Problem is that within Yocto/Linux I need to build it whatever package i need and there is no package manager for install such as  apt-get.

but I did reset my PC, MS Visual, and target linux imx and then I’ve been successful.

It seems to me that old setting is somewhere cached – so some cleanup needed when new target on same IP address is needed but i’m just guessing.

Thank you very much for your support!

Hello,

I just rebuilt the linux image and want to continue debugging but I hit the issue of establishing connection to target:

SSH: Connecting…
SSH: Error
Connection error: No connection could be made because the target machine activel
y refused it 10.171.88.193:22
Connection to target failed. Please use Tools->SSH Host Manager in Visual Studio
to diagnose it.

I can ping to my target both from Windows machine and Linux build host.

Visual C++  says:

Cannot connect : No connection could be made because the target machine actively refused it 10.171.88.193:22

I got the VisualGDB working. I put the target on the same network as Linux Host & Windows machine and now I got this working!!!

 

[peter_cz]

Nope. can’t access it from Linux Host,  I have no response on my target by issuing telnet> open 192.168.0.100 no response  on target side.

[peter_cz]

my observation:

On my target (IP: 192.168.0.100) I run

gdbserver :2000 LinuxProject1

got response

Process LinuxProject1 created; pid = 535

Listening on port 2000

on my windows machine run Tera Term where setting is

TCP/IP Host: 192.168.0.100

telnet TCP port#2000

Protocol:UNSPEC

then I got response on target:

Remote debugging from host 192.168.0.101

 

[peter_cz]

It seems gdbserver on target got freeze. Since cmd : gdbserver :2000 myproj

Then got response listening at 2000 but then board has no response and can’t quite gdbserver. Any option to run gdbserver with needed?

[peter_cz]

I’m able to establish SCP (WinSCP) connection Win -> Target (192.168.0.100) but not telnet 192.168.0.100:2000 while I’m running gdbserver :2000 LinuxProject1 on my target machine. My build (host, Linux) machine (10.171.88.187) supposed to be on the same network as windows one (10.171.88.158) but target is connected via local wifi as PC-Windows <-> Target via wifi router as AP.

[peter_cz]

Does not work.

[peter_cz]

After I do right click and from context menu choose Debug -> Start New Instance then I got dialog “Select Process to attach debugger to” then Debugging failed whatever process I choose.

Otherwise not selecting a process i have almost nothing happening but within VisualGDB Program Output it’s displayed

Process /home/root/LinuxProject1 created; pid = 559
Listening on port 2000

And really nothing is happening, no debug, debugger is not started and no stepping thru the code etc…

 

[peter_cz]

reading your tutorial I can’t get behavior

http://visualgdb.com/tutorials/linux/edison/

@ step 13. I can’t get output to “gdbserver” window is not started and code does not enter debug mode.

[peter_cz]

I did installed gdbserver on my target, I got “Failed to start GDB server session” error message

[peter_cz]

Thanks for your help. Now it seems can compile and my test program resides on host. and I can’t debug it:

gdbserver is missing on “192.168.0.100” (target).

 

So now I am looking for a way how to get gbserver running on target.

Second question is about configuration and since compiled program resides at host

VisualGDB: Run “make CONFIG=Debug” in directory “/tmp/VisualGDB/c/Data/Projects/Vision_iMX/vc_projects/LinuxProject1/LinuxProject1” on “userbanme”@10.171.88.187 (SSH) but I’d like to have on my target machine. Is it possible have that “automatically” donwloaded to my target machine?

Thanks for your help.
