SDK remote debugging a linux app

Former Member
Former Member over 12 years ago

Hi all,

I have followed the CTT_14_4 Tutorial for ZedBoard and in the example 5.4.1. (Controlling LEDs and Switches in a Linux App) I cannot perform the remote debug operation.

I create in SDK a Linux C empty application associated with the exported HW platform and follow the steps from the tutorial.

Initial Linux SD boot from Zed is made OK and I get the zynq> promt in the serial terminal, but when next I programm the FPGA with the exported .bit file from PlanAhead, the serial terminal is blocked. Is not explained in the tutorial but may be normal... Then, I continue defining the Debug Configuration and when establishing a new SSH connection to ZedBoard, after login as root to Select Remote C/C++
Application File in ZedBoard root file system I get the following error:

"RSE Subsystem Operation has encountered a problem. Failed to connect sshd on 192.168.1.10:22".

Before programming the FPGA I checked out that ping 192.168.1.10:22 was responding and ZedBoard is configured with the correct IP.


Do you know how to establish a correct connection to ZedBoard? Have you got any idea that could help me?

Thanks for any help in advance!!

    Hi jmassol,

    The message "RSE Subsystem Operation has encountered a problem. Failed to connect sshd on 192.168.1.10:22" indicates that SDK is unable to connect to the target board with SSH and SFTP.

    Are you running Linux already on your target ZedBoard?  If so, which flavor of Linux are you running? Is is something you built yourself or are you using one of the Release images from the Xilinx Wiki?

    http://www.wiki.xilinx.com/Zynq+Releases

    Whatever the Linux flavor, you will need to have an SSH daemon and SFTP server running under your ZedBoard Linux in order to connect using the Remote System Explorer (RSE).  This is something covered in Lab 4.1 and 4.2 of our "Implementing Linux on the Zynq-7000 SoC" training on the Training page:
