Sample programs fail

Tommy44 — Thu, 14 Feb 2013 02:56:09 GMT

I have two FRDM-KL25 boards, I installed CW 10.3 and The Kinetis L sample code. Using the instructions in the FRDM-KL25Z-QSP document I compiled and ran the hello-world application without incident. When I try the other samples in the same folder they all fail with errors like:

Description Resource Path Location Type

ARM_GCC_Support/ewl/EWL_C/src/sys/uart_console_io.c undefined reference to `WriteUARTN' accelerometer_demo line 151 C/C++ Problem

or:

Description Resource Path Location Type

mingw32-make: *** [accelerometer_demo.elf] Error 1 accelerometer_demo C/C++ Problem

Sample programs that fail are never a good sign. Can I expect an update soon?

Hi,

KL25_sc provides CW examples using Processor Expert (PEx) tool, one of this examples is accelerometer_demo which is in projects folder. PEx projects needs to generate the code for each component. That is why CW compiler does not find some UART functions or others.

You need to Generate Processor Expert Code:

Click on Generate Processor Expert Code button.

2. Wait......

3. Compile again.

Hope this helps.

I needed the Community Development License for PE to work, once I found

that all is well.

Also, the reason WriteUARTN() is required is because of the ANSI library. Erich has a great post discussing using the ANSI library in CW10 at this link:
