I am using XEM3001 and RAM3001 board. I cannot write and read from the memory (SSRAM) using just one word (I am trying the most basic) and testing on LEDs. What could be the problem. I am generating all the signals for the SRAM from my simple control unit. Could it be that the power from the USB is not enough? Also in the RAM3001 document page 7 mentions the two pins p[2] on JP3 pin15 and p[1] on JP3 pin33. What are these pins cuz the SSRAM datasheet does not say anything about these?
totally :frowning:


The matter is resolved…it was strange. I was giving clk from the FPGA and it will not work…i just switched the clock from the FPGA to the PLL and it works now:p
