Zymbit4 no blink

I have done the luks crypt and everything was working ok. Today I power up the Pi and it would not boot as the boot key was not accessible by the Pi. The Zymbit led is not blinking at all. Also, the tab has not been cut yet.

What could be wrong here. Is the Zymbit Key dead?

Hello Albert,

Can you tell me which PI, OS, and capture the last messages you see on the console? Is this a new setup or has it been working fine for a long time and then stopped working after the power up?



It was working for fine for a few days with powering up and down. Then on the last time I powered it up, it would not boot and the Zymbit with no LED blink. The PI itself is working as I have reinstall the OS and Luks Crypt with a new Zymbit.

Putting the Zymbit on a new Pi also did not result in any blinking LED.
