C6670 Platform UART functions greyed out

Hari..

Hi,

I am working on C6670 UART example project in CCSV6 using EVM6670LE. I see that all the platform functions for UART are greyed out. There is a flag PLATFORM_UART_IN around this code. The example project is running fine on EVM even though the code for UART is greyed out. But on my custom board I don't see any output. I am wondering

1. How does the project work on EVM if the code is greyed out ?

2. How can I enable PLATFORM_UART_IN flag to make the code active ? How can I set this flag in CCS ?

Here are the screenshots for the greyed out code.

Thanks

Hi,

TI example use the platform library driver code to initialize the UART peripheral. The PLATFORM_UART_IN defined in "platform_internal.h" file(\ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_lib\include\).

Better to use the PDK "platform_test" example to test the UART interface on your custom board testing.
Example Path: "\ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_test"
Refer the \ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_test\Readme.txt file, it will help you to run the example.

Thanks,

Thank you Ganapathi. Can you direct me to the platform library driver code where the UART read and write functions are ? I can only see the UART functions in the greyed out code (ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_lib\src\evmc66x_uart.c).

I included the "platform_internal.h" file(\ti\pdk_C6670_1_1_2_6\packages\ti\platform\evmc6670l\platform_lib\include\) and still the code is not active.

Hi,

Platform drive also use the same file/code to initialize the UART.

Refer MCSDK user guide "Example 1 - Building and running a simple single core application" and develop your UART test example for your testing.
