PCB not working with Raspberry Pi2

[pbonguardo]

Hello,

• I made the PCB based on the Gerber files provided and connected the board to the Raspberry Pi 2 (noting that the GPIO layout is different: 26 pins for the Raspberry Pi 1 instead of 40 pins for the Raspberry Pi 2). see pictures enclosed.
• I configured the Raspberry Pi 2 as explained on the web page "Setting up the Raspberry PI to act as Central Station 2" https://www.ifoedit.com/RaspiCS2SoftEn.html.
• Unfortunately, it looks like the PCB is not recognized. When trying to execute the command "sudo ip link set can0 up type can bitrate 250000" this returns an error message "Can't find CAN0 device".
  my questions are:
• did the PCB board already worked successfully ?
• can you please confirm the values of the resistances ?
  R1: 4,7 kOhm
  R2 and R3 18 kOhm. (the value of R2 is not indicated on the schematic pican.pdf)
  Thank you.
