Is there a possibility to erase the whole flash memory in LPC2xxx chip
using the IAR J-LINK programmer/debugger with IAR EWARM?

It is not difficult to erase the entire flash by downloading code
(that does not depend on code in boot sector) into RAM and running it
from there.
However, according to Philip, if bootloader corrupted this may prevent
the JTAG communications from working.
You most likely end up with with a dead part unless you have a
parallel programmer that supports your LPC part to reload the boot
sector from scratch.
