Hello,

I am new to CCS IDE & using CC3220SF-LAUNCHXL and doing some basic experiments like GPIO, ADC,DAC, PWM, LCD,RTC and UART.

Every experiment I have successfully completed.

But while doing UART experiment I am getting the following error

“Description Resource Path Location Type #10010 errors encountered during linking; "demo5_UART.out" not built demo5_UART C/C++ Problem”
“Description Resource Path Location Type
href="processors.wiki.ti.com/.../10234"> unresolved symbols remain demo5_UART C/C++ Problem”
“Description Resource Path Location Type unresolved symbol main, first referenced in C:\ti\ccsv7\tools\compiler\ti-cgt-arm_16.9.1.LTS\lib\rtsv7M4_T_le_eabi.lib<args_main.obj> demo5_UART C/C++ Problem”

The error is not in the program but some other error while linking.

I am using CCS V_7.1.0 & SDK version simplelink_cc32xx_sdk_3_10_00_04

I have followed the following procedure for doing the experiment. I have also attached screen shots in attachments

Create CCS project using following configuration

I have selected the board as CC3220SF, debugger as TI XDS110 USB Debug Probe.

Then I have added necessary libraries as

The following in the include options under ARM compiler
1. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\kernel\nortos"
2. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\kernel\nortos\posix"
3. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\source"
4. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\source\ti\devices\cc32xx\driverlib"
5. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\source\ti\devices\cc32xx\inc"
6. "C:\ti\simplelink_cc32xx_sdk_3_10_00_04\source\ti\drivers\uart"

The following in the File search path under ARM Linker
"C:\ti\simplelink_cc32xx_sdk_3_10_00_04\source\ti\devices\cc32xx\driverlib\ccs\Release\driverlib.a"

The Program I am using is as follows

#include "rom.h"

#include "rom_map.h"

#include "hw_memmap.h"

#include "hw_common_reg.h"

#include "hw_types.h"

#include "hw_ints.h"

#include "uart.h"

#include "interrupt.h"

#include "utils.h"

#include "prcm.h"

unsigned int i;

#include "pin_mux_config.h"

unsigned char msg[]={"Embedded LAB - UART Demo"};

voidmain()

{

PinMuxConfig();

UARTConfigSetExpClk(UARTA1_BASE, PRCMPeripheralClockGet(PRCM_UARTA1), 115200,

(UART_CONFIG_WLEN_8 | UART_CONFIG_STOP_ONE | UART_CONFIG_PAR_NONE));

while(1)

{

for(i=0; msg[i]!='\0'; i++)

UARTCharPut(UARTA1_BASE, msg[i]);

UARTCharPut(UARTA1_BASE,0x0D);

UARTCharPut(UARTA1_BASE,0x0A);

UtilsDelay(8000000);

}

I have also generated pin_mux_config.h & pin_mux_config.c using PINMUX tool for which screen shot is as follows

And then downloaded the pin_mux_config.h & pin_mux_config.c and added them in program.

After building my project I am getting no errors in the program but only errors for linking only which I have mentioned above in the document. The screen shot of the error are in attachments.

I have also attached pin_mux_config.h & pin_mux_config.c in the attachments.

Note:- The above mentioned procedure I have followed for other experiments and they work just fine. I have tried other versions of the compilers and the other sdk version simplelink_cc32xx_sdk_3_20_00_06 but I am getting the same error. I have also added a word file mentioning the above data & error.UART_error.docx

Kindly guide me.

Rajeev,

The issue is that in your main.c, you are missing a space between void and main().
The linker is generating the error because it sees this function name as voidmain instead of the main that it is expecting.
