我正在尝试为特定的
STM32MP157
开发板构建 Yocto-Linux。我正在使用“thud”,但现在需要“dunfell”,因为它应该是长期稳定的。
系统是按照ST的手册搭建的:
https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine
tf-a-stm32mp-2.2
u-boot-stm32mp-2020.01
设备树已修改,Bitbake 正在对其进行编译。但是现在系统在执行 TF-A 引导(从 SD)时卡住了。
有什么方法可以调试或获取图像加载失败的原因吗?
当我尝试通过 STProgrammer 刷新它时,出现“PC 恐慌”。
在此先感谢您的任何建议!
