hello @Nick A, have you read the last post i posted? When i was messing around on my box, i saw that the box only have 1200mhz freqency (note that this is allwinner h313) while h313 max freq is 1350mhz, and mine is 1200mhz, is the h313 nerfed by the firmware? Or anything else? edit: full cpu formation here

Find a DTS that uses compatible="waveshare,rpi-lcd-35" and try again (I don't use that LCD, so I am not sure... but I know it is special because it contains a SPI-to-parallel chip)

Try the devel repo: https://github.com/lwfinger/rtw88

Thanks for the suggestion, I appreciate it. Unfortunately it didn't do anything. I've tried the args one at a time, combined, still nothing. One thing I noticed, I can consistently get the nvme to properly show up, during the first boot of radxa's image. (ie. flashing the radxa image to an SD, booting for the first time to the desktop, the nvme will be detected and work properly). Rebooting after that is a hit or miss and generally only cold boots sometimes work. I also tried the args you suggested in the radxa official image and still the same. Btw for everything I mention, the armbian SPI image was installed. My only assumption is that some irrelevant delay related to the first boot, gives time for the nvme to initialize? On subsequent boots I get "pcie link fail" during boot, and again, lspci works, lsblk doesn't. Also I would like to use armbian ubuntu desktop which I can't at the moment, since the noble gnome image doesn't boot at all.

In the meantime and in order digging further I've switched to gcc-13 to build module with the same version as the kernel : root@orangepiplus:/mnt/sda2/src/linux-6.15.4# gcc --version gcc (Debian 13.4.0-1) 13.4.0 Then I've downloaded headers with armbian-config to : /usr/src/linux-headers-6.15.4-edge-sunxi and proceeded with rebuild Using Official Headers cd /mnt/sda2/src/linux-6.15.4 make clean cp /usr/src/linux-headers-6.15.4-edge-sunxi/.config .config sed -i 's/^EXTRAVERSION =.*/EXTRAVERSION = -edge-sunxi/' Makefile make olddefconfig 787 make menuconfig 788 grep -E 'CONFIG_RTW88_CORE|CONFIG_RTLWIFI|CONFIG_RTW88_8821AU' .config make modules_prepare cp /usr/src/linux-headers-6.15.4-edge-sunxi/Module.symvers . make M=drivers/net/wireless/realtek/rtw88 modules -j$(nproc) sudo cp /boot/System.map-$(uname -r) /mnt/sda2/src/linux-6.15.4/System.map root@orangepiplus:/mnt/sda2/src/linux-6.15.4# sudo make M=drivers/net/wireless/realtek/rtw88 modules_install make[1]: Entering directory '/mnt/sda2/src/linux-6.15.4/drivers/net/wireless/realtek/rtw88' INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_core.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822b.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822bs.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822bu.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822c.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822cs.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8822cu.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8723x.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8723d.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8723ds.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8723du.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8821c.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8821cs.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8821cu.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_88xxa.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8821a.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_8821au.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_sdio.ko INSTALL /lib/modules/6.15.4-edge-sunxi/updates/rtw88_usb.ko DEPMOD /lib/modules/6.15.4-edge-sunxi make[1]: Leaving directory '/mnt/sda2/src/linux-6.15.4/drivers/net/wireless/realtek/rtw88' sudo depmod -a But the resulting module failed loading again : root@orangepiplus:/mnt/sda2/src/linux-6.15.4# sudo modprobe rtw88_8821au modprobe: ERROR: could not insert 'rtw88_8821au': Exec format error Aug 24 12:08:53 orangepiplus kernel: module rtw88_core: .gnu.linkonce.this_module section size must match the kernel's built struct module size at run time It proves a structural mismatch again. Armbian built the 6.15.4-edge-sunxi kernel using Ubuntu's GCC 13 likely with plugins. GCC plugins randomize or instrument the layout of kernel structures — including struct module. It means, that you cannot reproduce the exact struct module layout unless you use the exact same GCC plugin configuration — which is not available to end users! Could it be fixed and what is the right approach to adding missing in-kernel modules from kernel sources or headers ?
