Part Number: AM2634

I would like to test dio_app and get pass log:

But i don't know how to mapping the IO with real PIN :

Ex. Dio_ReadChannel(64) in DioApp.c

64 refers to which PIN??

Thanks for your help.

Hi @Jay Sun

The mapping is clearly present in the datasheet document(Not the TRM) of the AM2634, you can find it here AM263x Sitara Microcontroller datasheet (Rev. B) (ti.com)

Just search for the pin number by adding the pre-fix GPIO to the channel number and you should find the ball mapping done

Thanks

I still can't find the mapping between Port_PinId and Port_PinSignalName as below.

Please help to point out.

Thanks for your help.

Hi,

The port pin ID is not related in anyway to the TI's pin descriptions. The MCAL made this as a simple logical numbering. These are not available for the user to configure through the EB tresos, user can simply choose the pin name and this field is auto-filled.

Thanks
