I would like to know how do I attach gdbserver to my ARM Base FVP for debugging. All tutorials online explain using DS-5. I would like to use gdb since I am more comfortable with it. I already enabled networking on my FVP.
Thanks for your help!
Hello, I wrote an older blog on booting a Linux distribution on an FVP, which I believe still applies. See the command options used to enable networking etchttps://community.arm.com/developer/tools-software/tools/b/tools-software-ides-blog/posts/booting-linux-on-the-armv8-a-model-provided-with-ds-5-ultimate-edition-5-24-and-laterWhen Linux is booted, do you have network access? For example, can you ping any website from the FVP?PS please note there is a dedicated forum for questions related to simulation models:https://community.arm.com/developer/tools-software/f/simulation-models
Thank you for your reply,
Yes, I can ping any website and have networking enabled. I was even able to use wget to download files. Networking works fine, but my issue is hooking the gdb on my host machine to the gdbserver on the FVP.
Thanks for your blog link. I took a look at it and it uses DS-5 to run the FVP. I was hoping to avoid using external software. Are there any advantages of using the DS-5 software?
Thanks for the forum link also. I'll take a look there.
Hi Mohannad,DS-5 (and now Arm Development Studio) are the toolchains from Arm, hence my blog(s) on these products. However for this specific case of application debug, a standard gdb debug connection is used, and so it should work in the same way (though it is not something I personally have looked into). Is you set the IP address of the target in gdb as localhost, are you able to connect?RegardsRonan
I finally got it to work! It was a silly mistake from my end. Thanks to your blog, I noticed the bp.hostbridge.userNetPorts parameter in my script did not include an extra port for connecting the gdb server. It only had the ssh port. I am able to hook to it successfully now. I am so frustrated I never noticed this earlier!
Thank you very much for your help!
