Using Win 10, Quartus 20.1, USB blaster and arria 10 device.
- I can program a pof file in the flash device (AS mode)
- I can to program a sof file in the fpga (JTAG mode)
- I can NOT program an ekp file in the fpga (JTAG mode)
I have also tried with the command line tool, result is the same : windows pops up "jtagserver.exe" is dead and the console shows:
Error (209034): Can't find JTAG Server
Error (209053): Unexpected error in JTAG server -- error code 44
Error (209053): Unexpected error in JTAG server -- error code 33
Error (209012): Operation failed
The required box in the options is checked. Updating the USB driver (was already the latest one) did not solve the issue.
Any help appreciated
Thank you for contacting Intel community.
-By command line tool, are you referring to the solution below:
-Have you also try with another USB Blaster?
-Also, can you try with the latest version of Quartus? You are currently using Quartus standard 20.1?
-We also have some problem with USB Blaster previously, you might want to download the patch from below;
Thanks for the tip about the digital signature, I have previously faced this issue. I did solve it using the dirty solution (bypassing the windows signature verification). I can program a lot of devices with my version of software/hardware so I think the driver is working well.
The question was why programming an EKP file (and only ekp) kills the jtag server. Re-reading the AN556, I found:
The .ekp file has different formats, depending on the hardware and system used for
programming. There are three file formats supported by the Intel Quartus Prime
• JAM Byte Code (.jbc) file
• JAM™ Standard Test and Programming Language (STAPL) Format (.jam) file
• Serial Vector Format (.svf) file
Only the .ekp file type is generated automatically from the Intel Quartus Prime
software. You must create the .jam and .svf files using the Intel Quartus Prime
software if these files are required in the key programming
So I tried to generated a jam file and program it. Everything works fine now. This topic can be closed.
