Matrix Multiplication Linux User Space Zynq7000
berkdi...@gmail.com
I am developing an AMP solution (Linux master, FreeRTOS slave) for my thesis, and so far I am able to run matrix multiplication demo but I can't modify the Linux master code. I have a couple of questions and every possible help is much appreciated.
1) I found the source code for master application at (https://github.com/OpenAMP/meta-openamp/tree/master/recipes-openamp/rpmsg-examples/rpmsg-mat-mul) and I created a new app from c template called "mymaster" by petalinux tools. My initial plan was to copy the source code into mymaster.c and after compiling it everything should have been worked.
2) After compiling it, I got an error; "#include <linux/rpmsg.h>" no such file or directory". I solved this issue by downloading the linux header files and putting a variable to that folder as CFLAGS, in Makefile. But now I got the errors down below.

3) How can I solve this issue, all I want is to be able to modify linux master side of the example applications, since I am already able to modify the FreeRTOS side, I will be ready to develop my final application. Thanks in advance for your help and answers. All are much appreciated.

From your log, it looks like some Linux header files are missing in your sysroot. But from your 2), you don't use yocto to do crosscompile for your linux kernel. Don't know how this can work. you can try petalinux-build or just yocto bitbake to build both kernel and user app.

1) I can run AMP examples provided (echo_test and mat_mul_demo)
2) I am able to modify the slave code from xsdk, creating the .elf file and putting it into recipes-apps/<app-name>/files directory and editing the bitbake recipe, works perfectly.
3) I want to be able to modify linux master code of these applications as well and I found these codes from meta-openamp repository. How can I do it, can you please explain step by step maybe ?
Since my deadline is approaching for the thesis, any explanation will be greatly appreciated. Thank you so much in advance Wendy.
Sincerely,
Berk

Thank you very much for your response Wendy, however after trying many hours, I am still not able to overcome the issue. Let me explain it very simple to you:
1) I can run AMP examples provided (echo_test and mat_mul_demo)
2) I am able to modify the slave code from xsdk, creating the .elf file and putting it into recipes-apps/<app-name>/files directory and editing the bitbake recipe, works perfectly.
3) I want to be able to modify linux master code of these applications as well and I found these codes from meta-openamp repository. How can I do it, can you please explain step by step maybe ?
[Wendy] you can add meta-openamp to your layer, and then build the rpmsg-echo-test first to see if it works
and then you can create your own app based on the example.
You can try copy the recipe and the source file and makefile and make update.
Since my deadline is approaching for the thesis, any explanation will be greatly appreciated. Thank you so much in advance Wendy.
Sincerely,
Berk
