Can I protect certain areas of memory from being overwritten when loading through the USB Tap?

We are working with the 56800e 56f8367 chip.

We set up a section of memory in the linker file where we load code for an FPGA. This is loaded through a SCI port.

In the Classic IDE I was using the Local Hardware Connection to load the chip and this area of the code was left untouched. However, if I load with the USB Tap, this area of memory gets wiped out.

We have moved to new computers which do not have parallel ports, so I am required to use the USB Tap. Why there is this difference and if there is anyway to avoid wiping out this memory when using the USB Tap?

Thanks

Charlie

Found a solution.

In the MC56F8367.mem file, it gives the ability to define areas of memory as either readwrite or just read (maybe other things, I didn't really check). I made those memory addresses read only.

Then when I went to download code, it would throw an error. I assume it was doing this because it was trying to erase those memory locations and it was blocking itself. I basically told it to ignore the error in the future and everything is running fine.
