Suspected that it have to be like that, but hoped that I can avoid compiling the whole kernel... Well, the struggle continues. Thank you for the valuable tips!

I thought it was pretty clear, that I'm trying to build the module on the very same box, running the very same kernel version: 5.9.10-rk322x And I was left with the impression, that I need BOTH kernel headers AND sources to build it. The initial install image is not that important, as long as it's stable enough to boot and operate normally, until I switch to another kernel - one, for which I can find BOTH headers & sources. I guess I'll have to continue the struggle with other kernels... Pitiy, because 5.9.10 is tempting as a current "bleeding edge". 5.9.11 is flagged as broken as of now...

@jock I don't need the whole kernel, just the mn88472.ko per this kernel. That's why I ensure the system has the kernel running, sources an headers for it, then try to compile the minimum of it, following the dependencies, of course. However, vermagic of the pre-compiled modules, which came with the running kernel, differ from the newly compiled ones (headers & sources obtained via armbian-config)... And the box is not "in production", but a PoC still, so I can start from scratch whenever I want...

@jock Short status report on my case: 1. The only package - sources + headers - I've been able to obtain was for 5.9.10-rk322x on top of Armbian_20.11.0-trunk_Rk322x-box_buster_current_5.8.12_minimal.img.xz image (your build). 2 Prepared the build environment by: - copying the /boot/config-5.9.10-rk322x to .config - copying the Module.symvers to source build folder - make oldconfig - make menuconfig - selecting/enabling (*) the respective PANASONIC MN88472 driver - make scripts - make prepare - make modules_prepare - make -C . M=drivers/media/dvbfrontends also - make drivers/media/dvb-frontends/mn88472.ko - copy the built driver module to /lib/modules/5.9.10-rk322x/kernel/drivers/media/dvb-frontends/ - depmod - modprobe mn88472 dmesg log (excerpt): modinfo shows: modprobe mn88472 modprobe -f --force-vermagic mn88472: For example, the vermagic for dvb_usb.ko module (embedded, pre-built): Any ideas how to proceed further are much appreciated!

Thank you for your reply! Actually, with this image: Armbian_20.11.0-trunk_Rk322x-box_focal_current_5.8.9_desktop.img.xz the MXQ Pro 4K box (RK3228A) also works stable enough. However, by some sort of a comparative analysis, I've reached to a conclusion that the demodulator module - mn88472.ko - driver is missing from the kernel. The tuner is discovered: but half of the necessary FW is being loaded, only dvb-usb-dib0700-1.20.fw for the USB interface. The demodulator FW - dvb-demod-mn88472-02.fw - presumably, requested by mn88472.ko driver, is not. I guess I have to compile the whole kernel, just to get this armhf kernel driver module per the specific kernel version. So, during the config/compile process, what other options/tweaks are MANDATORY to ensure the kernel (and modules) are suitable to work on RK3228A? Thank you for your engagement. Stay safe, healthy and happy!

Greetings, Based on this post: I would like to enable the drivers for XBOX tuner in legacy kernel (e.g. 4.4.194 or Armbian_20.08.1_Rk322x-box_focal_legacy_4.4.194_desktop.img.xz image). Excerpt from a dmesg on a working x86 system: Would you, please, provide some guidance how to do that? Maybe this would be the way... ? TIA!

Apologies for the trivial question, but... How can I upgrade the whole image, for example from Armbian_5.77_Aml-s905_Ubuntu_bionic_default_5.0.2_20190318.img to Armbian_5.84_Aml-s905_Ubuntu_bionic_default_5.1.0-rc1_20190507.img especially when it's installed on internal eMMc... ? Thank you in advance for your replies and apologies for the inconvenience caused.
