STM32C0 Boot Programming

[KGane.1]

Hi, I am planning to use STM32C011F6 for a simple application and want to download application through UART1. How to use BOOT0 pin to program MCU for the first time.

According to data sheet, UART1 pins PA9/PA10 needs remapping to function as UART. Also the default functionality of PA14-BOOT0 is SWD interface SWCLK.

How to program MCU for the first time without using SWD interface?

The latest (Rev 57) AN2606 Application note "STM32 microcontroller system memory boot mode" has a C0 chapter stating

"Note:On WLCSP12, SO8N, TSSOP20 and UFQFN20 packages USART1 PA9/PA10 IOs are remapped on PA11/PA12."

Haven't tried it, though.
