Hi

i have implemented watchdog on f429. i have two applications on flash , one is bootloader and other one is an application program . i have implemented the watchdog on bootloader and also jump function from bootloader to appllication.

My goal is to start the watchdog on bootloader, jump to application proǵram and , top the watchdog once the application gets started and runs properly.

the problem is i cant able to stop the watchdog when the application starts.

could anyone help me or suggest me some idea ?

thank you

Hello,

I think you have the same problem as this [DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/IWDG%20disbale%20steps%20for%20STM32F2xxSTM32F4xx&FolderCTID&currentviews=29]discussion

According to the reference manual:

''Independent watchdog (IWDG): the IWDG is started by writing to its Key register or by hardware option. Once started it cannot be stopped except by a Reset.''

I hope this can help you.
