I have an LPC4350 based board that came in for repair.  I have discovered that you cannot read/write internal AHB SRAM address 0x20004000 to 0x20007FFF.  The processor issues a hard fault when code tries to access this memory area.  Using the IAR IDE memory window, you only see "--" in this memory range.  Other memory ranges seem to work fine.  Any ideas on what may be wrong?  Just a failed part???
