LAN743X Module loading issue in nano jetson

Hi Support team,

I have build LAN743X driver in jetson nano board.

  1. I have enable its driver as a module.(CONFIG_LAN743X=m)
  2. Driver is build successfully on my target board.
  3. I have found .ko file on below path.
    ls /home/cimcon/linux-master/drivers/net/ethernet/microchip/lan743x.ko
    4)sudo insmod lan743x.ko
    insmod: ERROR: could not insert module lan743x.ko: Invalid module format

5)sudo modprobe lan743x.ko
modprobe: FATAL: Module lan743x.ko not found in directory /lib/modules/4.9.253-tegra

cimcon@cimcon-nano:~/linux-master/drivers/net/ethernet/microchip$ ls /lib/modules/4.9.253-tegra/lan743x.ko

file lan743x.ko
lan743x.ko: ELF 64-bit LSB relocatable, ARM aarch64, version 1 (SYSV), BuildID[sha1]=5a7c29d8caee8e415c0926e30fb78bc9df7a7aa0, with debug_info, not stripped

Please provide some solution How can load it??

I have moved and tagged this topic with Jetson Nano. This will help it get the best attention.

Also rebuild the kernel image on the same device again and you shall be able to insmod this ko file.

Hi Team,

I am using Nano jetson kernel 4.9 tegra. It is not supported LAN7430 driver So Can you help me for that?

Is nano jetson support any other kernel version ?

My driver is successfully build and load. but I am facing some issue for not detecting driver in kernel. I have attached dmesg log for details.
