Cannot boot up properly

Hi experts,

I’ve just got my brand new GoPiGo kit with several sensors and I completed building the kit but It didn’t work. Literally, it doesn’t do anything… From the Raspberry kit itself, I can see red led is always on and green led is blinking 4 times ( Actually 4 fast blink and 4 slow blink ). Even after I connect the ethernet cable, there’s no led blinking at all. I suspect some SD issues but I also bought this 8GB SD card from the Dexter. How come it doesn’t work ? What should I do in this situation? Should I buy another larger SD card then??
It would be highly appreciated if you can give me any advice.


I’m really sorry that you’re experiencing such a disappointing start. It does sound like the SD card is corrupted for some unknown reason.
You can choose to re-image the card yourself by following the instructions here or request another SD card. Re-imaging the card yourself is the fastest solution.


Thanks Cleo for the comment. Now I’m trying to do re-imaging on my sd card but I can see some existing files like *.dtb and .elf / etc. in it. Should I remove them all first and do re-image ? Or just let them in and move forward ?

Re imaging the card by using Etcher or win32diskimager will overwrite everything . You don’t need to clean up. If only kitchens were like that. Cleo

Many Thanks! but I encountered another problem with wifi setting. When I use WPA gui to configure my wifi network, I can see several possible wifi networks but I cannot actually connect to them. I attached the screen shot showing only “scanning” as status. Can you please give me any advice on this?
