Flashing OpenHarmony on RK3568

ROCK 3 Series
1

Hi,
I’m working with Rock 3A board with SD Card and no eMMC device.
I’m trying to burn OpenHarmony 4.1 (OpenHarmony-v4.1-release -> RK3568 standard system solution (binary)) binaries to target.
I’ve downloaded linux flash driver.
flash.x86_64 LD shows that device is present and visible.
However - attempts to flash above mentioned img failed.
./flash.py -i ~/Downloads/OpenHarmony_img -a
Application writes that all is successful - but after power reset, device doesn’t start.
Now it started complaining with

/home/sebastian/Downloads/OpenHarmony_img/driver/bin/flash.x86_64 UL /home/sebastian/Downloads/OpenHarmony_img/MiniLoaderAll.bin
Program Data in /home/sebastian/.config/upgrade_tool
Loading loader...
Loading loader failed,err=-1!

ROCK 3A doesn’t support OHOS at the moment, if you need to burn RK3568 standard program image, some functions may not work properly.

See if your compiled image list has files like “MiniLoaderAll.bin/parameter.txt”, if it does, you can use the rkdeveloptool tool to burn it.

Yes, image list contain MiniLoaderAll.bin and parameters.txt.
Where can I find list of commands or/and images addresses where to upload those images? I could do so following parameters CMDLINE. But I seen that MiniLoaderAll/paramters require additional/different approach (from RKDevTool Windows pictures). rkdeveloptool db MiniLoaderAll.bin works and puts device in maskrom.
But … how to do it all onto SD drive?

Oh, sorry, just noticed you don’t have eMMC, this method may not work for SD Card.
