Hi,
I seem to have issues flashing Ubuntu to eMMC on Windows. Here’s how it went for me.
I started having a brand new Raxda Zero 8GB with Android. It booted to Android fine. I was able to install Zagdig USB device, as well as Android driver. I am able to see libusb-win32 device (GX-CHIP) in Device Manager.
-
I watch some YouTube video and started by downloading and sideloading factory-loader.img <— I think this is where I must hack whacked the bootloader
-
i read more and used radxa-zero-erase-emmc.bin, after which a USB device pops up, I have to format it with FAT32, and after that using balenEtcher I burn radxa-cm3-io-ubuntu-focal-server-arm64-20220315-1221-gpt.img to it. I turn off/on Raxda
-
Nothing happens in HDMI output, in serial I get:
G12A:BL:0253b8:61aa2d;FEAT:E0F83180:2000;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8; -
If i try to sideload u-boot.bin i get the following output

Starting kernel ...
But it stalls after it.
- i have also burned sdcard with the same image but that doesn’t start either.
I also have Python 3 installed as well as pyamlboot, and able to run boot-g12.py in case that’s needed.
i cannot see Raxda via adb.
Could you please help with flashing the eMMC with Ubuntu? Grateful in advance!
