Hi,
Thanks for sharing.
But actually, I think your conclusion is not correct because the real issue you should resolve is why your board does not have /boot/dtb?
I just flashed my board with sdkmanager and there is /boot/dtb.
I tried the SDK manager flashing method for the b01 but it seems like the sd card flashed for one device is unable to be used for another (both b01). Is this known?
Also tried with such case and it can work. I guess this issue is also due to the missing of /boot/dtb on sdcard.
