Hi Yaroslav, I would make this two different devices. One for SD-card flash and one SPI flash device. Then you would not support sysupgrade between SD-card and SPI. The initial flashing of the SPI image can be done by just dd the image to the SPI flash from the SD card image. I would build the SPI flash image in a similar way for any of the MIPS deices with SPI NOR flash. I tried to make the SPI work in OpenWrt on this device some time ago, but never finished: https://git.openwrt.org/?p=openwrt/staging/hauke.git;a=shortlog;h=refs/heads/sunxi-spi Hauke
