Dear: I am using the 5402 to develop my system. I want to boot from the flash,and copy code form flash to external sram,but i could not solve a problem. If we boot system from flash,then we should use the /ds pin to selcet the flash because the code was boot from the external data space,but if i map the flash into 4000-bfff(32k), and the sram also map into 4000-bfff,then i will acess the both flsh,sram at the same time. (/ds is active at the same time). If anyone can tell me how can i select the sram ,flash .It will have no confict when I access the external data space! i connected the sram like this,if any wrong,please tell me ,thank you! dsp sram /mstrb /ce r//w /we Gnd /oe Thanks & regards! dan |
