STM32F103 LD3 light is always red when USB is connected
I'm trying to build a simple hello world program with STM32F103 board using SWD debugger and ITM feature. But when I plug my USB cable on my PC, I have my LD1 and LD3 always in red light. Is that a problem? If so, how to solve?

Resolved! USBPD_PE_SetDataInfo Function was not executed,why?
stm32G071 UCPD SINK code answers GOODCRC after received SRC_CAPABILITY,but USBPD_PE_SetDataInfo Funtion was not Execute after GOODCRC,why?
Resolved! I am currently working with an STM32F051K8U6. According to the docs from STMicroelectronics AN2606, page 303, this chip supports bootloading on both USART1 (PA10, PA9) and USART2 (PA3, PA2). I can get the bootloader to work fine on USART1 but not USART2
I can get the bootloader to work fine on USART1 but can't seem to get anything from USART2. Is there a trick to making the second USART port work? I have checked the output from my test serial port on the logic analyzer and it seems correct and is s...
