Hi,
 
I am under arm9 with eLinux OS, the UART part has a specific IrDA mode.
 
I've modified the uart driver which can send and receive raw data in all baudrate in irda mode. However where I try the irattach, I found that it just keep on sending the xid out, it seemed that the negotiation fails.
 
But I found that my eLinuxOS does not have ircomm0 device node, does it cause it fails in negotiation?
 
Regards,
