You still shouldn't use direct access with MMU enabled. Use the global

CPM

mapping and the I/O access macros.

I understand, but I need to kick on the WDT before "cpm2_immr"
is initialized dur to timing constraints.

Hi Guys,
The Software Service Register (SWSR) is 16-bit wide which Laurent
Pinchart [laurentp@cse-semaphore.com] so nicely pointed out for me.
So it actually works with;
*((volatile unsigned short*)(0xf001000e))=0x556c;
*((volatile unsigned short*)(0xf001000e))=0xaa39;

You still shouldn't use direct access with MMU enabled. Use the global CPM
mapping and the I/O access macros.

out_be16(&cpm2_immr->im_siu_conf.siu_82xx.sc_swsr, 0x556c);
out_be16(&cpm2_immr->im_siu_conf.siu_82xx.sc_swsr, 0xaa39);

Best regards,
