Problem for programing MAX7000

Hello, I have electronic cards with 4 MAX7000 FPGAs which work perfectly and which I can program without any problem. The 4 FPGAs are in a JTAG link (TDI-TDO) the first 3 are MAX7128S and the la...

    I understood what is wrong.

    In fact, it is the verification part of the programmer that is buggy or illogical in its operation.

    I spotted two flaws:

    To check any fpga in the chain, there must be at least the first .pof file in the chain in addition to the .pof file to be checked.

    But it's not this weird thing that blocked me. To do a check of any fpga in the chain all .pof files, if put in the chain must be equal to what is in the fpgas on the card, even if it is not the one that we want to check. Because in this case the programmer does not even try to launch a verification and that is what stopped me, so much I wanted to understand.

    The solution is very simple, you can compile with any version, anything, you must first not try to check anything and simply start programming.

Precisely, 20 years ago I used Max+plus on W98.

Now I'm on Quartus and XP, W7 and W10.

And I also use the Terasic Blaster USB which works very well on all my boards with one or more Altera Max7000 FPGAs in a chain.

I also have an Altera USB Blaster which only works on boards with a single FPGA.

I will follow what you suggest, and I will see.
