| How to build it |
| =============== |
| |
| Configure buildroot: |
| |
| $ make kontron_bl_imx8mm_defconfig |
| |
| Change settings to fit your needs (optional): |
| |
| $ make menuconfig |
| |
| Compile everything and build the rootfs image: |
| |
| $ make |
| |
| |
| Result of the build |

| Flashing the SD card image |
| ========================== |
| |
| To install the image on a SDCard simply copy sdcard.img to the storage (e.g. SD, eMMC) |
| |
| $ sudo dd if=output/images/sdcard.img of=<your-sd-device> |
| |
| |
| Preparing the board |
| =================== |
| |
| * Connect a serial line to the board |
| * Insert the SD card |
| * Power-up the board |
| |
| |
| Booting the board |
| ================= |
| |
| By default the bootloader will search for the first valid image, starting |
| with the internal eMMC. To make sure the bootloader loads bootscript from |
| the correct location (SD card) set the boot_targets environment variable: |
| |
| $ setenv boot_targets mmc1 |
