[ECOS] HAL_DCACHE_FLUSH(addr,size);

[ECOS] HAL_DCACHE_FLUSH(addr,size);

[mkhoyila]

thanks Gary

I have another question with regard to: HAL_DCACHE_FLUSH(addr,size);

I used the above function to invalidate and write back my cache, But it is
not working. Is there any other function in eCos to do that. Thanks.


static inline void cache_wback_inv(unsigned long addr, unsigned long size)
{

        HAL_DCACHE_FLUSH(addr,size);   /* Hit_Writeback_Inv_D */

}

What target are you using and what version of eCos?

My target is MIPS board and I am using eCos 2.0
THX

The MIPS cache macros are broken in eCos 2.0. Upgrade to something not
so ancient.
