assert() behaviour

[randyhermes]

KDS 3.0

SDK 1.2

Using MQX

I'm using assert() to check some parameter ranges.

When it is triggered it drops into a infinite loop and nothing is output on the debug console.

There isn't any source for the actual assert function that I can find, so I can't determine how to get it to print out an error message.

And yes, I'm working with a debug image (DEBUG is defined).

I bet I'm missing some compiler define, but I can't find it documented anywhere.

Can anyone help?

Thanks

Randy

I reopen the thread because I have a question related to that topic.

I'm using the IMXRT1050 board and I saw the assertion failed declaration in assert.h file of the redlib library. Here below the code:

void __assertion_failed(char *_Expr) __attribute__ ((noreturn));

/*
* It is legal to reset NDEBUG and re-include <assert.h> hence the
* fact that this bit gets done every time it is included. This
* implementation follows the Rationale to the C99 standard.
*/

#ifdef NDEBUG
# define assert(ignore) ((void)0)
#else
#define _ASSERT_STR(x) _ASSERT_VAL(x)
#define _ASSERT_VAL(x) #x
#define assert(expr) \
((expr) ? (void)0 : \
__assertion_failed(__FILE__ ":" _ASSERT_STR(__LINE__) " : " #expr))

However there is definition of __assertion_failed function nowhere. Does a developer define it or the SDK provide it if some symbol is defined?

Thank you,

Massimiliano

Hi Randy,

In the file <sdk_dir>\platform\utilities\src\fsl_misc_utilities.c, rename the assert_func() to __assert_func(). This function will connect to assert function of compiler.

Then rebuild ksdk_mqx_lib.

Best regards,
Carlos

I'm seeing the same behavior with MCUXpresso IDE v10.1.1 and FRDM-K64F SDK 2.4.2.  How do I rebuild ksdk_mqx_lib?

Hi Carlos

I have this same issue.....but I only have the fsl_misc_utlities.h header file in my project....no source???

I'm using MQX Standard...selected from PE.

If I navigate to C:\Freescale\KSDK_1.2.0\platform\utilities\src .....I can see the following files \ folders.

virtual_com folder

fsl_debug_console.c

fsl_misc_utilities.c

print_scan,c

print_scan.h

In the project directory in KDS I have....

SDK>platform>utilities>inc>

     fsl_debug_console.h

     fsl_misc_utilities.h

again there is no src folder and no fsl_misc_utilites.c??

Hi jerome,

I dont get the problem. Inside C:\Freescale\KSDK_1.3.0\platform\utilities\src the is fsl_misc_utilities.c

Hi Carlos

Yes, correct I can see this file in the Freescale directory as per my post above. The only difference is I'm using KSDK 1.20?

The problem I have is there is no source folder named ie. SDK>platform>utilities>src  for my project in KDS.

See below....

Yes... you can change it in the SDK location. Not in your project.

Hi Randy,

we have reproduced and reported this behavior to KSDK developers. However they are focused on higher priority tasks and will take a look to this issue in some weeks. Unfortunately there is no work around now for this case. Sorry for the inconvenience.

Best regards,
