Hi, I am using linux2.4.16 on ks8695 which has ARm922T core I try to setup a memory region to be noncacheable with ioremap_noncache() function. However, it seems to be that memory is still cache, and even though i am using invalidate_dcache_range() to invalidate that region, that region is still cache. Anyone has experience with this chip or the chip has bug in data cache...
Thanks
