Thanks for your interest in the Intel® Aero™ Platform for UAVs.
I understand what you are trying to explain. Please let us investigate if it is possible to activate the minicom while the Aero is booting.
We appreciate your patience, have a nice day!
Looking at the Aero Compute Board Hardware Guide Intel® Aero Compute Board Hardware Features and Usage Guide , it seems like the HSUART is meant to be used to connect other devices such as an external flight controller. We would encourage you to use the HDMI in order to interact with the Aero Board.
Now, is there any particular reason that you wish to interact with the Board through a UART connection?
Have a nice day!
Thanks for the reply! It's just because I've got only one monitor, which is being used by my desktop and I want to go into BIOS every time it boots coz I want to boot from a USB drive.
It's fine. I guess I'll just get another monitor.
