Hello:  
Recently, I began to contact the development of R5 core in Xavier. Although I found the TRM and demos of SPE, I could not find the hardware pin number corresponding to R5 resource. where can I get relevant information of this part?

No such pins are exposed out to module connector, all the pins available are listed in pinmux and design guide, please check that.
