Max 10 doesn't start

Hello, I have a problem with the max 10. I have programmed it in the flash memory the code, but I am not able to start the FPGA. I leave you a part of the schematic of the configuration pins. ...

Hi, it is not starting with a proven design? After programming and or at power up?

Try a simple design can be tested on board, IE an LED connected to JTAGEN, generate and load as SOF without programming Flash.

Test Config_done and nConfig level, if not High test all other configuration input for high level.

In case of failure try add 4 more resistor + 1 cap:

10 KOhm pullup to CRC err (known) TDI TMS (less importance)

1 KOhm pullDOWN to TCLK (Possible caveat)

10-100 nF cap from CLR_n to ground

    I cannot modify message...

    About CRC Error, I checked two of my design, is connected to logic without pullup.

    Please try verify flash and tell us about what is on console.

    From what I remember I got troubled by some pin driving nConfig, ConfigDone, nStatus, are these pin free on your design or shared to?

      Hello,

      Sorry for the delay. I have had not enough time to proof it. This night will test it and comment you.
