Hi,



I have a problem with the CAN-BUS Shield V2.0 extension,

when I add a second card, it doesn’t detect my first one.

I’m testing a two card project from the SDFat library.



error: cardBegin failed

SD errorCode: 0X20,0XFF



Card error on CAN shield,

What could be the reason for the problems?

Arduino Mega

CS PIN CAN - 9 (default)

CS PIN SD1 - 4 (default)

CS PIN SD2 = 53

For hardware,Select anyone ，Cut the wire between pad4 and the middle pad. and Weld the middle pad and pad 5.
