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.
Note: Tested with VC7 only
1.30 2005-10-04 Rob Jansen:
- forgot to change the version string in 1.29
- Wrong text in LoadFile corrected (printed text mentions record type 05,
this should be 04
- Changed LoadFile to accept multiple record types 04
- Changed LoadFile to check on memory size, will not load more than x MB
if linear extended address records are used
1.31 2005-11-13 Martin Maurer: Thanks to Frank Gutmann
Updated number of sectors in device table
for LPC2194, LPC2292 and LPC2294
1.32 2005-12-02 Martin Maurer: Corrected missing control of RTS/DTR
in case user selected -termonly and -control
Small correction (typo in debug)
1.33 2006-10-01 Jean-Marc Koller:
Added support for MacOS X (difference on how to set termios baudrate).
1.34 2006-10-01 Cyril Holweck:
Made it compile again for lpc21isp
Added const keyword to constant variables to make it better
code for embeded target. (decrease RAM usage)
Replaced all regular call to printf() by DebugPrintf()
Removed call to scanf() (not much usefull and cost a lot to my target)
1.35 2006-22-01 Cyril Holweck
Added feature for LPC21: will start downloading at Sector 1 and upward,
to finish with Sector 0, the one containing the checksum controling BSL entry
1.36 2006-25-01 Cyril Holweck
PhilipsDownload() will now return a unique error code for each error
1.37 2006-10-03 Jeroen Domburg
Added LPC2103 (and only the 2103, I can't find the IDs for 2101/2102)
Corrected a loop which occured if the program completely fits in sector 0
1.38 2007-01-05 Ray Molenkamp
Added feature for LPC21: Wipe entire device before programming to enable
reflashing of chips with the lpc codeprotection feature enabled.
1.39 2007-01-12 Martin Maurer
Added initial support for new processors LPC23xx and LPC24xx

Correction of chip id of LPC2458
1.41 2007-01-28 Jean-Marc Koller
Modified Terminal() to disable ECHO with termios only once, instead of
modifying and restoring termios in each getch and kbhit call (which caused
a strange echo behaviour in MacOS X).
1.42 2007-01-28 Rob Probin
Added -localecho command to allow local echoing in terminal mode for use
where target does not echo back keystrokes.
1.43 2007-01-29 Martin Maurer
Moved keyboard handling routines to own subroutines,
so they can be used during aborting synchronisation.
Newest cygwin made problems, StringOscillator always contained '\0x0d'
at the end, when calling lpc21isp from batch file
1.44 2007-02-23 Yang Yang
Added feature for LPC21: Verify the data in Flash after every writes
to sector. To detect errors in writing to Flash ROM.
1.45 2007-02-25 Martin Maurer
Replace printf syntax of DumpString by a simple pointer to a string
printf syntax is a nice thing, but it is not working :-(
and therefore makes debugging much more difficult...
Moved VERSION_STR to top of file to avoid possible cosmetical errors
1.46 2007-02-25 Martin Maurer
Again corrected debug output: should solve output of
(FFFFFFB5) instead of (B5)
1.47 2007-02-27 Robert Adsett
Raised timeout on AD send packet function.
1.48 2007-04-20 Martin Maurer

Defined BL error 19 (Code Protected)
1.58 2008-05-10 Herbert Demmel [email protected]
I had the special requirement to integrate the program into my own Windows
software compiled with Borland C++ Builder 5. I had to do some minor changes
for Borland (see defined __BORLANDC__) and modified to code slightly to have
some simple callbacks for screen i/o (see define INTEGRATED_IN_WIN_APP).
Please notet that I don *not* check / modify the part for AnalogDevices !!
Besides that I fixed some minor issues:
added dcb.fOutxCtsFlow = FALSE and dcb.fOutxDsrFlow = FALSE (sometimes required)
Now comparing one character less of answer to "Now launching ... code" command
1.59 2008-07-07 Peter Hayward
Fixed freeze under Windows XP SP2 by removing redundant call to SetCommMask.

Added pre-erasure of sector 0 to invalidate checksum before starting
modification of the other sectors, so that the bootloader restarts
if programming gets aborted while writing on a non-empty part.
1.66 2009-03-26 Vito Marolda
Corrected interpretation of intel hex record 03 which is execution start address
and not data segment address
1.67 2009-04-19 SASANO Takayoshi
Add OpenBSD support
1.68 2009-05-17 Martin Maurer
Merge in changes done by Bruno Quoitin (baudrate problem when __APPLE__ is used)
Remove TABs from source code and replaced them with spaces
1.69 2009-06-18 Martin Maurer
Add support for LPC17xx devices
1.70 2009-06-29 Martin Maurer
Further improvement of LPC17xx support
Workaround for booter (4.1) of LPC17xx, which does not echo all sent characters (0D,0A,...)
ISP command GO seems to be broken:
Sending 'G 196 T(0A)'
Answer(Length=15): 'G 196 T(0A)0(0D)(0A)'
leads to 'prefetch_abort_exception(0D)(0A)1FFF07A5'
No solution known...need your help here...
Manual workaround: Use DTR and RTS toggling to start application (e.g. 2 batch files)
1.71 2009-07-19 Martin Maurer
Added LPC17xx with CPUID starting with 0x26 (not according user manual)
