Hi,

This question is mostly addressed to Philips stff who does monitoring 
to this group.
We have preliminary samples of our LPC-H2214 board with external 
Flash, SRAM etc. Everything works fine so far when use JTAG 
debugging, but when we try to load code in Flash with Philips ISP it 
programs the internal Flash, then fails in the middle of verify 
operation.
The same situation was with LPC212X microcontrollers with old 
bootloader, and everything fixes when new bootloader is burned in the 
LPC212X.

So is there other bootloader version for LPC2214 which will cure this 
problem?
Dispite ISP tells that verify fails everything is programmed 
correctly inside LPC2214, so I guess this is some stupid timing issue.

The LPC2124 is marked TS0432 A 
the crystal is 14.7456Mhz 
bootloader rev. 1.63

Best regards
Tsvetan

A couple of quick questions,

Which version of the ISP utility are you using?
And do you know where in the verify it fails?

the reason for asking is that there is apparently a problem in comparing 
the first area of the flash.

thanks, this explains it all, after calculating vectors in buffer and 
save hex, compare now works

any idea why this problem doesn't show on the other LPCs but 2214?

Where from?
I've only got 2.1.0!
