Hi,
I got myself a new Zero 3w with 1GB of RAM and NO eMMC.
I installed the OS to my liking ,OpenWRT, according to the guide to an SD card but the system does not boot as expected.
To make things a bit shorter, I tried 4 OS’s which should be supported by the device but I don’t get any output on my HDMI nor do I get any logs written.
Therefore i would state that either the device is broken or the firmware is defect.
To analyze that topic further I poked around with the rkdeveloptool on linux.
When no SD card is present, the device boots to Maskrom mode as expected.
- ld -> DevNo=1 Vid=0x2207,Pid=0x350a,LocationID=101 Maskrom
- td -> Test Device OK.
If I insert the SD card after the device started into Maskrom mode and then run the Flash Info command, i get the info about the SD card size.
I also went ahead and found the rkbin project on the radxa git.
There looks like to be an check upgrade script which has a way newer loader version within the development branch but I could not yet to make it work.
Anyone any idea? Please?
Best Regards,
Christian
