i write a simple code to configure the EIM module, but it seems the configure doesn't work.  i wonder why?

PS: the systerm is in supervisor mode.

Thank you very much!

This sentence basically means that only implemented EIM channel (EICHEN = 0x80000000) can inject error into bus from DMA controller to DMA TCD memory, in other words injected address must be somewhere in DMA TCD area i.e. 0xFC0A1000-0xFC0A13FE.

I am attaching example code.
