[ECOS] Ethernet on 5912

[ECOS] Ethernet on 5912

[mac]

hi,
I want to enable Ethernet on omap 5912 osk, and its base address is 0x0480 
0000.
There are 4 memory banks cs0, cs1, cs2, and cs3 (EMIFS_CS0 ~ CS3 ) on 5912.
The problem is that I can only  access cs0 and cs3, but 0x0480 0000 is in 
cs1.
Do I need to set some config registers to access cs1?

Thanks for your help.

Best Regards

K-C Lee

Thanks, after adding this into hal_mmu_init(), I can use Net-function on 
5912.

Thanks for your help!

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.
