- How to use U-Boot on NXP i.MXRT1020 EVK
- -----------------------------------------------
- - Build U-Boot for i.MXRT1020 EVK:
- $ make mrproper
- $ make imxrt1020-evk_defconfig
- $ make
- This will generate the SPL image called SPL and the u-boot.img.
- - Flash the SPL image into the micro SD card:
- sudo dd if=SPL of=/dev/sdX bs=1k seek=1; sync
- - Flash the u-boot.img image into the micro SD card:
- sudo dd if=u-boot.img of=/dev/sdX bs=1k seek=128; sync
- - Jumper settings:
- SW8: 0 1 1 0
- where 0 means bottom position and 1 means top position (from the
- switch label numbers reference).
- - Connect the USB cable between the EVK and the PC for the console.
- (The USB console connector is the one close the ethernet connector)
- - Insert the micro SD card in the board, power it up and U-Boot messages should
- come up.
