There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.This page explains how to configure the U-Boot source for your board.
1. introduction[edit source]
Ressources [1] [2] already explain the porting U-Boot on a new board, this page is only a basic guideline.
To summarize, you need to configure U-Boot:
- add your board #device tree
- add TARGET_<board> in #Kconfig
- create your own board support subdirectory
- add your #config file
- create your board #defconfig
2. device tree[edit source]
See U-Boot_overview#Device_tree for details.
- copy the kernel device tree in arch/arm/dts directory: <board>.dts
- update arch/arm/dts/Makefile to compile your device tree, for example:
dtb-$(CONFIG_STM32MP15x) += \ <board>.dtb
- add a U-Boot devicetree for your board n arch/arm/dts directory: <board>-u-boot.dtsi
This file with all the U-Boot update on kernel device tree is automatically inlcude during <board>.dts
At this point you can already check boot using the generic ST defconfig with the ST board.
For example, on STM32PM15
But board specific could be not correctly managed.
