错误信息 #

构建自定义配方m4examples.bb时出现以下内核链接错误：

ld: drivers/input/touchscreen/edt-ft5x06.o: in function `edt_ft5x06_ts_probe':

解决思路 #

1. 启用内核MIPI DSI相关配置 #

of_find_mipi_dsi_device_by_node是MIPI DSI子系统的API，需确保内核配置中开启对应选项：

• 执行bitbake -c menuconfig virtual/kernel进入内核配置界面
• 找到并启用CONFIG_DRM_MIPI_DSI（路径：Device Drivers > Graphics support > DRM support > MIPI DSI support）
• 若edt-ft5x06驱动依赖其他MIPI相关模块，同步开启对应配置

2. 检查驱动编译配置 #

• 确认edt-ft5x06驱动的Makefile中包含正确编译规则，如obj-$(CONFIG_TOUCHSCREEN_EDT_FT5X06) += edt-ft5x06.o
• 检查驱动源码是否包含必要头文件：#include <drm/mipi_dsi.h>，确保API声明被正确引入

3. 校验内核源码一致性 #

• 确认linux-stm32mp-argon内核版本与meta层（如meta-st-stm32mp）版本匹配，避免因API变更导致函数缺失
• 若有自定义内核补丁，检查是否误删了MIPI DSI子系统的函数实现代码

4. 排除自定义配方干扰 #

• 检查m4examples.bb是否修改了内核编译参数（如CFLAGS/LDFLAGS）或内核配置，这类修改可能破坏链接流程
• 尝试单独构建内核：执行bitbake virtual/kernel -c clean && bitbake virtual/kernel，若仍报错则问题与配方无关，需聚焦内核本身排查
