Title: A20Micro very slow work with USB-SERIAL-CABLE-F
Post by: ROM on January 18, 2016, 10:10:09 AM
Hello!

I plugged the card through a USB-SERIAL-CABLE-F and minicom. After loading is not responding to keystrokes.  After some time, it can lead to the console everything that I typed earlier. In very rare cases, it works well.

Connection settings: 115200 8N1.

Tell me, please, why can this be?
