Apologies for confusion. The second RPi I bought originated from Dexter Industries. But it was messed up by my mistake. So management kindly sent me a new SD card via the Amazon store.
This card I had to update according to help from a Dexter Ind. administrator, all info on the Dexter website FORUM pages, I believe. At this point I have still not been able to get the RPi (BrickPi) to respond to … anything. The lights on the Pi all do flash, which I take as a good sign.
Hmmm, the BrickPi does not move… maybe I need to program it first ?
But that does not explain why I can Not get the RPi to answer my many PING attempts.
The mechanical aspects of the new RPi SD card socket and the new card don’t seem right. I have to push hard to get the card seated in the socket. The other RPi that I bought from a different source ( Not Dexter Industries ) works smoothly when placed and removed from the socket.
The behavior of the Dexter bought card does not seem right. There appear to be two or more labels pasted on the card; it seems a little bulkier.
PS. No, my first RPi purchase was from another vendor, NOT Dexter Industries. It works fine.
Both the Dexter-bought SD card and RPi SD Card socket do not seem to have been produced correctly.
