If problems still persist, please make note of it in this bug report.

The decision to classify this bug as an AcceptedBlocker was made as it violates the following blocker criteria.

All release-blocking images must boot in their supported configurations for the release-blocking ARM minimal and Xfce disk images on Raspberry Pi 3, which is a supported ARM platform per.

I would advice updating to latest image (2020.04) and use the SD Card flash procedure precisely.

I suspect there must be an issue either while downloading the image or when flashing it with Etcher.

If you want another flashing tool, you can give this one a try.

EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode.

Im wondering if you dont have an issue with the card detection signal which.

In the case of sama5d3xplained, its on PE0 for mmcf0000000 and PE1 for mmcf8000000.
