MAX 10 Configuration Flash Memory (CFM) how to write to it?

So after auto detect, you still see two devices in the chain and it still doesn't work?

After auto detect I have only one single device. To have two devices, I had to click in "Add file" and choose the `.pof` manually.

I don't understand. So you're saying when you add the programming file to the one device, a second device just appears out of nowhere? Can you right-click the extra device and remove it?

No. I start Quartus, open the programmer, click "Auto detect" and only one device appears which is associated to the `.sof` file. If I now click "Start" it programs and I get the green "Success" light in the top right.

With my old FPGA I was somehow able to program also the `.pof` and I want to do this now on this one. So now I click on "Add file" and select the `.pof` file. This creates the drawing of the second device, which looks the same as with my old FPGA. But now it fails to program.

I do want to program the two of them.

What if you double-click the existing .sof and select the .pof instead of using Add file?

In that case I obtain this other error:

Hi,

Thank you for contacting Intel community.

I found a similar case as yours from Intel community below;

Please have a look and let us know the update.

Hi Aiman, I saw that one. Does not work for me.

Can you try this;

Perform auto-detect from the programmer? The

programmer will detect the physical number of devices connected in the JTAG chain

on the board. Then right click at the detected device (that you want to

program) and choose “Change File” and select the .sof file to be add into the

device. Then perform the program. You can only program the devices on the board

that being detected by the programmer.

Hi,

What is the frequency used? Can you try to lower the frequency to 6MHz?

Is there any other changes that was done for programming the new FPGA compare to the old one?

Did you follow the pin connection guidelines?

And follow the Max 10 configuration userguide to program CFM.
