Pinouts of SPI4 on TMDXRM46HDK Hercules Development Kit

Other Parts Discussed in Thread: TMDXRM46HDK, HALCOGEN

Hi, I am using TMDXRM46HDK Hercules Development Kit. I have configured and tested SPI2 with Aardvark and it is working fine.

I have configured SPI4 as well but I am unable to test it. Can you please suggest how can i test SPI4 with Aardvark?

Are there pin-outs available of SPI4 as I could not locate SPI4_CLK signal? 

If SPI4 couldn't be tested with Aardvark, how can i test SPI4?

Thanks

    Hi Naveed,

    SPI4 is only available as a multiplexed option on the RM46x MCUs. These signals are available on the following terminals, as listed in the datasheet (spns185).

    You need to configure the I/O multiplexing control registers in order to allow these SPI4 signals to be output on the assigned terminals. You can generate source code to do that using HALCoGen.

    I also noted that the HDK schematic (part of spnr032) shows the multiplexed signals as NHET1[00]/SPI2CLK. This is a mistake and the correct name is NHET1[00]/SPI4CLK. We will correct the schematic to reflect this.

    Regards,

    Sunil
