I have a device with MCF52259 microcontroller. I get a block verification error when trying to program Coldfire MCF52259 with Jlink CF. And the device is not working as expected (it hangs at startup) after programming. The block verification error occurs only in address 0x00013000.

If I trick the Jlink by telling that target device is MCF52256 and using the same binary file, no errors occur and device works as expected.

After programming I have read CPU flash memory using Jlink and checked that block starting from address 0x00013000 is different than in my binary file. And again if I have used MCF52256 target during programming, the block from 0x00013000 is correct.

Here is the Jlink script log which I am using...

What could be a problem?
