I would like to run some individually compiled kernel files (i.e., drivers) on the J721E platform. What kind of development environment should I set up for this? Do I need to configure both PROCESSOR-SDK-LINUX-J721E and PROCESSOR-SDK-RTOS-J721E? Since the drivers involve Linux kernel code and the J721E kernel version is 6.1.46-g5892b80d6b, do I need to download the corresponding Linux source code myself?
Previously, on other development boards, I had a ready-to-use development environment (cross-compilation toolchain and Linux source code), which allowed me to directly cross-compile standalone driver files (.ko files). I’d like to know how to set this up for the J721E platform.
thanks
Thank you for your help. I have preliminarily set up the cross-compilation environment and can compile a user-space executable program for the ARM architecture.
However, when compiling the kernel, I encountered an issue. During the make process, I received an error stating that the kernel configuration file include/config/auto.conf is missing.
How can I resolve this issue?
Below is my Makefile：
