Hello,
I recently received a Pinetab2, and I'm very pleased with the quality of manufacture. However, I wanted to try using Ubuntu touch or Mobian instead of Danctnix. I flashed the Ubuntu touch image listed on the releases page onto an SD card, plugged the SD card into the tablet, and turned it on. Every time I tried booting, it booted Danctnix. When I plugged the UART adaptor into the bottom USB C port and turned the switch to the "on" position, nothing at all booted. The same thing happened when I tried booting Mobian.
I tethered the tablet to a phone and updated the Danctnix system, because I saw that on the most recent factory image, Mobian could supposedly boot without using the UART adapter. Nothing changed.
I followed the instructions on this page to install Mobian. I installed U-boot, but I didn't see any change in behavior. According to the "About this System" page, the the version of U-Boot is 2023.07.02-00055-gc294612d38 and the kernel version is 6.4.3-danctnix1-1-pinetab2.
Does anyone have any suggestions?

Hi,
Check Pinetab2: (multi)boot normal image on eMMC and some OS on SD- card, #3. To boot the SD card, it needs 2 partitions in a specific way. I didn't try other OSes yet but this might be the way ...

Thank you for the advice,
I tried following your procedure on the linked thread. I found the "osimage.img" file and wrote that to my SD card. It formed four volumes: one 32 mb volume of free space, one boot partition, one OS partition, and then another 9.7 GB volume of free space. I tried booting again, but it only booted from the eMMC. I'm not very familiar with this, so it might be a dumb question, but could the bootloader not be recognising the SD card because the card starts with a partition of blank space?
I also tested mounting the SD card on the tablet, so I know that it isn't a hardware problem.
I think your SD isn't booting bc you've grabbed and are trying to boot Ubunut Touch for the first PineTab. original PineTab imgs will not boot on the PineTab2.
All of the images that I downloaded were from the websites linked on the "Releases" part of the Pinetab2 wiki, and all the files had "pinetab2" in the file name, so I Don't think they can be the wrong images.
Have you checked the minicom or screen output while the card is booting?
https://wiki.pine64.org/wiki/PineTab2#Co...RT_adapter
Okay, I've recorded the output while the Pinetab2 was booting. I don't really know what I'm looking at, so I've included all the output up to the login. Most of it will probably be useless.

Hi,
Meaning of some log lines ...
>> "Trying to boot from SPI"
Your boot process starts on the SPI flash (which is ok ° but needs configuration)
>> "INFO: Preloader serial: 2"
"U-Boot 2023.07.02-00055-gc294612d38"
There is a U-boot preloader on it

There are 3 slots for MMCs: fe310000 = internal MMC, fe2b0000 = SD card slot
fe2c0000 slot not made operational on the Pintab2 board ? (Card did not respond to voltage select! : -110)

You can stop the boot process here and work with the preloader (has useful U-Boot commands, type help to get list)
>> "** Booting bootflow 'mmc@fe310000.bootdev.part_1' with script"
Boot process is now passed to the internal MMC
Is U-boot on the SPI configured to boot from your SD card ? Right boot order ?
Is there a bootable partition on the SD card ?
>> "Starting kernel ..."
There is a working kernel on the internal MMC
>> "/dev/mmcblk1p2: recovering journal"
The system on the internal MMC was damaged
>> "Welcome to Arch Linux ARM!"
Damage is solved, Arch Linux starting
° INFO
When unmodified, Pinetab2 starts the boot process on the internal eMMC (as SPI flash is not configured ?). An initial boot script (boot.txt) on the internal eMMC checks for the presence of a SDcard. If this one is correctly partitioned, it will boot the 2nd partition on the SD card. Since you installed U-Boot to the SPI, it's this boot environment that has to be configured to check the SD card if it's bootable (doesn't need to be the second partition, I presume).
