Lpc2000

I'm programming an lcp2106 with the IAR tools and J-Link, and program was
dieing.  As a check I turned on JLink's ability to verify a flash download
by reading it back and comparing.

The verification fails with a series of errors like this:

Target inconsistency detected at memory address 0x000000F9
Target inconsistency detected at memory address 0x00000024
Target inconsistency detected at memory address 0x00000028
Target inconsistency detected at memory address 0x000000FC
Target inconsistency detected at memory address 0x00000101
Target inconsistency detected at memory address 0x00000104
Target inconsistency detected at memory address 0x0000012C
Target inconsistency detected at memory address 0x00000110
Target inconsistency detected at memory address 0x00000020
Target inconsistency detected at memory address 0x00000070
Target inconsistency detected at memory address 0x000000A8
Target inconsistency detected at memory address 0x000000D4
Target inconsistency detected at memory address 0x00000121

These are always in the same place in memory.  I lowered the JTAG speed to
minimum, and this did not help, and the errors stayed exactly the same.  I
also switched between ARM the THUMB mode and they stayed the same.

It's a new chip, and other big programs that I've downloaded with Philips
downloader run fine.  I don't have another chip handy to do a comparison.

Is this likely to be faulty flash memory?  How often does this happen in new
chips?  Could it be a power supply problem?  (although the voltages seem
correct)

Thanks for any advice you can offer.
