The 6671 board must not to boot.

Hi All,

Use the 6678 EVM board has created a board.

JTAG connection, normally write programs to IBL files(EEPROM51.BIN) and SPI NOR memory.
However, should the SPI boot. DDR3 memory is operating normally.
If you read the GPIO value is 0x980B is read. But I read the DEVSTAT register the value 0xFFFF is read.
Why does the same? The accompanying diagram.

It did not put an FPGA in the EVM board. John does the problem is with the Reset or Power Sqeuence?

    Hello Gyosun,

    Since the DEVSTAT register does not show the proper boot configuration value, there might be a issue with device initialization. I would like you to ensure that the power and reset sequence is proper as mentioned in the device data manual. If possible, please share the scope capture of all the power rails and reset signal from your board.

    In your design, i see all the pins like POR, RESETFULL, RESET are tied together. But as per data manual, the RESET pin should not be tied together with the POR pin. Please refer section 7.5 Reset Controller in the device data manual for proper understanding about various resets.

    Regards,
    Senthil

    Hi Gyosun,

    I am not clear on the issue. Are you able to boot from SPI on custom board? Are you able to program the binaries on SPI NOR?

    Thank you.

    hi Senthil,

    Modify the glue logic board was tied evm test all reset.
    Power enable pin is also related to a sequence from the beginning, regardless of the evm also enable the board was operating well.
    Except that unnecessary, it was not so configure the hardware.

    DEVSTAT register is 0xFFFF thing out what's the problem?

    Thanks,

    Hi Raja,

    Nice to see you again.
    You can write to the SPI Nor flash using JTAG on board, we have created.
    Only cash will both normal boot operation.

    What's the issue sequence or other settings issue?

    Thanks,

    Turn the Google Translator in English there 's a non-smooth part.

    It has been successfully downloaded.

    Full sheets of chips made board, he was soldered to the EVM board has booted fine.

    The problem is that I get to 0xFFFF in the DEVSTAT register 0x980B come.

    Thanks,
