Which dtb to choose for gtking-pro

[MX10-AC2N]

Hi, And first of all a big thank you for sharing. So I have a Beelink Gt-King Pro with a serial number starting with SA9H ... I managed to start the latest Bulleyes flash release on sd card using the gt-king-pro-rev_a.dtb but I had a system freeze and as we find a lot of different dtb with gtking-pro as a header suddenly I'm not sure I'm using the correct one .. Anyway when I use Coreelec on my gtking-pro I also use a dtb marked rev_a that's why I used this one . . Thank

meson-g12b-gtking-pro-rev_a.dtb for odroid-n2

You can use Armbian_21.11.0Amls922x_*.img to boot from a USB/TF card. Its default dtb file is meson-g12b-gtking-pro.dtb, and you can install it to EMMC and select 42. Choose meson-g12b-gtking-pro.dtb for your device.

[MX10-AC2N]

Thank @ophub, I had first tried with gtking-pro.dtb but had failed to start, I will try again .. I don't want to install Armbian on the Emmc but kept the system on SD card. I didn't understand what you can select 42 means. Thanks again for the info, I'll keep you posted on the progress.

[MX10-AC2N]

OK, I was able to boot with gtking-pro.dtb. I regularly have a freeze on restarting just when the USBs should start. I have to electrically unplug the Gt-King Pro and plug it back in for the startup to complete successfully. Are there a few things in particular that need to be done to boot from the sd card? Thanks again for sharing, before to run Armbian on my GT-King Pro I used an image built by Balbes150 but it was not really done for this tvbox, now thanks to you, we have some ... Thank you so much..

It is a good choice to use armbian on TF/SD/USB card, with larger space and more flexible use.

It is recommended that you use the armbian-tf command to activate the remaining space on the TF/SD/USB.

You can also use the armbian-swap 1 command to create virtual memory, so that the system has more sufficient operating support.

In daily situations, you can use the armbian-update command to update the kernel.

The system restart command is reboot

[MX10-AC2N]

Thank.. I used armbian-tf and I have a new partition with the remaining space of my sd-card 128G mounted on /mnt/mmcblklp3. But the partition / still at 2G, I prefer extend the partition /

[ophub]

Your idea is very good

[ophub]

You use a s922x gtking-pro box and a 128g SD card. You are the most beautiful boy in our village.

[MX10-AC2N]

Lol, I use armbian for install YUNoHost... https://github.com/YunoHost/yunohost

armbian-tf: According to your good wishes, you can now choose to create a new partition or expand the current partition.

According to the prompt, enter e to expand the remaining space to the current system partition and file system, and enter c to create a new third partition.

[MX10-AC2N]

Wow, congratulations @ophub You code faster than your shadow, you are the Lucky Luke of computer coding. I allow myself to add a little more, the best would be to be able to extend the main partition entirely or up to a chosen size and to create a new partition with the remaining space. Is there a way to undo my previous armbian-tf command or do I need to reflash my sd card .. Thank you again, and sorry for the formulations I am French and I use google translate for English

[ophub]

df -hT: View your partition name, such as/dev/sda

fdisk /dev/sda: Press m to view the parameter description, follow the prompts to select d, input 3 to delete 3 partitions, select w to save, and enter umount /dev/mnt/sda3 to uninstall

Overwrite the original local file /usr/sbin/armbian-tf with the new armbian-tf file, then chmod +x /usr/sbin/armbian-tf

Then armbian-tf select e extended partition

[MX10-AC2N]

I started again from zero, I reflashed a sd card but I again have this freeze problem at startup

[MX10-AC2N]

After having unplugged / re-plugged the box 3 times I was able to go to the next step but this time the startup was not completed correctly .. I will reflash my sd card again .. However I already had this problem of freeze at startup, could it be the fault of my sd card, which shows no error when I check it under windows10 ..

Which box ?

which kernel version of the firmware is used?

has it ever been written into emmc?

What system is currently in the emmc of the box?

[ophub]

There are always more solutions than difficulties, choose a solution you like:

1. The firmware using the 5.4 kernel does not require u-boot secondary boot, so this phenomenon will not occur.

2. This is a phenomenon that may only occur with kernels of 5.10 and above. At present, the boxes listed in the instructions on the homepage have all been adapted, and this phenomenon is gone. But the unknown box may appear this phenomenon due to the u-boot file mismatch.

3. By writing the 5.10 armbian firmware into emmc, replacing the Android u-boot of the box with the u-boot that comes with the customized firmware, the booting problem is solved.

4. Adding a resistor to TTL can solve the problem of using the kernel of version 5.10 and above. such as: Add resistor

Which box ? => It's again with my Beelink GT-King Pro

which kernel version of the firmware is used? => I use kernel 5.10.84

has it ever been written into emmc? =>No

What system is currently in the emmc of the box? => Android 9 from beelink

Thank again @ophub you're great..

[MX10-AC2N]

This morning I downloaded the latest version Armbian_21.11.0_Aml_s922x_bullseye_5.10.85_2021.12.15.1030.img.gz Flashed to my SD card Renamed the uboot-gtkingpro.bin file on the /boot partition to uboot.ext Checked /boot/uEnv.txt to use the correct .dtb file (it was already the correct one, so no modif in uEnv.txt) On my gtking-pro tvbox I only connected my wireless keyboard receiver to 1 of the USB ports. And I have the impression that depending on the USB port it's plugged into I'm going to have this freeze problem on startup, I'm going to do some reboot tests to verify this ..

[MX10-AC2N]

Well finally I had this freeze problem again at startup .. nothing to do with being plugged into a particular USB port .. I took a screenshot on a successful start. We can see errors .

[ophub]

You try the 5.4 kernel firmware.

[MX10-AC2N]

No, I haven't tried kernel 5.4 I prefer to try to keep 5.10 because I know it works on beelink gtking-pro, there is even a linux-5.14 which is available on the forum http://forum.bee-link.com/forum.php?mod=forumdisplay&fid=196&page=1 When the boot finishes well, the system seems fully operational just the problem probably related to u-boot.ext .. In the photo I posted to you this morning, we can see an error marking "bootfromsd" not defined. is this normal even though everything is installed on an SD card?

[ophub]

ok

[MX10-AC2N]

Hi @ophub, Today I try the kernel 5.4 firmware Armbian_21.11.0_Aml_s922x_bullseye_5.4.166_2021.12.17.1259.img.gz But finally I have the same problem of freeze at startup .. I managed to start by removing everything on the USB inputs, perhaps a beginning of response to this problem .. Finally I also believe that my concern is linked the fact that I keep the Beelink Android 9 firmware on the emmc is that suddenly there is a conflict between Uboot legacy and Uboot mainline. Is it possible to have an armbian construction planned to be installed on an external sd or usb support and especially planned so that we have kept Android on the emmc. With Android I can still see all the web content protected by DRM rights (netflix, amazon prime video, ..) while under armbian, in particular in arm64, this is not yet possible, one day maybe .. finally I ' hope .. I will try all this by installing on a USB medium for comparison .. Thank you again and sorry for this bad news, for the moment difficult to start under Beelink GTKing-Pro no matter which kernel was using ..

[MX10-AC2N]

I started again from zero, I reflashed a sd card but I again have this freeze problem at startup

Same freeze.

[MX10-AC2N]

I tried to flash to USB media to see if the problem was not with my sd card but I end up with the same freeze on startup .. It does not work correctly on my Beelinnk GTKing-Pro .. Sorry @ophub

[MX10-AC2N]

@ophub Oops, I'm sorry, I didn't configure the /boot partition correctly I had first done as on the other firmware, i.e. rename u-boot.gtking-pro.bin to u-boot.ext => That was my error there is no need to u-boot.ext so I rename it to u-boot-ext.bak and this time the boot goes smoothly .. Thanks and sorry again ..

[MX10-AC2N]

Beelink GtKing-Pro have 4Gb of RAM but with the firmware 5.4, system have only 3,24Gb and when I boot 5.10 the system have 3,7Gb Why we can't have the 4Gb of the tvbox ?

[MX10-AC2N]

Hi @ophub I finally got to boot kernel> 5.10 on my Beelink GT-King_pro but I didn't use your u-boot.ext but this one .. u-boot.zip I start with 5.10.88 , boot ok but with black screen, ssh access is ok "armbian-update 5.15.12" work fine and after the reboot my screen work correctly.. With this u-boot.ext I can boot but only with USB OTG.. Can't boot on other USB or SD-Card.. If that can help others . https://paste.yunohost.org/fuwubonube.vbs Big Thanks for all you do.. .
