Part Number:LAUNCHXL-CC2650
Tool/software:TI-RTOS
Hello, I am trying to get my launchpad to print text over UART via the System_printf function. I have followed the directions at the following website. ![]()
I changed the .cfg file to include references to the uart putch function and uartfluch function. Below is my cfg file:
/******************************************************************************
@file cc2640.cfg
@brief TI RTOS Configuration file for CC26xx
Imported Symbols
Note: These symbols are defined following the --cfgArgs option.
In IAR this is done at the end of the pre-build step. In CCS, this
is done in Properties->build->XDCtools-Advanced options->Configuration
script arguments. Multiple symbols can be used separating them by a
comma (",").
By default, TI RTOS builds with RTOS in ROM, interrupt vectors starting
at address 0x0 and uses ROM only kernel modules.
NO_ROM: When set to a non-zero value, RTOS builds in Flash instead
of ROM
OAD_IMG_A: When set to a non-zero value, interrupt vectors are set to
their expected location for on-chip OAD Image A.
OAD_IMG_B: When set to a non-zero value, interrupt vectors are set to
their expected location for on-chip OAD Image B.
OAD_IMG_E: When set to a non-zero value, interrupt vectors are set to
their expected location for external flash OAD.
USE_EVENTS: Build the RTOS Kernel Event module.
Group: WCS, BTS

It seems like the UART is setup fine, you can see in my setupUART() function that I directly write to it. That wI can see on PuTTy, but System_printf() is not working for some reason. Any advice on where to look/start would be helpful. I have read a lot on this forum but nothing that has helped me directly.
I am using tirtos_cc13xx_cc26xx_2_20_01_08, and ble_sdk_2_02_01_18.
I am developing with CCS Version 6.1.3.00034, and compiler TI v15.12.5.LTS
Thanks!
