那你是怎么解决的啊？
我的问题是由硬件看门狗引起的。看门狗周期性地复位DSP ,DSP连上仿真器后提示locked。也就是说DSP没有成功复位……
所以我建议你先查一下DSP的复位信号。
The first routine called after reset is the InitBoot assembly routine. This routine initializes the device for
operation in C28x object mode. InitBoot also performs a dummy read of the Code Security Module (CSM)
password locations. If the CSM passwords are erased (all 0xFFFFs) then this has the effect of unlocking
the CSM. Otherwise the CSM will remain locked and this dummy read of the password locations will have
no effect. This can be useful if you have a new device that you want to boot load.
