MPC8309 UCC-HDLC driver of Linux

[lijiankun198]

Hello everyone, I have learned MPC8309 just for a week. In my project I need to set the UCC7 to HDLC mode. But I just find the driver of UCC-rs485 instead of HDLC in bsp kernel.   Can anyone provide the driver of UCC-HDLC or some advises?  Thanks!!!

Have a great day,

Unfortunately there were several requests for the driver of UCC-HDLC but in vain. See for example

https://community.freescale.com/message/387298#387298

So Linux does not include a full-feature HDLC driver for UCC hardware. May be the next can help you

Freescale provides UCC HDLC driver for Netcomm software (it is OS agnostic) and tdm Linux driver in the MPC8309-KIT BSP. Please see details in https://community.freescale.com/message/409264#409264

Recommended Device tree elements for a UCC are specified in the kernel source
