CCS/TM4C123GH6PM: Unresolved symbol UARTprintf and UARTStdioInit (error #10234-D)

See this post from Aarti:
e2e.ti.com/.../197468

Note that in your environment, the location of uartstdio.c is:
C:\ti\tirtos_tivac_2_16_01_14\products\TivaWare_C_Series-2.1.1.71b\utils

Thanks

Hi Ki,

Thank you for responding so quickly.

I copied the uartsdio.c file to my project, but I received similar errors (build log below). I even tried to add the address of the "utils" folder to my Include Options (ARM Compiler) and File Search Path (ARM Linker), but those did not work.

I do want to note that I was unable to find UARTStdioInit() in the uartsdio.c file which means it may not be calling anything. I have never edited the file before and I have seen the function used in examples online. Has TI changed how UART functions are enabled?

hmmm, yes I don't see it defined in uartstdio.c either. I searched the tivaware directory and was unable to find it. The experts in the TM4C forums would know. I suggest starting a new thread there.

After reading the documentation in uartstdio.c, I've discovered that calling UARTStdioConfig() is how I can enable UART and be able to use UARTprintf(). My code already has this config called so now I'm left with one unsolved symbol: "__error__".
