This is good. I managed to upload Blink to my Nucleo L476RG and it was running . However i got garbage on my Serial Monitor when i run another program. The baud rate was correct. Any idea why this happened? Thanks
Hi, it is always hard to give an opinion on what could have gone wrong in varius scenarios. it will only be a guess. Best is to try to eliminate all sources of potential errors and eliminate all till you only securely can reproduce the issue. When their is garbage my experience is that the baudrate is not correct and timing is off. put an logic analyser or Oscilloscop on the bus to verify that this is not the case also here. / PR TechTalk
Quick question for you, is it necessary to use USB to power/program our dev board with the arduino IDE? My project requires our own custom development board with an STM32F103 MCU and I'm wondering if we need to include a female Micro-USB port. I plan on just using a J-LINK programmer with an SWD interface.

Black pill - Blue Pill - similar method? I saw another video where they use an FTDI board to program the black pill - is this unnecessary? ua-cam.com/video/QCdnO43RBK4/v-deo.html&ab_channel=GaryExplains
Hi, im a it unsure over your question, but to program any ST MCU you need some kind of tool. Could be STLink or similar. FTDI is "only" a USB to Uart converter and could be a part of a programmer.

This is really intersting thank you
Your welcome :-)

Hi, No you can supply your design from your own supply. You need to have gnd and data pins from SWD interface only. /PR TechTalk
where link ?
