Lpc2000

Hello,

A read-only version of my boot sector diagnostics for LPC family (Windows 
executable) is available at:

   http://www.cse.unsw.edu.au/~jayas/esdk/files/lpc/bsdc.exe

If you wanted to find out information about the LPC variant as stored in 
the boot sector (that may be different to what is on labelled on the 
outside), connect your serial (or USB VCP) port, reset it with jumper so it 
enters ISP mode, and run this utility to obtain information as follows:

What it does is to use ISP "W" command to write a 360-byte program to 
on-chip ram at 0x40000200.  This program determines the start address of 
the boot sector for the particular variant, and then dumps the contents in 
hex format.

You can use this to make a copy of the boot sector Intel-hex format by 
invoking it with optional file name argument as:

>[temp] bsdc -l com8 save.hex

The file "save.hex" will contain full dump of the boot sector.

The default baud rate is 9600 (so it works with any crystal you may have) 
but if you know your board will work at higher baud rates, then you specify 
this using the ":" delimiter for the serial port argument.  For example, 
you could use "com8:230400 instead of "com8".

If it does not do the right thing for your part, or if any of the 
information  displayed appears incorrect, please email me about it.
