flashing internal memory for STM32F730 by UART1

[AKuhn.2]

I am flashing the internal memory for STM32F1xx by UART1 by setting: boot0 to high and boot1 to low; then booting from internal flash: boot0 to low and boot1 to low; all OK;

I want to flash (UART1) and boot (internal) in the same way with a with a STM32F730R8T6.

But there is no boot1 pin. How to set boot0 pin or what else to to?

If you don't meddle with the Option settings, you should just be able to pull the BOOT pin high or low to run from ROM or FLASH respectively, via the default BOOT_ADD0/1 settings
