How to use U-Boot on MYiR MYS-6ULX Single Board Computer
|
|
--------------------------------------------------------
|
|
|
|
- Configure and build U-Boot for MYS-6ULX iMX6ULL:
|
|
|
|
$ make mrproper
|
|
$ make myir_mys_6ulx_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 -> 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 proper 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 -> 1
|
|
SW2 -> 0
|
|
SW3 -> 0
|
|
SW4 -> 1
|
|
|
|
- Connect the Serial cable to UART0 and the PC for the console.
|
|
|
|
- Reset the board using and U-Boot should boot from NAND.
