When using cygwin64 "dd (coreutils) 8.26 Packaged by Cygwin (8.26-2)", the last not 512bytes aligned data wat cut off and not burned into SD card. Saying the flash.bin size is 1085608 bytes, not 512bytes aligned. It only burned 1085440 bytes, the leaving 168 bytes were not burnned and cause boot issue. So update README dd command to add "conv=notrunc" Signed-off-by: Peng Fan <peng.fan@nxp.com> |

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 conv=notrunc; 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 conv=notrunc; 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.
