    yes and it works

    I also check the verify checkbox and everything was ok

    but the board still remained in the previous state ( turn on on weak light)

    The programmer screenshot looks like AS programming has been succesful. In case of doubt, you are also able to verify the EPCS data. Sucessful programming doesn't imply, that the code is valid for the respective FPGA, however. But that's nothing we can help with. Did you try to run the same code through (volatile) JTAG programming?

    today I tried to burn again with two other cards

    one de2-70 and another de2-35

    I failed in both attempts ... is it even possible to burn with the

    as-programming mode?

    The burning process still doesn't work I did everything that was said in the manual but nothing

    In quartus there is no warning and as far as he consider everything is ok

    But I didn't get the code to burn on the card instead all of the lights or turned on in a weak light

    I added a screen shot of the programming window

    Hope someone could help

    hi

    I followed the manual but when I press start I got this massage

    "Cannot start device configuration because no programming options have been selected for device chain"

    what can I do?

    Refer to the user manual chapter "Configuring the EPCS16 in AS Mode"

    thanks ,

    I did examine the schematic (wasn't easy to find) but I didn't thought about the minimum voltage needed to activate the regulator.

    so I guss that's way all of my gpio connections didn't work.

    do you know what do I need to do in order to burn my code into the DE2 memory execpt from switching the switch to prog state ?
