Subject: c2port (Version 3): support for Silicon C2 Interface.
Date: Wed, 22 Oct 2008 22:53:19 +0200 [thread overview]
Message-ID: <1224708801-16675-1-git-send-email-giometti@linux.it> (raw)
In-Reply-To: <>
C2 port implements a two wire serial communication protocol (bit
banging) designed to enable in-system programming, debugging, and
boundary-scan testing on low pin-count Silicon Labs devices.
Main references are at Silicon Laboratories site:
* AN127: FLASH Programming via the C2 Interface
http://www.silabs.com/public/documents/tpub_doc/anote/Microcontrollers/Small_Form_Factor/en/an127.pdf
* C2 Specification
http://www.silabs.com/public/documents/tpub_doc/spec/Microcontrollers/en/C2spec.pdf
Currently this code supports only flash programming through sysfs
interface but extensions shoud be easy to add.
Changelog
=========
Version 2 -> 3:
---------------
* Static variables fix up.
* Update_lock is now initialised at compile-time, not at runtime.
* Memory leak in c2port_device_register fixed.
* Comments review.
Version 1 -> 2:
---------------
* Documentation added.
* One client added.
