Does MQX use the hardware watchdog

[barbercolman]

Hi

I am using MQX 3.7 and CW10.1 I have a project based on the gpio demo for the MFC51JM eval board. I am new to Freescale and MQX, but learning. As far as I can tell MQX has its own software watchdog but does not set or use the hardware watchdog. Is this correct? If it is correct any quide lines on using the watchdog? Does the BDSM debugger stop the hardware watchdog?

Any help or suggestions?

Thanks

Hi Barber,

The FSLMQX3.7 doesn't yet support the JM128 on-chip watchdog but it is supported in the MCF52259 code.  I have tested it long ago but not recently as fyi.

If you look at the init_bsp.c file in the FSLMQX3.7/mqx/source/bsp/m52259evb _bsp_timer_isr() .

Hope this helps.

Regards,

David
