Other Parts Discussed in Thread: AM3352

Hello,

i have followed the link http://processors.wiki.ti.com/index.php/AM335X_DCAN_Driver_Guide to install CAN on my custom AM3352 board.

i made can utilities and copy the files on my target file system :

/bin/ : candump canecho cansend cansequence

/bin/ : ip.route2

/etc/iproute2 : files already here

/sbin/ ctstat ifcfg nstat routel rtmon rtstat tc genl ifstat lnstat routef rtacct rtpr ss

/lib/ : libsocketcan.a libsocketcan.so libsocketcan.so.2.2.0 tc libsocketcan.la libsocketcan.so.2 pkgconfig

With ifconfig i only have "eth0" and "lo" displayed.

Must a CAN controller be really present on my board to have can0 interface in linux with ifconfig ?

Thanks

Regards

Did you do

ifconfig -a

ifconfig alone only shows interfaces that are up. Adding the -a shows all interfaces.

Hello,

thanks, even with ifconfig -a i have no can interface.

Should a CAN peripheral be physically present on my board to have it declared with "config -a" command ?

regards
