NXP i.MX8MN DDR4 EVK
====================
This is a Buildroot target for building an image for the imx8mn-ddr4-evk
board using upstream components: TF-A, U-Boot and kernel.
How to build it
===============
Configure Buildroot and build it:
$ make imx8mn-ddr4-evk_defconfig
$ make
Flashing the SD card image
==========================
Copy the sdcard.img file into the SD card:
$ sudo dd if=output/images/sdcard.img of=<your-sd-device>; sync
Booting the board
=================
To boot your newly created system:
- Insert the SD card in the MicroSD slot of the board.
- Connect a serial to USB cable to the DEBUG port.
- Open a terminal on ttyUSB2 port. For example: sudo picocom -b 115200 /dev/ttyUSB1
- Power on the board.
