Description

I can get through to step 7. The volume mounts but when I try to write the image, I got a USB error. I've tried both Raspberry Pi Imager and Balena Etcher.

I have the jumpers 3 RPIBOOT and 4 USBOTG and the USB/UART switch set to USB.

Research direction

Start by reproducing the failure at step 7 on an E3EZ Manta board with the listed jumper and USB/UART switch settings, using Raspberry Pi Imager and Balena Etcher. The report names no repository files or tests; done means the image can be written to the mounted eMMC without the reported USB error.
