Lpc2000

Has everyone seen the LPC2000 errata at:
 
http://www.semiconductors.philips.com/acrobat/erratasheets/2105.pdf
 
Interestingly, there is a new version of the boot loader (the on-chip code
that resides in LPC2000) which is upgradeable using the Philips ISP utility.
Details and files are here:

It seems that the IAP software (in the boot loader) has some timing issues
resulting in a possible 1 in 10 flash programming failure, particularly when
the PLL is enabled and running > 12MHz. Note: this effects all methods of
flash programming (i.e. via UART using Philips ISP or JTAG using Ashling
PathFinder or other Debuggers) as these all call the IAP routines. 
 
I have personally tried the upgrade and it works smoothly using the Philips
ISP utility; I 'm looking at implementing a PathFinder script for Ashling
users to allow updating via JTAG
