Hello,

I have a Talon CAN bus IoT board working on an FX30 3G (WP85xx).  
Now I’m trying to migrate the system to an FX30 LTE (WP7702), but I’m having issues bringing the interface up.  
I compiled the system with the Kernel Modules specified for this chip and I got it loaded, but I cannot find the correct GPIO that brings the board up.

> root@swi-mdm9x28-wp:~# lsmod  
> Tainted: G  
> mcp251x 9636 0 - Live 0xbf004000 (O)  
> can\_iot 1072 0 - Live 0xbf000000 (O)

> [14.658633] can\_iot\_init: mcp2515 (gpio:79 irq:131).  
> [14.731595] spi1.0 supply vdd not found, using dummy regulator  
> [14.731692] spi1.0 supply xceiver not found, using dummy regulator

I tried to set the same GPIOs that I have before for the WP85xx (33 and 6), but the system shows me:

> root@swi-mdm9x28-wp:~# ip link set can0 type can bitrate 500000 triple-sampling on  
> Cannot find device “can0”

Is there anyone that could help me with that?

Thank you very much!
