STM32WBA52 Zigbee_OnOff_Client_SED Hard fault for ZB_LOG_MASK_LEVEL_3 or higher

[SToma]

Hello,

during testing Zigbee_OnOff_Client_SED example, hard fault in time of joining network happen, when logging with ZB_LOG_MASK_LEVEL_3 or higher is configured. With ZB_LOG_MASK_LEVEL_2 or lower example works fine.

Hard fault analyzer report PRECISERR with BFAR 0x280027. Origin seems to be in the ZbLogPrintf (see attached screenshot with stack). Because it's library, it's out of my range.

Depth, lqi, pjoin values are reported weird. See next log.

Any suggestion, except keeping log mask level low?

Thanks, Slavomir Tomascik

Hello @SToma,

Thanks for your post.

Indeed, when the trace level of Zigbee stack is set to ZIGBEE_CONFIG_LOG_LEVEL_3 or higher, some data printed are of type uint64_t and are not supported by the compiler configured to use the Reduced C library by default, leading to a HardFault.

In order to use a high trace level, please change the default parameter of the project following this directory :

MCU Settings/ Runtime library -> Standard C instead of Reduced C

Best regards,

Ouadi

Hi Ouadi,

thank you. Standard C library solve hard fault problem.

Rssi and lqi values are still off, but it's working.
