The internal eMMC (/dev/mmcblk0 ) does not appear in ha hardware info or Move data disk .
The system only shows /dev/mmcblk1 (the SD card).”

Here’s what I have tried multiple times:
- Flashed a verified HAOS Green 16.3 image to a micro-SD card using Balena Etcher.
- Booted successfully and reached the Home Assistant CLI and web UI.
- Ran
ha os install /dev/mmcblk0several times — it completed without error, but the device still won’t boot without the SD card. - Checked in both the HA CLI and web UI (“Settings → System → Storage”) — the only visible disk is
/dev/mmcblk1(the 32 GB SD card). - The internal eMMC (
/dev/mmcblk0) never appears inha hardware infoor “Move Data Disk.” - Repeated installs with different SD cards and cables — same result.
- The Green works perfectly from SD, but once the SD is removed, it only shows a solid white LED and never boots.
Screenshots attached show ha hardware info output — only /dev/mmcblk1 (SH32G) is present.
Based on this, it appears that the internal eMMC module has failed or become disconnected.
Please advise on repair or replacement options.
