New ContributorI am using Quartus-Prime along with the USB-Blaster to control my Device (using JTAG).
I want to control my device without using Quartus. Please help me with the public (BSP) APIs of USB-Blaster so that I can access it without the need of Quartus.
Also if we do not have any public APIs, what can be the alternate solution on controlling the end-device without Quartus-prime application.
BR,
Alkesh
Super ContributorHi,
so basically generic JTAG stuff. OpenOCD interface seems appropriate, either through Quartus jtagserver or third party drivers accessing USB Blaster directly.

New ContributorHello,
I am trying to execute the tcl commands few basic commands works as expected.
eg: Finding the available devices, opening a device, locking it, closing it, etc.
But was not successful in doing the scans (IR and DR scans), would like to know if you can help me with the exact commands supported.
Thanks,
Alkesh
Regular ContributorHello,
You may explore open source : JAM STAPL PLAYER as well.

Super ContributorHi,
"control my device" doesn't say which interface to FPGA core you are using. Presume you are talking about virtual JTAG functions like Source&Probe, In-System-Memory Content Editor, JTAG UART, Virtual JTAG IP.
USB Blaster and other programming cables are accessed through jtagserver. The client interface is documented here https://github.com/intel/libaji_client You need to install at least Quartus standalone programmer to have jtagserver available on a Windows or Linux computer.
Quartus tools are accessing jtagserver through a common client stack with sld_hapi.dll on top, unfortunately completely undocumented. You can list the exports to get an idea what it's doing.

New ContributorThanks for the update.
When I say "control my device",
I actually want to do all the operations (high-level and low-level) that are supported by the Quartus-Prime over JTAG-Chain Debugging.
High-level may include operations such as device-programming or device-configuration.
Low-level may include operations such as IR/DR boundary scanning or state transition of TAP-Controller, etc.
New ContributorWell, I tried an approach of having a .svf and executing it using quartus_stp.exe.
And unfortunately, it did not work.
I created a .svf file using python. Would be great if you can provide some insights on how to execute it.
Thanks
Regular ContributorHi Alkesh,
Could you share what the issue you're facing? Btw, there are no official public APIs for direct USB-Blaster access outside of Quartus-Prime. However, you have a few alternative options:

New ContributorHello,
I am using Quartus prime Standard version, with this is it possible to:
1. Execute the .svf file?
2. I do not have svf2jam.exe with this version, is it possible to get it ?
3. Quartus Standalone Programmer + jtagserver: how do I use this with python application. Do you have any example source?
Still I did not get the proper solution to work on my JTAG device. A quick response would be really helpful.
Thanks,

New ContributorThanks for the response.
Regrading the point number 3.
The url opens for Quartas prime Pro version. When tried to open for Standard it fails saying "404, page not found".
So does it mean that STAPL is not supported by Quartus standard version?

Regular ContributorHi Alkesh_shah,
There is a glitch with the download page. I will send the file to your email separately.
To answer your question: The JAM Player is a standalone utility and can be used to program devices with JAM/STAPL files, regardless of the Quartus version installed.
