Hi!
我使用的芯片是DM3730,我运行APP的时候,出现“DSP MMU Error Fault! MMU_IRQSTATUS = [0x1]. Virtual DSP addr reference that generated the interrupt = [0x8c2000e0].”
我的内存分配是:
var mem_ext = [

我查阅了processors.wiki.ti.com/.../DSP_MMU_Faults
我对“the memory range to map to the DSP MMU”是指什么内存啊?我该怎么解决这个问题尼?
希望能尽快回复,感谢万分!

您好:
我也碰到了类似的问题。您知道该怎么去修改吗?直接或者间接的解决问题?
