I have rebuilt the my Yocto/Linux and now I do have “crt1.o”, “crti.o”, and “crtbegin.o”.

They are located within

/opt/fsl-imx-x11-4.1.15/sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/lib/

but tool says “Toolchain Test Failed”

Hi,

Please specify the “–sysroot=<SDKTARGETSYSROOT>” argument in COMMONFLAGS in VisualGDB Project Properties.

You can find more details in our Edison tutorial showing how to configure a similar Windows toolchain. The only difference is that in the Edison tutorial the toolchain runs on Windows and in your case it runs on a remote Linux machine.

I’d like to have running toolchain on windows as well, but I need to know how. I have toolchain on Linux host.

Hi,

Building a Windows toolchain is not straight-forward. We provide basic build instructions here, however it usually never builds out-of-the-box and requires some patching dependent on the compiler version and platform.

We also offer a toolchain building service: you can send us your Linux toolchain and we could build a Windows equivalent. Simply contact our sales with more details to get a quote on that.

is there a way somehow to copy it from what is already built on my server host instead of Building a Windows toolchain?

Hi,

Sorry for the late reply. The error you are observing happens because some parts of the code are built with the “hard float” ABI and others with “soft float”.

You can resolve this by adding the following flags to COMMONFLAGS:
```
-march=armv7-a -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9
```

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.

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

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.

Hi,

Normally VisualGDB will automatically deploy everything when you start debugging.

If GDB reports the “Connection timed out.” error, most likely either the gdbserver failed to initialize properly, or your firewall is blocking the connection. Does the gdbserver window in Visual Studio show any errors, or is it reporting a successfully opened socket on port 2000?

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…

If VisualGDB asks for a process to attach, it means that your debug settings have “Attach to a process” selected. Please open VisualGDB Project Properties and change gdb launch mode to “Debug a new instance”. This should resolve the problem.
