WICED Studio Wi-Fi Combo

New Contributor II

Hello,

I'm following the Sterling-EWB Development Kit - Software guide. https://connectivity-staging.s3.us-east-2.amazonaws.com/2019-07/CS-GUIDE-EWB_DevBd-SW%20v1_0_0.pdf

I tried to build the section 5 Sterling-EWB Sensor Demo but getting the following errors. So does the libalgobsec.a need to be built with softfp?

Solution:

CS-GUIDE-EWB_DevBd-SW v1_0_0.pdf, Section 5.2 Building and Downloading the Demo Step 3 is incorrect:

Source: https://github.com/LairdCP/ewb_wiced_demo/issues/2

The .a file libalgobsec.a needs to be built with softfp! The Cortex_M4F uses the hardfp.

Wrong statement.

  1. 3. Copy the two .h files and one .a file from

...\algo\bin\Normal_version\gcc\Cortex_M4F

Corrected:

  1. 3. Copy the two .h files and one .a file from

...\algo\normal_version\bin\gcc\Cortex_M4

Also get the error: Undefined 'WPRINT_BT_APP_INFO'

Solution:

Add the following lines in the apps\laird\demo\ble\profiles\wifi_config_profile.h

/* Bluetooth application tracing macro */

#ifndef WPRINT_BT_APP_INFO

extern wiced_mutex_t global_trace_mutex;

#define WPRINT_BT_APP_INFO(info)    { \

wiced_rtos_lock_mutex(&global_trace_mutex);     \

WPRINT_APP_INFO(info); \

wiced_rtos_unlock_mutex(&global_trace_mutex);   \

}

#endif

I'm not particularly familiar with the LAIRD specific examples. But from the error log, I can confirm that yes, libalgobsec.a need to be built with softfp.

The pre-built libraries of WICED comes only in a softfp option. Hence, mixing softfp with a hardfp compiled library is not link compatible.

Thank you! Yes, libalgobsec.a needs to be built with softfp, which led me to the solution above.
