Header file not working

Other Parts Discussed in Thread: LM3S8962, EK-LM3S8962

I have been working on a prgram on CAN bus with my LM3S8962 MCU kit. The program which I was trying was an example program given along with the software CD. While compiling the program I got the following errors.

unresolved symbol UARTprintf, first referenced in ./simple_tx.obj sid line 0 1278823057808 20

unresolved symbol UARTStdioInit, first referenced in ./simple_tx.obj sid line 0 1278823057807 19

I am sure that I have included the header for UARTprintf and the utilities files for UART StudioInit. I specifically mentioned the path for those two files, but still it dint work.

I dint tamper with the header files or with the utilities file in the CD.

What could be the possible solution for this problem.

What example application did you start with and where did you make the modifications to include the UARTprintf, etc.?

HI Barandon,

I was working with CAN-multi Tx program given in the Stellarisware Examples.

I copied the necessery files from C:/Stellarisware to E:/CCSworkbench/"myfilename".

The same procedure worked for another program which did not require UARTprintf function.

Well I am sorry the program was CAN Simple_tx

I'm stumped. I don't find any such example. Which directory are you referencing under StellarisWare\boards\ek-lm3s8962?

I am talking about the example program in Stellarisware/examples/peripherals/can/simple_Tx...

UARTprintf and UARTStdioInit are defined in uartstdio.c, so this source file also needs to be added to the project to avoid those linker errors. Go to Project->Add Files to Project, and browse to C:\StellarisWare\utils and select the file uartstdio.c to add to project.
