【RV1103】如何新增一个新板级配置

文章目录

新建一个板级配置文件

新建一个板级配置文件

我的目标

通过./build.sh lunch 来选择我的板子配置。

在目录sdk/project/cfg目录下新建一个xxxx.mk文件，文件名字格式如下：

bash 复制代码

BoardConfig-"启动介质"-"电源方案"-"硬件版本"-"应用场景".mk

bash 复制代码

----------------------------------------------------------------
0. BoardConfig_IPC/BoardConfig-EMMC-NONE-RV1103_Luckfox_Pico-IPC.mk
                             boot medium(启动介质): EMMC
                          power solution(电源方案): NONE
                        hardware version(硬件版本): RV1103_Luckfox_Pico
                              applicaton(应用场景): IPC
----------------------------------------------------------------

----------------------------------------------------------------
1. BoardConfig_IPC/BoardConfig-SPI_NAND-NONE-RV1103_Luckfox_Pico_Plus-IPC.mk
                             boot medium(启动介质): SPI_NAND
                          power solution(电源方案): NONE
                        hardware version(硬件版本): RV1103_Luckfox_Pico_Plus
                              applicaton(应用场景): IPC
----------------------------------------------------------------

BoardConfig-EMMC-NONE-RV1103_Luckfox_Pico-IPC.mk
BoardConfig-SPI_NAND-NONE-RV1103_Luckfox_Pico_Plus-IPC.mk

- 作为大区分
_作为字符串内部的区分

而我的目标是，在板子RV1103_Luckfox_Pico的基础上加入了，sd卡、sdio-wifi卡和spi-nand Flash，故我取了一个名字

BoardConfig-SPI_NAND-NONE-RV1103_Luckfox_Pico_Pro-SD_WIFI_IPC.mk

脚本解析出来是：

bash 复制代码

----------------------------------------------------------------
2. BoardConfig_IPC/BoardConfig-SPI_NAND-NONE-RV1103_Luckfox_Pico_Pro-SD_WIFI_IPC.mk
                             boot medium(启动介质): SPI_NAND
                          power solution(电源方案): NONE
                        hardware version(硬件版本): RV1103_Luckfox_Pico_Pro
                              applicaton(应用场景): SD_WIFI_IPC
----------------------------------------------------------------

它的主要内容

bash 复制代码

#!/bin/bash

# Target arch
export RK_ARCH=arm

# Target CHIP
export RK_CHIP=rv1106

# Target Toolchain Cross Compile
export RK_TOOLCHAIN_CROSS=arm-rockchip830-linux-uclibcgnueabihf

# Target boot medium: emmc/spi_nor/spi_nand
export RK_BOOT_MEDIUM=spi_nand

# Uboot defconfig
export RK_UBOOT_DEFCONFIG=rv1106_defconfig

# Uboot defconfig fragment
export RK_UBOOT_DEFCONFIG_FRAGMENT=rk-sfc.config

# Kernel defconfig
export RK_KERNEL_DEFCONFIG=luckfox_sd_wifi_rv1106_linux_defconfig

# Kernel dts
export RK_KERNEL_DTS=rv1103g-luckfox-pico-pro.dts

plus板设备树的继承关系：

rv1103g-luckfox-pico-pro.dts相对于rv1103g-luckfox-pico-plus.dts的主要修改：
