Hi,

From the address 0x7200 is correct. May I know if the address 0x7201 is correct? May I know if you are able to performed the testing until you observed that the content is incorrect which is matching with the SignalTap?

    Hi,

    I got this address from tool generated synthesis folder.

    .SECTOR1_START_ADDR (0), //hex value = 0

    .SECTOR1_END_ADDR (4095), //hex value = FFF

    .SECTOR2_START_ADDR (4096), //hex value = 1000

    .SECTOR2_END_ADDR (8191), //hex value = 1FFF

    .SECTOR3_START_ADDR (8192), //hex value = 2000

    .SECTOR3_END_ADDR (29183), //hex value = 71FF

    .SECTOR4_START_ADDR (29184), //hex value = 7200

    .SECTOR4_END_ADDR (44031), //hex value = ABFF

    .SECTOR5_START_ADDR (44032), //hex value = AC00

    .SECTOR5_END_ADDR (79871), //hex value = 137FF

    In this i am using sector4 start address for CFM1 and sector3 start address for CFM2. The above values are in decimal if i convert into hexadecimal it will give 0x7200 is the starting address for CFM1.

    No if i signal tap the data read out from the examine it is not responding. But if i give the original rpd data it starts giving the result,which means it is reading back the original data but if we examine through JTAG it is showing different data.

    Is there any encryption for reading the data through JTAG for security pupose.

    If we assume that the data written correctly but it is not triggering the reconfiguration, what might be the reason for this?

    Regards,

    Shiva.
