if I connect SD Card - LF33 will be very hot in a short time

[Rio]

Hello,

 

is it normal that LF33 will be very hot in a short time when I connect a SD Card to J16? There is only the bootloader installed and after inserting SD Card -> the LCD shines a bit weaker and Core's LED switched of and it restarts after removing SD Card again. With Card inserted the core won't complete boot.

 

The core gets power via external 5V.

 

Thanks for help.

Not normal.

You need to:

• Check the wiring terminations between card and core (are all the connections correct?).
• Check the card in another computer (Does the card work?).
