Sometimes on powering Dexter up, the RED LED (right side, facing the MicroZed control board) will stay steady, and not blink. The RJ-45 connector housing LED's may blink if there is a CAT5 cable plugged in. The robot will not boot-dance, and no method of connecting to the robot works, even if it did before.
This is typically caused by a bad or missing or not fully inserted sd card.
It is very easy to not have the sdcard fully or correctly inserted. Especially after connecting to Dexter via the USB Micro A connector because the edge of the USB cable can easily press the sd card up and unseat it.
One can also have a card that is not all the way up into the slot; the card has to be pressed up until a slight click is heard, and then it can not be pulled back out. If a downward tug on the card removes it, then it wasn't in correctly.
If the card is inserted securely, it may be that the data on it is corrupt or it may be empty. See: https://github.com/HaddingtonDynamics/Dexter/wiki/SD-Card-Image for how to burn a good image onto an SD card.
