1 year ago I am following the setup for a flow sensor on Raspberry Pi 4B linked here. I followed the steps given in this link, but as they are using the archived repo, I am following the steps given in this repo. I am getting the above error when I run the rpi-source command in the terminal. It installs the kernel but while adding the files it is giving me this error.

1 year ago That's not enough information for 2 - what does uname -a report?

1 year ago After some experimentation I'm going to guess that you're on 32-bit Raspberry Pi OS with the current apt kernel and firmware. This equates to:
Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 GNU/Linuxi.e. a 64-bit kernel on a 32-bit userspace. It should be possible to compile kernel modules with this configuration, but it requires a cross compiler to be installed and used by rpi-source.
Try this:
$ sudo apt install gcc-aarch64-linux-gnu
$ export CROSS_COMPILE=
$ rpi-sourceNote that you may need to delete the linux-<hash> directory in order to get rpi-source to do anything,
You should find that rpi-source now runs to completion, just leaving you with the problem that the out-of-tree drivers are a bit old/broken. Apply the following patches to get them building:

export CROSS_COMPILE=aarch64-linux-gnu-Thanks a lot for your support, rpi-source compiled after adding the patch. However, the modules are not compatible with the kernel version I am currently running. I am adding the command and error message load the modules and instantiate the driver for your reference:

1 year ago I ran into the same errors, to finally solve it i ended up changing the OS to a headless 64bit instead of a headless 32bit RPi OS. When I did that I didn't need to run rpi-source as the build folder came included when I ran "sudo apt install raspberrypi-kernel-headers".
@chinmaydashp, I hope this helps your "Invalid module format" problem!
