I am trying to load my code using USART in STM32F730Z8T6 via st-link v2 usbdriver(Bootloader provided by ST). I am getting "No response from device" error message. How do I fix this?

The hardware pin has been set high and the boot address in register is same as ST programmed value. Baud rate is set to 9600.

Does it function otherwise?

What board?

Is it using a supported USART and pins?

Is bootloader triggered by configuring the BOOT0 pin which level is latched at reset rising edge?

Maybe do this manually, then use the USART?

Yes the board functions otherwise. We have designed our own board. PA9 and PA10 have been used for USART and they are supported.
