| |
| Change settings to fit your needs (optional): |
| |
| $ make menuconfig |
| |
| Compile everything and buildr the rootfs image: |
| |
| $ make |
| |
| |
| Result of the build |
| =================== |
| |
| After building, the output/images directory contains: |
| |
| output/images/ |
| ├── bl31.bin |
| ├── boot.scr |
| ├── ddr_fw.bin |
| ├── Image |
| ├── imx8-boot-sd.bin |
| ├── imx8mq-kontron-pitx-imx8m.dtb |
| ├── lpddr4_pmu_train_fw.bin |
| ├── rootfs.ext2 |
| ├── rootfs.ext4 -> rootfs.ext2 |
| ├── rootfs.tar |

| ├── u-boot.bin |
| ├── u-boot.itb |
| ├── u-boot-nodtb.bin |
| ├── u-boot-spl.bin |
| └── u-boot-spl-ddr.bin |
| |
| |
| 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 |
| * Make sure the boot source selection DIP switches are set correctly |
| * SW1 1-4 OFF |
| * SW1 2-3 OFF |
| * 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 |
