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 |

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: i.e. a 64-bit kernel on a 32-bit userspace. Try this: Note that you may need to delete the 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.

Thanks a lot for your help. Yes, I am using the 32-bit Raspberry Pi OS with the current apt kernel and firmware and got After following the steps, I am still getting the same error. I am adding the entire terminal log for your reference. |

Sorry - I paused writing my instructions to check the compiler string then didn't complete it. I should have said: |

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: |

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! |
