AM2431: AM2434上正常的QSPI引导模式和引导程序,在AM2431上,咋就不行呢

Part Number: AM2431
Other Parts Discussed in Thread: AM2434,

项目开发,前期使用AM2434,用QSPI模式引导,使用GD25Q16E Flash开发的引导程序,可以在自己设计的板子上正常启动,并加载运行APP。现在换成AM2431芯片,同样的硬件,就无法引导,更不能加载APP,请问这是什么问题。

之前,已把SBL调试程序写入Flash的0x600000000,调试时,即使加载SBL程序,也会进入0x418xxxxx地址,感觉是MCU根本不认识启动模式设置,请问这是什么原因。

另外,读回来的BootMode Status(0x43000030)=0x00000d13,BootMode Config(0x43000034)=0x00000d13,说明外部配置的启动Pin脚,也确实指向了QSPI Flash
