New ContributorI am using an Arria-10 based SoC FPGA (10AS066H3F34) with fabric bit-stream encryption enabled (thus JTAG disabled). I want to use gdb debugger on the target. I am working on target remotely and cannot gdb remotely and gdb-server on target FPGA board. Has gdb been compiled for the arm-linux-gnueabihf platform? I see gdb-server has been compiled. How do others use gdb (not gdb-server alone) directly on target?
ContributorHello PeteHarbour,
If you have a linces of ARM DS* below, you can debug Linux application on Arm* DS with gdbserver over Ethernet.
Let us know if your expectation is different.

Linux Application Debugging With DS5

NOTE: Arm* DS5 has already dropped. But a procedure of debugging is almost same as Arm* DS. So you can refer to above link.
Thanks,
New ContributorHi IntelSupport,
Thanks for the answer. I am still using Eclipse DS-5 (community edition) for code development . I see the new Arm* Development Studio suggestion, I will look into that.
However, I am also interested in another option. My team is running code in customer field environments where specific conditions only occur on those environments. We are unable to run our products with additional open Ethernet ports (to support gdb data protocol transfer from gdb-server target to gdb host) on customer sites as our FPGA fabric design is bit-stream encrypted for security. We are hoping gdb has been built for the Arria-10 arm-linux-gnueabihf compiler platform (since gdb-server has already been built). Our goal is to run gdb and gdb-server on the Arria-10 platform (debug directly on target). We see there are Linaro versions of gdb built for arm-linux-gnueabihf, but they do not seem to run on the Arria-10 platform. Are you familiar with any Intel customers requesting to gdb debug on target directly?
ContributorHi PeteHarbour,
Thank you for the response and detailed explnation.
We understood your goal which you want to debug any program on A10 SoC with gdb and gdb server directly via SSH or Serial port.
Unfortunately, we have never heard the request.
But, we try to debug any program on the target.
Thanks
ContributorHi PeteHarbour,
We hope you did resolved the issue by yourself.
We also tried the gdb static binary below on Arria 10 SoC Dev Kit. It works fine.
https://github.com/marcinguy/arm-gdb-static
Here is an actual log of the GDB when debugged the hello world sample.

Lastly, we used pre-build binary below as Embedded Linux System.
