A PROBLEM ABOUT THE master selectmap mode IN XC2V3000
Hi,i got a problem,its about the master selectmap mode,hope anyone can help. Specific questions are as follows: When I use master serial mode to configure the XC2V3000（prom is XCF16P） , the connection is referred to figure 4-8 of UG012 ,i connect the XCF16P D0, CCLK, CE, CF, OE/reset and FPGA Din, CCLK, DONE, PROG_B, INIT_B separately, and connect FPGA PROG_B and INIT_B with pull-up resistor. In this pattern: 1,PROM configuration file is .Mcs format and is written in JTAG mode. 2, M0, M1, M2 mode selection is adjusted to 0, 0, 0. it can configure successfully.
However, when I use the master selectmap mode, the connection is referred to figure 4-12 of UG012. Based on the master serial mode 1, increased the connection of D1-D7 data interface, increased the connection of both BUSY pin; 2, the M0, M1, M2 mode adjusted to 1, 1, 0; 3,keep RDWR_B and CS_B low all the time; 4, the configuration file in PROM has no change, relative to the master serial mode. At this point, you can't configure it successfully, so how do I do it to complete the configuration of the master selectmap mode?
