    embedded Atmel and virtex-4 Using iMPACT tool over ICSP

    Hi everyone,

    I'm currently working with this Flash memory: @99AMD L320DT 90VI connected to virtex-4 which is connected to Atmel: Atmega128l

    I have failed to access Atmel over ICSP using iMPACT 14.7. Therfore, the console gives me errore such as: Cable autodetection is failed.

    How to solve the problem?

    Thanks in advance.

    Hi Klaus,

    The below figure shows roughly the block diagram of connections.

    Regards,
    Sami

    Hi

    JTAG and "IMPACT" is not connected?
    JTAG usually has TDO, TDI, TCK, TMS and maybe TRST...

    I know that impact can talk "JTAG", but are you sure it can AVR_ISP?
    Why didn't you use the AVR JTAG feature?
