Program: Quartus II Programmer Only
Device: USB Blaster Rev C. Here is my problem: Right now I can use the USB Blaster to configure and program specific chips on board but what I want to also do is be able to download the existing file from on board chip. Basically I want to reverse the process. I want to give myself the original firmware that exists on-board so that I have something to fall back on just in-case. I first do auto-detect and I get my list of programmable chips. I then can only Program/Configure or Blank-Check all while under JTAG mode. What do I have to do to be able to save the firmware/file from the on-board chip? Do I need the complete Quartus II software/Web edition/Student edition? Thank you in-advance連結已複製

It's very easy. You can't read back ("examine") the CPLD data after performing autodetect, probably, because the ID information is insufficient to determine the configuration stream size or similar issues. But after adding the same device with "Add Device" function and deleting the autodetected one, you can. May be, you can find this information in the Quartus Handbook, but in my opinion, it's more easy to check it out.
