Hi,
I developed for embedded systems many many years. Until now it was always by using a host and cross compile for the target. Connect to target by some debugging port, download and debug. The well known bare-metal programming flow I guess.
But now we have processors that need an OS and containers. I did a lot of reading and watched tutorials. I understand it is still preferred to program and cross compile on a host computer. But what I do not understand is how to deal with libraries.
Suppose I want to use OpenCV on the target. I assume I have to install OpenCV on the target. But how does the host know about the OpenCV lib I installed?
Is there some tutorial that explains the complete development flow including the use of libraries?
(I plan to use the Verdin IMX8M-PLUS on the Verdin Developer Board)
Unfortunately, this does not make thinks much more clear for me.
Firstly because this example is based on Visual Studio which is (if I understand correctly) not supported anymore. And for Visual Studio Code things are differently.
Secondly because libgpiod is already part of Torizon. But how to deal with libs that are not? Like OpenCV.
How do we install libs on the target when dealing with containers? How does the crosscompiler know about the lib. This is still unclear to me.
I’m rather new to Linux.
What is iterative mode and how do I open container in this mode?
What do you mean with call the libraries as normal?
How do I install the OpenCV library. I think I have to get the code from github and compile it.
Should I do that on target or on host? Or both? The process and how compiler/linker and runtime do know about it is still not clear to me.
