MQX Kernel Data Windows Shows Floating Point IO as No

rajbatra — Sat, 09 Jan 2016 00:00:50 GMT

I've compiled MQX with floating point support (here's my userconfig.h):

#ifndef __user_config_h__

#define __user_config_h__

/* Define user specific modifications of default configuration*/

#define BSPCFG_HAS_SRAM_POOL 1

#define MQXCFG_ENABLE_FP 1

#define MQX_INCLUDE_FLOATING_POINT_IO 1

/* include platform-specific configuration */

#include "mqx_cnfg.h"

#endif /* __user_config_h__ */

However, when I view the MQX Kernel Data screen, it states Floating Point IO as No.

I'm using KDS 3.0.x (haven't upgraded to 3.1 yet).

Question: Is the Kernel Data screen wrong, or did I compile it incorrectly?

Also, my CPU Type shows as Unknown (0x0000) - I'm on a K64.

Attached is a screen shot. Would be curious what others are seeing here when they've enabled floating point IO.

Thanks!

Hello Raj,

Which MQX version are you using??

Please check the below threads and let me know if this helps

printf() with float values

KDS v3.0.0: Floatting point library

Printing Floating point values to fsl_debug_console FRDM-K64F

Have a great day,
Sol

Hi Sol,

This is KSDK 1.2 (so the MQX that comes with it).

My floating point printing works fine - shows up in console - so those links aren't what I was looking for.

The MQX Kernel Data tab (you can access it via KDS in the Menu MQX...Kernel Data) shows that Floating Point IO is 'No'.

Wondering if it's a bug in the tab or if I didn't do something right.

Thanks,

-Raj
