Then, you'll need to first load an SPL to initialise the RAM: -sunxi-fel spl spl/sunxi-spl.bin +$ sunxi-fel spl spl/sunxi-spl.bin
Load the binaries we'll flash into RAM: -sunxi-fel write 0x4a000000 u-boot-dtb.bin -sunxi-fel write 0x43000000 spl/sunxi-spl-with-ecc.bin +$ sunxi-fel write 0x4a000000 u-boot-dtb.bin +$ sunxi-fel write 0x43000000 spl/sunxi-spl-with-ecc.bin
And execute U-Boot -sunxi-fel exe 0x4a000000 +$ sunxi-fel exe 0x4a000000
On your board, you'll now have all the needed binaries into RAM, so you only need to erase the NAND...
-nand erase.chip +$ nand erase.chip
Then write the SPL and its backup:
-nand write.raw.noverify 0x43000000 0 40 -nand write.raw.noverify 0x43000000 0x400000 40 +$ nand write.raw.noverify 0x43000000 0 40 +$ nand write.raw.noverify 0x43000000 0x400000 40
