Can't link to mmcau_lib.a

corya_ — Fri, 18 Jan 2013 18:13:58 GMT

Hello,

I'm trying to use the mmcau_lib.a contained in the CAU_MMCAU_SW.zip from Freescale.

I'm using a K70 tower board, which has the mmCAU.

I've followed the guidance in the CAU API User's Guide such as:

#define FREESCALE_MMCAU

I get compiler errors in debug, which looks to be expected since the lib is in .a format.

However, I also get an error when I try to run the code from flash. Here is the specific error:

**** Build of configuration MK70FN1M0_INTERNAL_FLASH for project K70CryptoCyclonemax ****

C:\Freescale\CW MCU v10.2\gnu\bin\mingw32-make -j8 all

C:/Freescale/CW MCU v10.2/MCU/ARM_Tools/Command_Line_Tools/mwldarm|Linker|Error

I have the cau_api.h in my source files, which has the function prototype for cau_des_encrypt as well as

#define cau_des_encrypt

mmcau_des_encrypt

Any ideas or suggestions?

Thanks!

Cory

Once I added the mmcau_lib.a in the manner shown below, I am able to compile, link and program the Kinetis K70 with the cau lib.

Here is what I did in CodeWarrior 10.2:

In the CW workspace, right click on the project folder and go to properties.

Under "C/C++ Build" open "Settings"

Under "ARM Linker" click on "Input"

Add the mmcau_lib.a in the "Additional Libraries" window.

Good luck!

Cory, this means it works now? :smileygrin:

That is AWESOME!

PS sorry for the delay on answering your post

For those using the GCC in CW 10.3, the process is slightly different:

In the CW workspace, right click on the project folder and go to properties.

Under "C/C++ Build" open "Settings"

Under "ARM Ltd Windows GCC C Linker" click on "Miscellaneous"

Add the mmcau_lib.a in the "Other objects" window.

Good luck!

I just tried this in CW10.6 with a C++ project, and it works as well. I'm using K70. Since mine is C++, I added this to "ARM Ltd Windows GCC C++ Linker":

"${ProjDirPath}/Sources/lib_mmcau.a"
