TCPnet crashes my system (Prefetch Abort)

Hi,

I'm working on a project using an LPC2388 with RTX and using the TCPnet stack for communication with a windows tablet. I recently added a bootloader which resulted in the main application being shifted in FLASH to 0x2000.

Currently I'm seeing a Prefect Abort error about 4 seconds after the program starts. R14 points to address 0x642D625C which I seems wrong since it's in reserved address space. I know it has something to with shifting the main application in memory, because I don't see an error when shifting it back to 0x0.

The error only happens before I establish a TCP connection and the really strange thing is that it only happens with certain machines. I run the device on one machine and it will crash but I connect to another computer with the same device and firmware and it runs fine. Only thing I can think that is different is the ethernet traffic over the link. could it be that TCPnet can't handle certain packets? Does TCPnet need to have a different configuration when shifted in memory? Does the PHY driver need to be shifted in memory too?

Very strange error...
