Hello Jock.

 

I will buy an rk3328 dev board, IoT3288A, https://usermanual.wiki/Smart-Device-Technology/IOT-3288A/html. It could run Android 5.1.1 I. plan to run Armbian on this board. Could this board run your Armbian build? Could it be a bad idea to buy this board?

No idea, it may work or may not work, surely some hardware will differ and this may cause major or minor issues. You should ask the vendor/manufacturer for software support.

Announce:

 

Hello, I want to announce that Community Supported Configuration (CSC) board images are now built again by Armbian servers on a weekly basis!

This means that you can now download images for CSC boards (including xt-q8l-v10) browsing from https://github.com/armbian/community

 

Images are built from trunk, GPG-signed and SHA-sum is provided.

 

Feel free to donate if you find this useful and wish to offer support to the Armbian developers and maintainers.

 

Enjoy!

Hi Jock,

 

I have a Hannspree AK01 Mini PC with RK3288. It seems to be identical to the Rikomagic MK902II.
 

Yes, I should have read through the entire thread before, but it's too late now.


I went through the first tutorial:

Multitool
and
Armbian_22.05.0-trunk_Xt-q8l-v10_bullseye_current_5.15.35_minimal.img.xz

  • Multitool booted
  • Backup of the original firmware
  • Flash written with Armbian.
  • Reboot (did not happen, box does not respond)
  • Power off and power on.
  • Picture stays black, monitor goes into standby

Have I bricked the box? 😞

Can I possibly still access the box via USB2Go? It doesn't have a micro USB port, but I just ordered a USB A to USB A cable.

Or is a rescue only possible via UART?

Thanks in advance
Regards
Mierscheid

@Mierscheid sorry for the late reply, but I didn't notice the post.

 

The image you installed is for another board called xt-q8l-v10, which is based on rk3288 but surely not the same board.

This is quite important, because each board, especially "high-end" boards like this, have their own design and usually have a different Power Management Integrated Chip (PMIC).

This is important because this little chip drives all the currents of the board, and if it is not configured right won't allow the board to work the right way.

 

There may be other differences that may break things, so it is not advisable in general to burn an image directly on the eMMC without carefully testing it via sdcard first.

The board can surely be restored to working state, but without UART logs is impossible to even guess where is the problem; surely bringing the board into maskrom mode (see this post) will allow you to use rkdeveloptool to erase internal flash and force the board to boot from sdcard (either multitool or directly an armbian image).

 

I guess you already tried to boot the multitool from sdcard without success, this makes me think that the u-boot installed on eMMC has issues or does not even boot, which is bad enough to guess you need to bring the board into maskrom mode and do a manual intervention.

 

The maskrom mode link I posted above is for rk322x, but actually it works exactly the same because eMMC chips have all the same pin layout. Once you keep the short the emmc clock pin to ground, you are "clock gating" the emmc and in practice it excludes it from the system just like there is no eMMC at all. When you unshort the pins, the eMMC will start working again.
