This does not work...:(

When I first imported this I got an error that "device.h" does not exist. I imported mbed-src and that error went away but was replaced by an error that the K22F platform is not supported RTX_Conf_CM.c, which I also get when I import the same project from within the compiler.

I *NEED* mbed-rtos to work on this platform for a product we are developing now.

Question relating to:

Last updated: 07 Apr 2014
Basic example usage of mbed RTOS (complete) Created for FTF2014. FTF2014, hands-on, lab

Hmmm...I successfully exported this to Kinetis Design Studio format and imported it into my workspace. However, when I build, I get an error: Description Resource Path Location Type undefined reference to `rt_get_PSP' rt_Task.c /frdm_rtos_K22F/mbed-rtos/rtx/TARGET_CORTEX_M line 252 C/C++ Problem

Odd that I got it in the export, but didn't see that error when I compiled from mbed. Any thoughts?

Go to this file in your imported mbed-rtos: http://developer.mbed.org/users/mbed_official/code/mbed-rtos/file/318e02f48146/rtx/TARGET_CORTEX_M/RTX_Conf_CM.c. Then add TARGET_K22F next to all TARGET_K64F and it should work fine. Should be added to official one too, but I can't do it currently until someone accepts another pull request :).

Well, I had to chase down another file as well. I made progress, but got a more scary error now:

Error: "/extras/mbed_031413cf7a89/TARGET_K22F/TOOLCHAIN_ARM_STD/MK22F51212.sct", line 4 (column 9): Error: L6235E: More than one section matches selector - cannot all be FIRST/LAST.

Per response below--

Yes. I had imported the source for mbed-src per another thread and evidently it can't co-exist with the mbed-rtos. Is the full mbed library contained in the mbed-rtos folder?

THANKS!

First of all, missed that you also have to supply the initial_sp, not a clue why it can't just get the one from the CMSIS files, but okay. This one is different than the K64F, it is for the K22F:

#elif defined(TARGET_K22F)
#define INITIAL_SP            (0x20010000UL)

If I then compile it is succesfull (also with different initial_Sp, but then it won't actually work).

Regarding your error: Do you maybe have a library imported twice?
