you may also use the iord/iowr_32direct functions

I use these 2 functions but i can just write to memory with IOWR_32DIRECT() and i cant read data with IORD_32DIRECT()

What do you mean you can&#39;t read?

If you&#39;re not seeing the read strobes on the chip, you might be accessing a cached value. Set bit 31 in the read address to bypass the cache.
