Dear Firefly,
I am trying to compile a network driver for a PCIe card inserted into a RK3399 board.
I am facing three issues.
************************************
1. Issue with linux-headers for 4.4.16.
************************************
This command when I run on firefly Linux, I am getting the below error.
I would like to compile a network driver after the Linux headers are downloaded @ /lib/modules/<Linux_Version>/
# sudo apt installlinux-headers-$(uname -r)
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package linux-headers-4.4.16
E: Couldn't find any package by glob 'linux-headers-4.4.16'
E: Couldn't find any package by regex 'linux-headers-4.4.16'
Please suggest me what is wrong here,why the kernel headers are found for 4.4.16 version is linux in firefly board ?
And from where to download the headers for our 4.4.16 version of Linux?
************************************
2. Downloaded kernel mismatch: ************************************
Currently the firefly board has the linux kernel 4.4.16.
I downloaded kernel source (4.4.77) from the firefly repo which is not 4.4.16.
So when I compile the kernel (4.4.77) and compile the driver, the driver is being compiled but I am getting an error of version mismatch when the driver is inserted as below:
[15712.108550] r8168: version magic '4.4.77 SMP mod_unload aarch64' should be '4.4.16 SMP preempt mod_unload aarch64'
This is because, the Linux running on firefly is 4.4.16 and the dowloaded kernel is of 4.4.77 and driver is compiled using 4.4.77 kernel source.
Could you please point to me to 4.4.16 kernel source of firefly rk3399 board? If not available, how do i proceed with the driver compilation, please suggest?
************************************
3 Dmesg prints for PCIe
************************************
Is this the notable error? Why this error shown in dmesg log? please clarify?
