Part Number: AM3359
Other Parts Discussed in Thread: SYSBIOS
Tool/software: TI-RTOS
Host Env: Windows
BIOS Version: 6.53.2.00
XDCTOOLS: 3.50.03.33
CCS Version: 7.2
I’ve imported the “Static Example” project from the ICE_AM3359 folder and have successfully built and run this project on my development board. At this point I would like to add HW peripherals (SPI, UART, GPIO, etc) but it’s not clear how these modules should be properly added.
As an example, I tried adding the UART peripheral. In this example I just wanted to call the UART_init() routine as seen in the code snippet below. The Error message I receive is the
Undefined reference to ‘UART_init’
Which I assume means that the build is not able to find the source file that includes the UART_init() routine.
Are the different peripherals added and linked correctly using the XGCONF tool?
I’ve looked through a few of the HW examples in the PDK package but it’s not clear how these peripherals were added.
/*
* ======== static.c ========
* The static example focuses on SYS/BIOS configuration. It shows how to
* - Use and configure various modules.
* - Create static Instances.
* - Modify Program level configuration parameters.
