Hi Alex


Is it possible if you could zip your project and share it with me.

I could not find any reported issue or any solution to thee issue.

Let me try to reproduce the issue and hopefully find the solution for you.

Hi,

Sorry it would be very difficult to share this for my permission limits.

I can provide some information instead:

My environment is as following:

kernel：6.0.0zImage-221234-g968dfc188ae5 linux-socfpga.

the download link is :altera-opensource/linux-socfpga: Linux development repository for socfpga (github.com)

My toolchain is arm-linux-gnueabihf-

I make the kernel by the follow order:

make ARCH=arm socfpga_defconfig

make LOCALVERSION=zImage ARCH=arm -j <n>

To use the <asm/io.h>, you may need to link the "asm-generic" with "asm" for after making the asm file didn't exist.

You can use this toolchain by visit this website: https://www.acmesystems.it/arm9_toolchain

I attached my personal make file.

Reguards.
