| How to use U-Boot on Freescale MX6SXSCM boards |
| ---------------------------------------------- |
| |
| - Build U-Boot for MX6SXSCM EVB board*: |
| |
| $ make mx6sxscm_1gb_evb_defconfig |
| $ make |
| |
| This will generate the u-boot image u-boot.imx. |
| |
| - Flash the u-boot image into the micro SD card: |
| |
| sudo dd if=u-boot.imx of=/dev/sdX bs=1k seek=1; sync |
| |
| *Other defconfigs availabe are: |
| mx6sxscm_1gb_evb_defconfig |
| mx6sxscm_1gb_evb_m4fastup_defconfig |
