NXP i.MX 8M Plus Evaluation Kit (``imx8mp-evk``)
|
|
================================================
|
|
|
|
The ``imx8mp-evk`` machine models the i.MX 8M Plus Evaluation Kit, based on an
|
|
i.MX 8M Plus SoC.
|
|
|
|
Supported devices
|
|
-----------------
|
|
|
|
The ``imx8mp-evk`` machine implements the following devices:
|
|
|
|
* Up to 4 Cortex-A53 cores
|
|
* Generic Interrupt Controller (GICv3)
|
|
* 4 UARTs
|
|
* 3 USDHC Storage Controllers
|
|
* 1 Designware PCI Express Controller
|
|
* 1 Ethernet Controller
|
|
* 2 Designware USB 3 Controllers
|
|
* 5 GPIO Controllers
|
|
* 6 I2C Controllers
|
|
* 3 SPI Controllers
|
|
* 3 Watchdogs
|
|
* 6 General Purpose Timers
|
|
* Secure Non-Volatile Storage (SNVS) including an RTC
|
|
* Clock Tree
|
|
|
|
Boot options
|
|
------------
|
|
|
|
The ``imx8mp-evk`` machine can start a Linux kernel directly using the standard
|
|
``-kernel`` functionality.

Direct Linux Kernel Boot

|
Probably the easiest way to get started with a whole Linux system on the machine
|
|
is to generate an image with Buildroot. Version 2024.11.1 is tested at the time
|
|
of writing and involves two steps. First run the following commands in the
|
|
toplevel directory of the Buildroot source tree:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ make freescale_imx8mpevk_defconfig
|
|
$ make
|
|
|
|
Once finished successfully there is an ``output/image`` subfolder. Navigate into
|
|
it and resize the SD card image to a power of two:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ qemu-img resize sdcard.img 256M
|
|
|
|
Now that everything is prepared the machine can be started as follows:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ qemu-system-aarch64 -M imx8mp-evk -smp 4 -m 3G \
|
|
-display none -serial null -serial stdio \
|
|
-kernel Image \
|
|
-dtb imx8mp-evk.dtb \
|
|
-append "root=/dev/mmcblk2p2" \
|
|
-drive file=sdcard.img,if=sd,bus=2,format=raw,id=mmcblk2
