Hello,
I was trying to use the UART printf function, but I receive unresolved symbol errors.
For back ground reference, I am working on Tiva-C workshop lab 12 starting on step 20 (https://engineering.purdue.edu/ece477/Archive/2014/Spring/S14-Grp1/docs/software/LM4F-LaunchPad-12%20-%20UART.pdf).
This my current software versions:
- CCS v6.2.0.00050
- Compiler Version: TI v15.12.6.LTS
- TivaC Version: 2.16.1.14
- XDCtools version: 3.32.1.22_core
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__".
