This seems to be a regression from OpenOCD 0.4.0.

BTW, it seems to me DCC is not enabled by default.

Verification will fail since checksum in image (0xe59ff004) to be
written to flash is different from calculated vector checksum
(0xb9205f88).
To remove this warning modify build tools on developer PC to inject
correct LPC vector checksum.
