DDR addr bus test:can'taccess memory @ 0xc0000004PANIC at PC : 0x2ffe5db1Exception mode=0x00000016 at: 0x2ffe5db1 从硬件设计的角度看,目前软件配置所涉及到的硬件区别主要是供电部分,采用分离式电源,板子一上电,每一个DC-DC均有输出,不需要软件控制,也就是说,只要板子上电,DDR供电就已经存在了;...
This field must be between 0 and 255 and defines the scaler factor for generating the CLK based on the kernel clock (value + 1). In STM32CubeMX, the Clock Prescaler must be between 1 and 256. In this case the Clock Prescaler = (PRESCALER[7:0]: Clock prescaler)+ 1 Please see ...
