SYMPTOMS
On a Windows Embedded CE 6.0-based device, you cannot access the physical memory address if the value of the address is larger than 0x1FFFFFFF. For example, when you try to access the address 0xFFF80000, you may access the address 1FF80000 instead.



CAUSE
This problem occurs because of a coding error in the kernel. This coding error causes the highest three bits of the address to be lost.
