Building
|
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
|
|
Configure buildroot:
|
|
|
|
|
|
|
|
|
|
|
|
$ make imx8mn_bsh_smm_s2_defconfig
|
|
|
|
|
|
|
|
|
|
|
|
Change settings to fit your needs (optional):
|
|
|

|
|
|
|
|
|
$ make menuconfig
|
|
|
|
|
|
|
|
|
|
|
|
Compile everything and build the rootfs image:
|
|
|
|
|
|
|
|
|
|
|
|
$ make
|
|
|
|
|
|
|

Preparing the board
|
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
|
|
Plug the USB type A to micro B cable into the USB Debug
|
|
|
|
|
|
Connector (DBG UART). Use serial port settings 115200 8N1
|
|
|
|
|
|
to access the debug console.
|
|
|
|
|
|
|
|
|
|
|
|
Plug another USB type A to micro B cable into the USB-OTG
|
|
|
|
|
|
Connector (USB1). This connection is used to flash the board
|
|
|
|
|
|
firmware using the Freescale/NXP UUU tool.
|
|
|
|
|
|
|
|
|
|
|
|
Connect the power supply/adaptor to the DC Power Jack (labelled
|
|
|
|
|
|
+5V).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Flashing
|
|
|
|
|
|
--------
|
|
|
|
|
|
|
|
|
|
|
|
Power up the board by switching on the Power ON Switch, which is
|
|
|
|
|
|
placed right next to the DC Jack.
|
|
|
|
|
|
|
|
|
|
|
|
Enter the following U-Boot commands on the debug serial console:
|
|
|
|
|
|
|
|
|
|
|
|
$ nand erase.chip
|
|
|
|
|
|
$ reset
|
|
|
|
|
|
|
|
|
|
|
|
Flash the built images directly to board’s memory. On your computer,
|
|
|
|
|
|
run:
|
|
|
|
|
|
|
|
|
|
|
|
$ board/bsh/imx8mn-bsh-smm-s2/flash.sh output/
|
|
|
|
|
|
|
|
|
|
|
|
It will flash the bootloader, the Device Tree Blob, the kernel image
|
|
|
|
|
|
and the UBI root file system.
