HDLC drivers on 8260

HDLC drivers on 8260

[Alejandro C]

Hi there,

I've just started developing a driver to use the four SCCs (CPM of the 
Motorola
MPC8260) in the HDLC mode. I've found references to a HDLC driver somewhere 
on the internet, but I haven't been able to locate the source code. Does 
anyone know where to find this or something else I can use as an 
example/starting point?

Thanx,

Alex

I don't know a thing about the SCCs in the MPC8260, but you may want to
have a look at the Cyclades PC300 driver in the kernel. It does HDLC
(but I don't remember whether it's the PC300 driver or a generic HDLC
driver in the kernel). What HDLC do you wnat to implement? There is no
generic HDLC per se, but different framings using a HDLC-like framing.
Examples would be Cisco's IP over HDLC, or PPP.

For Cisco's HDLC, I added IP address autoconfiguration to the PC300
(submitted to the maintainer, but never found it's way into the official
kernels).

Cheers

Michel
