Re: [Bacnet-developers] Having problem porting STM32F4xx

[Emre C. K. <krt...@gm...>]

Hello Steve,

I tried the IAR Workspace file and it is compiled and now seems to be
working. But when the program is running, MCU resets itself repeatedly. As
far as I know, the watchdog timer is not enabled. Do you have any idea what
may cause this?

Best regards,
Emre
