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.

    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.
