This commit adds a minimal defconfig to build a Buildroot system for the STM32MP157 Discovery Kit, which is the low-cost evaluation platform for the new STM32MP157 system-on-chip from ST. This system-on-chip features a single or dual Cortex-A7, a single Cortex-M4, and a wide variety of peripherals. This commit includes a custom linux configuration file, because there is no specific defconfig for this platform in the kernel, only multi_v7_defconfig supports it, which is really a massive defconfig. That's why a custom linux configuration file is added. A small U-Boot config fragment allows to disable the watchdog, so that userspace by default doesn't need to have a watchdog daemon running. The vendor U-Boot and Linux trees are used for the moment, but the platform support is being upstreamed, so switching to upstream versions will be possible in the relatively near future.

How to build
|
|
============
|
|
|
|
$ make stm32mp157_dk_defconfig
|
|
$ make
|
|
|
|
How to write the microSD card
|
|
=============================
|
|
|
|
Once the build process is finished you will have an image called
|
|
"sdcard.img" in the output/images/ directory.
|
|
|
|
Copy the bootable "sdcard.img" onto an microSD card with "dd":
|
|
|
|
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
|
|
|
|
Boot the board
|
|
==============
|
|
|
|
(1) Insert the microSD card in connector CN15
|
|
|
|
(2) Plug a micro-USB cable in connector CN11 and run your serial
|
|
communication program on /dev/ttyACM0.
|
|
|
|
(3) Plug a USB-C cable in CN6 to power-up the board.
|
|
|
|
(4) The system will start, with the console on UART, but also visible
|
|
on the screen.
