I want to find out a method to readback the USERCODE of the FPGA via the JTAG download cable (USB-Blaster) on my PC side.
I had found the following topic about the error message (https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/soluti...), it seems that the ALTPLT1 is the driver 's name of the ByteBlaster cable.
If I want to readback the information by using the JAM STAPL player, do I must use the Byteblaster cable instead of the USB-blaster cable ?
Thanks a lot.
Unfortunately, the JAM STAPL does not support USB-Blaster. You may refer to https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/soluti.... The reason is that the JAM STAPL is use for embedded system.
So I would recommend you to use quartus_jli if you would like to use USB-Blaster.
