TV Box S912 (X9T 4K): problem to install on emmc

[Nico059]

Dear All,

 

First I would like to thanks all the contributors to armbian, What a great OS for our small SBC !

 

Context:
I run succesfully latest Armbian on a X9T 4K TV Box (amlogic s912) from SD Card 2GB (following instructions here  

 

The Problem:
I would like to run armbian from emmc (16GB on this box) for better reliability and performance.

So, I run the install-aml.sh script, I had some error (no boot.ini ...), but the process seems to finish successfully

 

Next Reboot:

It's seems my boot partition is Not OK ... something missing ...

 

 

For reference

See bellow for reference the succesfull boot from the sdcard

 

If I boot from SDCard,

I can inspect the /boot  and root partition on emmc,  everything seems ok

On the emmc partition, the  /boot/extlinux/extlinux.conf is correctly modified:
 

extlinux.conf
LABEL Armbian
LINUX /Image
INITRD /uInitrd

#FDT /dtb/amlogic/meson-gxbb-p200.dtb
#FDT /dtb/amlogic/meson-gxl-s905x-p212.dtb
#FDT /dtb/amlogic/meson-gxl-s905w-tx3-mini.dtb

#FDT /dtb/amlogic/meson-g12a-x96-max.dtb
#FDT /dtb/amlogic/meson-g12b-odroid-n2.dtb

  append root=LABEL=ROOT_EMMC rootflags=data=writeback console=ttyAML0,115200n8 console=tty0 rw no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 splash plymouth.ignore-serial-consoles

 

And the disk partion on the emmc

fdisk -l /dev/mmcblk1

 

Disk /dev/mmcblk1: 14.64 GiB, 15724445696 bytes, 30711808 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x09170000

Device         Boot   Start      End  Sectors  Size Id Type
/dev/mmcblk1p1      1953792  2953215   999424  488M  c W95 FAT32 (LBA)
/dev/mmcblk1p2      2955264 30711807 27756544 13.2G 83 Linux

 

If you can help me ....

Thx in advance

Nico

better readability of my problem ;-), and add fdidk -l of emmc

Some other informations:

I have been able to interrupt the uboot process (when box start without SDCARD), and try some command (see capture):

mmc list, and mmc info  : the dev 1 is the eMMC, so it's recognized

mmc part, partition table unknown (don't know if it's ok or not...

 

And when I boot from SDCard (fresh Armbian); here is the lsblk result:

-mmcblk0 is the SDCARD (2GB)

- mmcblk1 is the eMMC (16GB) with all supposed partitions ....

  - mmcblk1p1 (the /boot)  : I can mount them and the content seems ok

 - mmcblk1p2 (the  root: /) : I can mount them and the content seems ok

- mmcblk1boot0 and mmcblk1boot1, with 4 MB size, that is the uboot partitin if I understand correctly (the one that of backuped with dd if of durint install-aml.sh script)

 

 

@SteeMan, do you have any idea why this box refuse to boot from emmc.

I can do other investigations if you can help me 😉 (I learn lot's of stuff with this problem about u-boot and all : it's a good for a bad...)

Thx in advance,

Nico

on the sdcard, did you copy /boot/u-boot-s905x-s912 to /boot/u-boot.ext, before running install-aml.sh?

I think install-aml.sh will cause u-boot.ext to be copied to emmc /boot/u-boot.emmc - is that file there on emmc boot partition?

Hello how are you? I have exactly the same problem, when I ran armbian from SD it works perfectly but when I install in emmc with the script, it takes 15 minutes, it ends ok but when I turn off and remove the SD memory to boot from emmc the same thing happens to me, I put it again the SD and it works perfectly, I don't know what else to try, I tried with different versions of armbian, I tried to change the Android version so the boot changes and then I press it with armbian and there is no case, I would appreciate if someone knows something
