How to use U-BOOT on SeeedStudio NPI-IMX6ULL Single Board Computer
------------------------------------------------------------------
- Configure and build U-Boot for NPI-IMX6ULL:
$ export ARCH=arm
$ export CROSS_COMPILE=arm-none-linux-gnueabihf-
$ make seeed_npi_imx6ull_defconfig
$ make
This will generate SPL and u-boot-dtb.img images.
Boot from MMC/SD:
- The SPL and u-boot-dtb.img images need to be flashed into the micro SD card:
$ sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
$ sudo dd if=u-boot-dtb.img of=/dev/mmcblk0 bs=1k seek=69; sync
- Boot mode settings:
Boot switch position: SW1 -> 0
SW2 -> 1
SW3 -> 0
SW4 -> 0
SW5 -> 1
SW6 -> 0
SW7 -> 0
SW8 -> 1
Boot from NAND:
- Boot the board using SD/MMC or Serial download and load the SPL into memory
either from SD/MMC or TFTP.
Default MTD layout is 512k(spl),1m(uboot),1m(uboot-dup),-(ubi)
Flash SPL to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr SPL
$ nand erase.part spl
$ nandbcb init $loadaddr 0x0 $filesize
Flash u-boot image to NAND from SD/MMC,
$ ext4load mmc 0:2 $loadaddr u-boot-dtb.img
$ nand erase.part uboot
$ nand write $loadaddr uboot $filesize
- Boot mode settings:
Boot switch position: SW1 -> 0
SW2 -> 1
SW3 -> 1
SW4 -> 0
SW5 -> 0
SW6 -> 1
SW7 -> 0
SW8 -> 0
- Connect the Serial cable to UART0 and the PC for the console.
- Reset the board using reset button and U-Boot should boot from NAND.
