i am trying to programm stm32f429 MCU on custom board with keil,

i have generated project with cubeMx but when trying to programm the MCU i get the message 'Flash Timout. reset Target and try again'.

keil can see the MCU but would't erase the MCU.

What could cause that Issue?

Thanks.

Hi

Try to upgrade the ST-Link firmware

and try again.

Please keep me informed about your updates.

Hi,

Thanks for your suggestion,

I have fixed the problem by connecting the VDDA to the VDD ,i was using second regulator which provide

power to the analog part.
