Solved: drivers for vcu

kiran1490 · ‎09-16-2019

I am trying to add vcu-modules(al5e, al5d and alcommon) to the linux-xilinx kernel. I am trying to make the drivers but i am getting error:

error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
.attach = al5_dmabuf_attach

i have no idea why i am getting this error. i am using cross compiler =aarch64-linux-gnu- and ARCH=arm64. please assist me. i am attaching the error log.

I am not using petalinux. I am using the linux-xilinx source code to compile the vcu models. Anyway the problem is solved. The reason for that error is I am using linux-xilinx of 2018.3 and using the vcu modules of 2019.1 release.

HI @kiran1490

Are you using petalinux?

If yes, you should follow pg252 chapter 12. There are receipes you need to add to your petalinux project to add the drivers.
