Hi Muhammad, I would like to access memory to read data from it for debugging purpose? Kindly can you tell how did you create a cpu port to access memory and read the 256 bytes from a specific address?

Hi everyone, I have created a new cpu port which accesses the main memory and bypassing the caches when reading from memory. When I try to read from the main memory via this port, I sometimes fail to read it and it is read as a 0. This only happens when I try to read a value almost after updating it. i.e. it does not update that value in the main memory. What I think is that the value is still stored in the cache, and the cache has not yet updated that value in the memory. How can I make sure that the cache has also written it to the main memory? i.e. enforce writethrough. If my observation is wrong, would someone correct me as to why this is happening and what I might be doing wrong? Thanks, Aamir
