Kontron pitx-imx8m
|
||||
==================
|
||||
|
||||
https://www.kontron.com/produkte/pitx-imx8m/p155258
|
||||
|
||||
|
||||
How to build it
|
||||
===============
|
||||
|
||||
Configure buildroot:
|
||||
|
||||
$ make kontron_pitx_imx8m_defconfig
|
||||
|
||||
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
|
||||
├── sdcard.img
|
||||
├── signed_hdmi_imx8m.bin
|
||||
├── 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
