Re: U3s firware update

 

The basic difference between the two is that the 328P implements the
PicoPower standby modes, allowing longer battery life in situations
where the processor is inactive most of the time. None of the QRP Labs
kits use or need those modes, as the processor is always active when
the radio is turned on.

Hi Al, Carl


I have flashed both my U3S and QCX using this procedure. The only glitch
in the doc is in Step 4e "Select ATmega328 as the MCU" It should be
ATmega328P. I believe Hans has stated this is the chip they usually ship.

Sometimes we use ATmega328, sometimes ATmega328P. It depends only on
availability and price, at the time I am purchasing the chips. They are
equivalent for the purposes of QRP Labs kits. So if you get a message about
the device signature being wrong, just change the chip name selection (or
the name in the command if using a avrdude at the command line), try the
other one.
