[BPI-R2 Pro] Update Miniloader/SPL or use it on SD card

tstusr · October 27, 2022, 5:20pm

Hello. Is there way to update Miniloader/SPL on EMMC? I am always getting this error when trying to flash it via upgrade_tool:

sudo upgrade_tool ul rk356x_spl_nand_v1.07.bin
Not found config.ini
Program Data in /home/user/Linux_Upgrade_Tool_v1.65
Loading loader...
Loading loader failed,err=-2006!

Or maybe there is option to boot idbloader.img located on SD card?

				sudo dd of=$dev if=$UBOOT_FILE bs=1k seek=$UBOOT_START;

			sudo dd of=$dev if=idblock.bin seek=64 conv=notrunc,fsync
			sudo dd of=${dev}1 if=u-boot.itb conv=notrunc,fsync
			set +x
		else
			echo "bpi-r64 with new ATF needs uboot packed into fip!"
		fi
	;;
	"umount")
		umount /media/$USER/BPI-BOOT
		umount /media/$USER/BPI-ROOT
	;;

same to flash idbloader/sdcard to emmc when booted from sdcard
