On the lower screen segment you fnd status reports. The CPU use is
displayed as a bar on the upper right.

Bootloader/Firmware update:

In order to update the frmware a boot loader is installed in the
DV4mini:
First you save the new frmware fle on your computer. Normally you
will fnd it at http://dv4m.ham-dmr.ch
In the Expert Tab click on "Flash Firmware". This makes the LEDs on
the stick blink in color and then the red one will stay on. A fle
selection window opens and you navigate to the location of the new
frmware fle. After selecting it the frmware will be updated. Now end
the program and restart it again. It may take a little while until the
stick is found again. Be patient.
Generally nothing bad should happen because if any error occurs the
boot loader will be protected. Even with a power outage or
interruption of the USB interface one can just repeat the update.
