Let's Get Started - Garbage Serial Terminal Output
Hi,
I've been following the guide over at:
I'm using a Windows 10 as a host, but I was hoping I'm not the only one. I don't have access to a Linux environment at the moment.
I'm at the point where I need to connect to the device using the UART/ST-Link, power on, and press reset on the device to see an output on the terminal.
My setup is:
- Host is Windows 10
- Terminal is called Termite 3.4 (no install version)
- DK2 is powered from a dedicated USB power (500mA source)
- DK2 boots up fine (the display works and the demo environment seems to work ok)
- Serial settings I have as follows: COM3 9600 bps, 8N1, No Handshake
- 8 bits, no parity, 1 stop bit, no flow control
The output in the terminal, after pressing reset, is all jumbled and garbage:
