Hi,
Thank for the clarification. It seems like power supply is the issue for this.
This is what I want to do; I want to read the software of the IC that I removed from the device.
May i know which software are you referring to? Are you referring to image file in FPGA? Please clarify.
but IC jtag ports are disabled. Is there a method to enable jtag ports?
Which IC JTAG Port are disabled? I dont get it. Now your FPGA is able to be detected by USB Blaster after you have provided sufficient power voltage. You should be able to program image file such as SOF, JIC into the device already.
