Zero D4E64H unable to detect eMMC on PC and more!

I’ve followed the guides and used RZ_USB_Boot_Helper + radxa-zero-erase-emmc.bin to erase the onboard eMMC and it does get detected by windows as a GX-CHIP in device manager under libusb-win32 devices.

You should load radxa-zero-erase-emmc.bin when the device is detected as GX-CHIP, then after a few seconds it should turn into a USB storage device by itself for Etcher.

I’m trying to get radxa-zero-debian-buster-xfce4-arm64-220220616-0314-mbr.img to be written to the onboard eMMC

Please try with the latest image.

On a side note, the device doesn’t boot up in any form when powered separately from a USB C cable with an adequate Power Adapter, no output from HDMI. The Green LED doesn’t turn on when powered by non PC connection methods, and when plugged into my PC its a steady green LED that turns on.

Radxa Zero Ubuntu 20.04 won't boot with HDMI connnected

This is likely due to difference in ground level between your HDMI device and your board power supply. You can try using a different power supply, or ideally, use the USB port on your monitor/TV to eliminate this issue.
