I'm writing a module for dm6446.
I need to write to address 0x4000000, which is
DAVINCI_ASYNC_EMIF_DATA_CE1_BASE . I tried several options but they
always fail.
I tried:
outb (data, 0x4000000);
davinci_write (data, 0x4000000);
__raw_writeb(data, 0x4000000);
I always get the error "unable to handle kernel paging request at
virtual address 01000000".
Do you have any hint about accessing emif? I suspect this is not the
way I should use emif...
Thanks.
