1. I have complie sdcard.img following document below successfully. (environment:ubuntu 18.04 LTS running as virtual machine in my windows pc)
2. the sdcard.img burn into the sd card successfully
3. copy below file to sd card
4. Insert the SD card into the LS1028ARDB, the DIP switch (SW2) set as manual shows.
5. Link the board with Tera Term
the screen shows nothing.
Hello yu bai,
The image sdcard.img contains entire image can be programmed into the SD, includes RCW, DTB, U-Boot, kernel, rootfs, and necessary applications.
$ sudo dd if=./sdcard.img of=/dev/sdx
/dev/sdx is the SD card device name in your host machine.
So, no need step 3 at all.
Thanks,
Yiping
Hi, Yiming
Do I need mount my sd card with sdcard.img to the target board(ls1028ardb)?
In the boot mode (show in tera term), i just input "df -h“ command, the result shows the sd card(mmcblk0) is not mounted?
Is that the root cause?
Thanks a lot.

In the following command, /dev/sdx should be the device name not partition name.
$ sudo dd if=./sdcard.img of=/dev/sdx
/dev/sdx is the SD card device name in your host machine.
You should use the following command.
sudo dd if=/.sdcard.img of=/dev/sdb
hi,Yiming
Thanks.
I already flash the sdcard.img(for openIL) to the SD card using my PC.
My question is, do i need also mount(挂载)the SD card to the LS1028ARDB board. Currently, when I insert the SD card to the board slot, then set SW2 as 1001001, then power on, the tera term(serial communication tool) shows nothing. the serial port also set as manual said.
How to solve this? I used the SD card shipped with the board.
You need to run the following command to deploy images to SD card, please use /dev/sdb which is the device name not partition name.
sudo dd if=./sdcard.img of=/dev/sdb

Hi, Yiming
Thanks for your reply.
But, when delete step 3, the board also can't work.
1. Before burn sdcard.img to the SD card, the card is formated.
2. For the DIP switch setting, i just need follow the document,yes? just set SW2, other SW will not be changed?
3. for which version and makefile is recommend from your side? OpenIL1.7 or 1.8? 64b or ubuntu or emmc?
4. I just need set SW2, insert the SD card, and open tera term, then power on the board? it seems the screen still show nothing on tera term.
Thanks a lot.
