I found myself in a conversation about ESP32 boot times. Specifically the time it takes from boot until user code can do something useful with an IO.
As this was something relevant to Richmote but I didn’t have any actual data I decided to
do a simple setup to measure the results. My test setup consisted of two probes one connected
to the RST line and the other to a random GPIO. The firmware would immediately setup the
GPIO as an output and pull it HIGH. Nothing else.
