Unable to init QSPI

I am trying to initialize QSPI module on MCF52259. But reading and writing MCF_QSPI_QMR register causes an access error.




I looked into the exception frame. It gives me "Error on operand read" when reading the register and "Error on operand write" while writing the register.


I do not know what causes the problem.


I even initialized the Port QS but still no luck.


Here is exception stack frame for both read and write


Read: - 0x4C082704

Write: - 0x48082708


Also, the error is not just related to one register. It causes problem with all QSPI registers.


Any help will be highly appreciated.
