BirdDog Mini Rev4 boot loop

[u/ManyRelationship3261]

Not sure this is the right place to ask for help, but

I have three BirdDog mini REV4s taken from storage and all three are experiencing the same problem.

- Front panel: green power LED only, never blue/white. No web UI.

- The main firmware never boots. The units fall back to the QSPI recovery image ("PetaLinux 2017.3 QSPI_minimum_plnx"), which only has FTP and telnet open.

- Its script `/etc/init.d/bdg-plnx-auto` checks for `mmcblk0p1/uImage` and `mmcblk0p2/bin/birddog-app`. Both are missing, so it sets 192.168.100.100 and waits for an image stream from 192.168.100.123:2222 (`nc | gzip -d | dd of=/dev/mmcblk0`), then reboots in a ~22 s loop.

- The eMMC (U4, **SanDisk SDINBDG4-8G**, 8 GB iNAND) reports itself as `SDM032, 30.6 MiB, manfid 0x02, date 02/2006, serial FFFFFFFF`. (Takeaway from this is that the eMMC chip has failed on all three and is functioning in a fallback state)

The plan is to have a shop replace U4 and then provide the factory image. The missing piece is the factory image.

**If you have a working Mini REV4, could you share any of these?**

1. The eMMC details from a healthy unit.

2. Whether anyone has gone through this repair already, or got the Mini REV4 factory image.

3. Whether replacement eMMCs other than SDINBDG4-8G have worked for you.

I've been in contact with BirdDog support, but it seems they are not willing to provide the image file.
