Look in 'hal_mmu_init()' in "hal/osk5912/current/src/osk5912_misc.c. You
will find that we only mapped CS0 and CS3 into the virtual address space.
If you add a line that looks something like:
X_ARM_MMU_SECTION(0x048, 0x048, 32, ARM_UNCACHEABLE, ARM_UNBUFFERABLE,
ARM_ACCESS_PERM_RW_RW);
Then you should be able to access CS1 space.
