I'm trying to download the log files using either QGC or MAVSDK but nothing happens when I request the files. This is with a Pixhawk 4 and Pixracer.

This seems to be a MAVLink specification problem. If there are no logs on the SD card then there is no response to LOG_REQUEST_LIST which looks the same as a timeout.

I'm closing this since it's not a PX4 problem as such.

I found that actually PX4 sends one LOG_ENTRY with id = 0 and num_logs = 0 to signal that there is no log available.
I will add that to the specification: mavlink/mavlink#1363
