Hi. Recently I started a new personal project, where I'm trying to develop my own SMD-to-female-header PCB for the STM32F207VCT6 MCU chip. After ordering all the parts, doing some reflow soldering, checking that there are no solder bridges, and verifying that each pin properly reaches its corresponding header, I proceeded to connect the following circuit to it. Most of it comes from the AN3320 application note for this chip.
In order to program it, I got an FTDI FT232R board and connected it to the chip's USART1 (PA9 and PA10). Additionally, I set pins Boot0 and Boot1 to HIGH and LOW respectively to boot from system memory. From what I've seen from other blogs, a connection between STM32 chips and the STM32CubeProgrammer software can be done via USART. However, I'm getting the following error.
I tried setting the Baudrate and parity settings to every combination available, I tried resetting the chip multiple times, checked the appropriate voltages for VCC and VCap, and tried other USART ports on the chip. Am I doing something wrong?
