Hi, Yiming
1. when use sudo fdisk -l, the SD shows as below.

2. when doing sudo dd if=sdcard.img of=/dev/sdb

3. when take off SD card, connect it to windows OS, the card space decrease dramtically.

4. when put the card into the board, also copy below FW into the SD card.

5. Firstly, set SW 2 for default, power on the baord, press anykey during the u-boot to halt in, then in putty screen,doing below command:
=> fatls mmc 0:1
=> fatload mmc 0:1 a0000000 firmware_ls1028ardb_uboot_sdboot.img
=> mmc write a0000000 8 75000
=> setenv bootcmd 'qixis_reset sd'
=> saveenv
=> reset
after reset,
6. Then, power off, set SW 2, 3, 5 or only SW2 for below:
SW2=10011001; SW3=11110000;SW5=00111001
7. Power on again, putty show as below, seem not boot into OpenIL
