ESP32 startup times
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.
