Is there any dev working on the NanoPi R2S

As I said earlier, when compiling arm-trusted-firmware, the BL31 file was not created. The reason was that I had the BL31 variable set to my wrong (from Internet) bl31.elf file.
When I removed this variable, (unset BL31) then the arm-trusted-firmware/build/rk3328/release/bl31/bl31.elf file was created and after setting the BL31 variable (export BL31=.....) and compiling the uboot, everything started working wonderfully.
I have one question for you. Do you have any idea how to run OpenWrt from SPI Flash (I have a W25Q128 soldered in) ?

Did anyone have a working guide to expand space for packages on sd with squashfs image ?
