Posted on May 17, 2011 at 09:44It seemed that something wrong in str91x.s what type of controller you select? Do you modify the defaut str91x.s in keil?
Posted on May 17, 2011 at 09:44I set the parameters in keil, it is not must to set the parameter, and it work ok, maybe you should check your emi setting. the only problem I found is the speed. It is too slow, about 3MHz. Do you get faster?
Posted on May 17, 2011 at 09:44set the ram1 with the start address and the size, such as set start 0x3c000000 for Non-buffered cs0, and the size 0x80000 for 512KB size.
Posted on May 17, 2011 at 09:44For 8bit nonmux mode, with 66MHz PLL, I get 4MHz EMI CS0 access speed. and 8MHz EMI CS0 access speed with 96MHz PLL. the test code: __asm { TSTLP: MOV R0,#0x3C000000 LDRB R0,[R0] B TSTLP }
