Altera Usb Blaster

Hello I cannot communicate with USB Blaster via Quartus II Software. I am trying to read Altera EMP7032SLC44-10 IC software. I need to get the software from inside the IC. I am connection to Al...

I can see the EPM7032S empty IC from the quartus program with Byteblaster. I can not see it from quartus with EPM7032S byteblaster that I removed from my device. because JTAG communication is locked.

I am deeply confused. You can detect device with Quartus Programmer and then you cant detect device with Quartus Programmer? Are you saying this?


When I auto detect the programmed IC with the quartus program, it gives the device not found error.

So now you can detect the IC but it gives you error? So which scenario are you saying? There are 3 different scenario. Which 1 is true. Or my understanding is not correct?


The fuse has to be blown for jtag communication of the programmed IC.

Once the fuse is blown, you cant detect FPGA using Quartus Programmer already. Thus I dont see it is valid in this point.


then I can communicate with the IC. I can get the pof file in it. Doesn't see JTAG link after IC is programmed.

Based on my understanding after several times of reading, it seems like you have blown the fuse and thus you cant detect the FPGA using Quartus Programmer. If this understand is correct, then i think what you have seen is valid.

    Hello, Yuanli S, No, you misunderstood me.
    1) There are 2 ICs. one is blank (new). one is programmed (inside the electronic device).
    2) The software of the EPM7032SLC44-10 IC in the electronic device has been damaged. therefore the device does not work.
    3) I have another replacement from the same product. I want to get the pof file from the IC in the solid product. copying this to the new IC to burn.
    4) But the IC inside the working product is encrypted. ie JTAG ports are protected, so the IC does not appear in the quartus program. (When I do Auto detect it gives the error IC not found).
    5) I want to read this IC in quartus program and get the pof file in it. I saw an explanation as follows in my research. After the manufacturer firm installs the pof software on these ICs, they can lock the jtag port of the IC so that it is not copied by someone else.
    6) How can I see the IC with software inside? I want support on this.
