Command "dd" is used for writing .img file to SD card.

See below:

sudo dd if= sdcard.img of=/dev/sdb seek=8 bs=512

The LS1012a supports QSPI as the boot source. Use u-boot commands for upgrading firmware QSPI NOR.

Use "mmc" command of u-boot to write sdcard.img to SD card or use "dd" command on your host Linux PC for write this image to SD card.

For firmware.bin to QSPI NOR, how can I update mtd0 under OpenWrt Linux?

For sdcard.img to SD card, how to update mmcblk0 under OpenWrt Linux? use dd with /tmp?
