vivado sdk cross compile tool chain asm path not include

[eleicoto@outlook.com]

I'm using vivado 2018.3 and petalinux 2018.3 for my project.

I have generated sdk/sysroot and use vivado sdk to include it. The header file I need to use is already in serval asm / asm-generic folder(dmaxxx.h)

But the problem is that when I'm trying to build my project, it seems like the toolchain couldn't search all those asm||asm-generic||arch/arm64/asm path automatically, so it always pops an error telling no asm/xxx.h, but it does exist in other asm folder.

I'm using ZCU104 and build app for a53

Thanks!!!

Can you add the sysroots in the miscellaneous in the C/C++ build settings:

This method is wrong 

In order to use dma in userspace the first thing you should do is build a kernel module for dma driver then compile your userspace code

Chapter 4 in the above link is the right example, not Chapter 3
