CCS/CC2640R2F: Converting uart example from launchpad to RSM packaging

Andrew Parker

Part Number: CC2640R2F

Tool/software: Code Composer Studio

Using SDK: 4.20.00.04
Example project: Uartecho

What needs to be configured in board.h, CC2640R2_LAUNCHXL.h, CC2640R2_LAUNCHXL.c, and CC2640R2_LAUNCHXL_fxns.c in order for the uart echo example to work on a 4x4mm RSM package CC2640R2?

I am aware that the RSM package only has 10 pins and goes up to DIO9. When I set the rest of the pins to PIN_UNASSIGNED and comment out references to unused pins in CC2640R2_LAUNCHXL_fxns.c, my code runs but I don't see anything coming out of the pins. I can step through the code and see the code successfully reach the uart read portion. I don't see anything from the TX stating the opening message either.

See http://dev.ti.com/tirex/explore/node?node=ALM94yP81AH0tbI4q55oQg__krol.2c__LATEST on a general guide to make a board file.

Meaning that what you need to do is setting all pins that you don't have on a RSM in CC2640R2_LAUNCHXL.h to PIN_UNASSIGNED. I don't believe you should have to set anything else since the UART in the board file is already mapped to existing DIOs (DIO2 and DIO3)

Do you use a logic analyzer/ scope to monitor the UART pins? If not, how have you connected the UART pins to verify that the UART work or not?

I found out the issue, it was a pin configuration/reading the schematic wrong.
