DSP6713 connect to SDRAM 256Mbit

Pere Carcel Garcia

In the first contact with this DSP I made different test with the evaluation board DSK6713 and everything was fine. Right now, I've a board desing with a small differences respect to the evaluation board. One of the diference is the sdram memory that i put 256Mbit, 4 blocs, 12 row, 9 col with 32 datas. In one of the datasheets says that this memory is possible to manageted bud when i make the test doesn't work, just work if only make test until 0x10000 address. Some have the solution...

The schematics is identically to the memory of the DSK.

I apreciate your time. thank you in advance

Hello Pere,

Would you mind giving more information on your configuration of the SDRAM control register (SDCTL)?

SDCTL register configuration, pg 90, TMS320C6000 EMIF Reference Guide

A schematic of your DSP to SDRAM connection may be able to give more information on what could be wrong.

Table 3-3, pg 74 of the TMS320C6000 EMIF Reference Guide has compatible SDRAM and the appropriate pin connections.

Also what SDRAM are you using?
