DRA7xx - question on cache_wb

John H. Gardner

Does cache_wb only write the specified bytes, or is this (like address) quantized on cache line size? If address is not cache line size aligned where does write back start?

Hello John,

The cache write back gets aligned on the cache line size. If address is not aligned with cache line size the write back happens at the start of cache line where address belongs.
