How to enable TTY devices using QUICC Engine UCC UART = Mode?

Are Linux kernel patches enough to enable them? = Or, additional programming required?

The kernel has QE patches, and I am able to use QE = Ethernet. Also, I can choose the QE slow UART mode in kernel configurations. = But, can not see TTY devices from QE.

Thanks,

Ying

Or, additional > programming required? I'm working on a device driver for QE UART mode, but it's not working yet. The QE UART is like the CPM UART, but I'm having troubel getting it to work. It is *not* trivial, or even easy, to enabled. It's a full-blown UART driver that also deals with the complexity of the QE. -- Timur Tabi Linux Kernel Developer @ Freescale From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from airmail.wirelessworld.airvananet.com (airmail.airvananet.com [12.6.244.34]) by ozlabs.org (Postfix) with ESMTP id 179EEDDF1F for ; Tue, 3 Jul 2007 02:02:58 +1000 (EST) MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Subject: RE: Anyone using QE UART mode?

We have 2 working serial ports from the DUART controller, but we need more than 2. We have about 4 weeks to make them working, any suggestion where to start? We plan to start with CW QE Utility generated codes.
