device_umount.sh -m "$MNT_POINT"
   do_cmd "echo 3 > /proc/sys/vm/drop_caches"

   #do_cmd "mount -t $FS_TYPE -o $MNT_MODE $DEV_NODE $MNT_POINT"

after

#do_cmd blk_device_umount.sh -m "$MNT_POINT"
   do_cmd "echo 3 > /proc/sys/vm/drop_caches"

   #do_cmd "mount -t $FS_TYPE -o $MNT_MODE $DEV_NODE $MNT_POINT"

   do_cmd "echo 3 > /proc/sys/vm/drop_caches"

filesystem_tests -read之前umount mount会报错，暂时#掉。
