Forum Post: RE: Custom AM3359 Board DDR3 Issues

The behavior is the same with that change to SDRAM_CONFIG.

Am I correct in believing that as I have the EMIF configured, the address as viewed in CC Studio or in the software should will be translated as follows:

row address | bank address | column address

So if I were to write to byte address 0x80000008 in CC Studio, it would write to row 0, bank 0, column 4 (since it gets translated from a byte address to a word address).  Correct?

I have been looking at transactions on a logic analyzer.  It appears the memory controller is sending the row address and bank address correctly to the DDR chip.  However, changing bits 1 through 3 of the byte address in CC Studio (which correspond to bits 0 through 2 of the word address) does not impact the lower 3 bits of the column address.  I can make the 4th bit change of the column address change, but not the 3rd bit.  Any ideas?
