/****************************************************************************** Project: Portable command line ISP for Philips LPC2000 family and Analog Devices ADUC70xx Filename: lpc21isp.c Compiler: Microsoft VC 6/7, GCC Cygwin, GCC Linux Autor: Martin Maurer (Martin.Maurer@clibb.de) Copyright: (c) Martin Maurer 2003-2005, All rights reserved Portions Copyright (c) by Aeolus Development 2004 http://www.aeolusdevelopment.com Version: 1.29 Change-History: 1.00 2004-01-08 Initial Version, tested for MSVC6/7 and GCC under Cygwin 1.01 2004-01-10 Porting to Linux (at least compiling must work) 1.02 2004-01-10 Implemented conversion intel hex format -> binary 1.03 2004-01-25 Preparation to upload to public website 1.04 2004-02-12 Merged in bugfixes by Soeren Gust 1.05 2004-03-14 Implement printing of error codes as text / strings 1.06 2004-03-09 Merged in bugfixes by Charles Manning: The '?' sychronisation does not reliably respond to the first '?'. I added some retries. The LPC2106 sometimes responds to the '?' by echoing them back. This sometimes causes an attempt to match "?Synchonized". Added code to strip off any leading '?'s. Timeouts were too long. Change from RTS/CTS to no flow control. Done because many/most people will use only 3-wire comms. Added some progress tracing. 1.07 2004-03-14 Implement handling of control lines for easier booting 1.08 2004-04-01 Bugfix for upload problem 1.09 2004-04-03 Redesign of upload routine Now always 180 byte blocks are uploaded, to prevent small junks in uuencoding 1.10 2004-04-03 Clear buffers before sending commands to LPC21xx, this prevents synchronizing errors when previously loaded program does a lot of output, so FIFO of PC runs full 1.11 2004-04-03 Small optimization for controlling reset line otherwise termonly starts LPC twice, free PC buffers 1.12 2004-04-04 Add switch to enable logging terminal output to lpc21isp.log 1.13 2004-05-19 Merged in improvement by Charles Manning: Instead of exiting the wrong hex file size is corrected 1.14 2004-07-07 Merged in improvement by Alex Holden: Remove little/big endian dependancy 1.15 2004-09-27 Temporary improvement by Cyril Holweck: Removed test (data echoed = data transmited) on the main data transfert, since this was the biggest failure reason and is covered by checksome anyway. Added COMPILE_FOR_LPC21, to have target dump it's own memory to stdout. 1.16 2004-10-09 Merged in bugfix / improvement by Sinelnikov Evgeny I found out that Linux and Windows serial port initialization are different with pinouts states. My board don't get reset signal at first cycle of DTR pinout moving. And I add this moving to initalization cycle. 1.17 2004-10-21 Changes by Cyril Holweck Divide main, take out the real programming function, that can also be used by a target to copy its own code to another. 1.18 2004-10-26 Changes by Cyril Holweck Added a "G 0 A\r\n" at end of programming to run code. 1.19 2004-11-03 Changes by Robert Adsett Add support for Analog Devices. Separate file load from programming. Change from a debug on/off flag to debug level Remove if(debug) tests and replace with DebugPrintf statements. Change serial I/O and timing so that the system dependancies are isolated to a few portability functions. Add support for binary serial I/O. Add doxygen support. 1.20 2004-11-07 Preparation for multiport booting (factory support) 1.21 2004-11-08 Bugfix from Robert Adsett BinaryLength was not initialized 1.22 2004-11-08 Changes from Cyril Holweck / Evgeny Sinelnikov Forgotten IspEnvironment-> and bugfixes if COMPILE_FOR_LINUX If COMPILE_FOR_LPC21, PhilipsDownload() 'acts as' main(): - it should not be static and should return int. - no sub-function can use exit() but only return() Use 'char' instead of 'byte' ;) 1.23 2005-01-16 Build in automatic detection of LPC chiptype (needed for 256 KByte support) 1.24B 2005-06-02 Changes by Thiadmer Riemersma: completed support for other chip types (LPC213x series and others). 1.24C 2005-06-11 Changes by Thiadmer Riemersma: added the device ID codes for chip types LPC2131 and LPC2132. 1.25 2005-06-19 Martin Maurer: Setup more parameters in DCB, otherwise wrong code is downloaded (only Windows and Cygwin) when a previous program has changed these parameters Check exact string of "G 0 A\r\n0\r\n" instead of whole received buffer, to prevent checking of already received by program start (error on running program, but reports CMD_SUCCESS) Add ifdefs for all baudrates (needed only for high baudrate, which seem to be not available on Macs...) 1.26 2005-06-26 Martin Maurer: Correct check again: "G 0 A\r\n0\r\n" is cutted, because of reboot (error on running program, but reports CMD_SUCCESS) 1.27 2005-06-29 Martin Maurer: Add LPC chip ID's (thanks to Robert from Philips) for missing LPC213x and upcoming new LPC214x chips (currently untested, because i don't have access to these chips, please give me feedback !) 1.28 2005-07-27 Anders Rosvall / Embedded Artists AB: Changed the reset timeout to 500 ms when entering the bootloader. Some external reset controllers have quite long timeout periods, so extening the timeout delay would be a good thing. 1.29 2005-09-14 Rob Jansen: Added functionality to download to RAM and run from there. In LoadFile() added record types 04 (Extended Linear Address Record) and 05 (Start Linear Address Record), added address offset (IspEnvironment->BinaryOffset) and start address (...->StartAddress). Changed PhilipsDownload to skip all Flash prepare/erase/copy commands.
