    Can't help with the firmware problem as I've not run 5.0.0-rc4 but can you expand on the WiFi-regulatory.db issue and any fix. I've had intermittent issues with wifi AP's and this message in dmesg / syslog. Thanks.

    The answers are in this forum but 1. see https://forum.armbian.com/topic/7930-armbian-for-amlogic-s9xxx-kernel-41x-ver-555/?do=findComment&comment=68879 2. see /boot/config* on the target tv box. 3. depending on changes, you just copy from the buildhost modules into /lib once you've tested them and copy arch/arm64/boot /Image.gz to /boot/zImage

    I'd try the .dtb filename your using from another .img build (more recent). I've found this works for me. Comparing the decompiled .dts source, the only difference was positioning of some statements in the structure (TBH, I pull the /boot and /lib/modules/ files out of the image when a new one is released).

    I'm using a meson-gxbb-p201.dtb box and have noticed issues from version to version (i.e. sound on kernel 4.20.2) as well as screen powered off. Had to use systemctl restart lightdm.service to get the screen back. Problem are fixed by using the dtb from Armbian_5.73_Aml-s905_Ubuntu_bionic_default_4.20.2_desktop_20180129.img.xz (even though I'm running 4.20.2-aml-s9xxx kernel)

    What is the current status of AMAUDIO/AMAUDIO2 (audio through HDMI from 3.14.29 amlogic kernel source) into 4.2x or NEXT 5.0 kernel builds for S905?

    You will need to mount (/mnt) a partition in emmc with enough space and issue: dd if=/dev/zero of=/mnt/512mbfile.bin bs=1024 count=512000 which will report speed in bytes at the end. Its difficult to a read test due to the caching element but dd if=/mnt/512mbfile.bin of=/dev/null bs=1024 will give you the speed of RAM if you run read test after write!

    Your correct but under android or older 3.14.x kernels, aml_sd_emmc presents all the flash partitions laid out but with more recent 4.x and above kernels, meson-gxbb-mmc is one device according to /proc/partitions

    I've not installed on emmc as I've never used usb burning tool to unbrick a tv box. Not impressed with the write speed when mounting existing emmc flash partitions. For example on my T95 S905, the data partion mmcblk0p14 based on the android boot information can be accessed with mount -t ext4 /dev/mmcblk0 /mnt -o loop,offset=2545942528,sizelimit=5272240128 Can't suggest much with emmc apart from it will probably be a .dtb issue.

    If I had problems with a driver, I'd probably try going back a few kernel versions to see where the ethernet speed was OK or started faltering. The name of the module should be listed (from a shell) in /sys/class/net/<ETHERNET IF NAME>/device/uevent . If the kernel is at fault, possibly look at the source code and see if the developers/modifiers has an email address in the .c or .h files you could use to contact. I find most device problems in Armbian are related to .dtb files or firmware files. Having said that, have you tried ethtool under Armbian (assuming you get full speed when booted to android) and manually set the interface speed and duplex?

    I think gnthibault I've mentioned this before in forums but is it possible confusion may be occurring between duplicate partition labels? In fstab, you have LABEL=ROOTFS / and in uEnv.ini etc bootargs=root=LABEL=ROOTFS What I'm saying is the internal emmc flash and sdcard may have the same ROOTFS label. Perhaps take the sdcard and relabel the ROOT partition with tune2fs or get UUID= value from blkid (and changing boot files in /boot/ and /etc/fstab ?

    Have a look at this post regarding kernel build. You will have to locate the relevant commit in https://github.com/150balbes/Amlogic_s905-kernel to get the correct version of 4.18.7 kernel source. As well as cross compile, you can also compile natively and either binaries seem to execute for me. As an aside, I'm running 4.19.7-aml-s9xxx and config-4.19.7-aml-s9xxx has CONFIG_USB_SERIAL_FTDI_SIO=m and ftdi_sio.ko has already been built, if that's what you are looking for (assuming you have the correct .dbt which activates your USB ports).

    For anyone reading and this is not working, it may be the file /lib/firmware/brcm/nvram_ap6330.txt is missing. I'm using the same kernel on ubuntu but earlier image and it's not present on the image or repository package. The working file is 1522 bytes long, 82 lines fb5322048b8fa27d612a9f4dce1696cd md5sum with a head saying #AP6330_NVRAM_V1.0_20121130.

    I'm not an expert and have not backed up using ddbr but you might have to restore by hand with the dd command - see /usr/bin/ddbr_restore_nand assuming you can boot any linux like O/S from SD card. I can see problems booting from SD card with armbian installed on emmc due to the root=LABEL=ROOTFS conflicts at boot.

    This forum post will help you with wifi as it looks the exact comms hardware at issue It may be that the dbt file could be the problem for ethernet, even when the appropriate one is being used.

    The 800Mb includes (sic) the header files and the rest of the kernel source. You can use this to compile what ever additional modules (driver) you wish so place it in the location where the driver source is looking for it.
