Subject: [PATCH] stm32f469-i: Update kernel start address
|
||||
|
||||
As of GNU/Linux v5.12 kernel device tree binary grows above 0x08008000
|
||||
and overwrites kernel binary
|
||||
Therefore this commit moves kernel to the next flash bank

STM32F469 Discovery
|
||||
===================
|
||||
|
||||
This tutorial describes how to use the predefined Buildroot
|
||||
configuration for the STM32F469 Discovery evaluation platform.
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
make stm32f469_disco_defconfig
|
||||
make
|
||||
|
||||
Flashing
|
||||
--------
|
||||
|
||||
./board/stmicroelectronics/stm32f469-disco/flash.sh output/
|
||||
|
||||
It will flash the U-boot bootloader.
|
||||
|
||||
Creating SD card
|
||||
----------------
|
||||
|
||||
Buildroot prepares an"sdcard.img" image in the output/images/ directory,
|
||||
ready to be dumped on a SD card. Launch the following command as root:
|
||||
|
||||
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
|
||||
|
||||
*** WARNING! This will destroy all the card content. Use with care! ***
|
||||
|
||||
For details about the medium image layout and its content, see the
|
||||
definition in board/stmicroelectronics/stm32f469-disco/genimage.cfg.
|
||||
|
||||
Framebuffer
|
||||
-----------
|
||||
After Linux boots, /dev/fb0 will be accessible. You can control the
|
||||
brightness of the display after enabling the framebuffer by running the
|
||||
following commands:
|
||||
|
||||
# echo 0 0 > /sys/class/graphics/fb0/pan
|
||||
# echo 255 >/sys/class/backlight/40016c00.dsi.0/brightness
|
||||
|
||||
The brightness ranges from 0 to 255, as you can see running the
|
||||
command:
|
||||
|
||||
# cat /sys/class/backlight/40016c00.dsi.0/max_brightness

===================
|

|

This tutorial describes how to use the predefined Buildroot
|

configuration for the STM32F469 Discovery evaluation platform.
|
||||
|
||||
Internal flash memory stores simple afboot-stm32 bootloader, device tree and
|
||||
in place (XIP) kernel with built-in initramfs. No external flash or SD card
|
||||
is needed.
|
||||
|
||||
Kernel is based on tinyconfig.
|
||||
|
||||
Building
|
||||
--------
|

./board/stmicroelectronics/stm32f469-disco/flash.sh output/
|
||||
|
||||
It will flash binary to internal flash memory.
