Hello. I have been struggling with my Pro PoE camera the last week, partly due to a broken PoE cable resulting in an unstable ethernet connection. Replacing the cable shows a stable 1Gb/s connection and I could connect to the cable without problems. However, some of the DepthAI examples revealed x-link timeout errors and I decided to factory reset the device. Running the device_manager.py and trying to factory reset the device apparently resulted in a bricked device, very much like reported on https://github.com/luxonis/depthai-python/issues/768 * DepthAI version: 2.23.0 * Bootloader version before factory reset attempt: 0.26 * Ubunty 20.04 * PoE injector: TL-POE150S * dmesg/ethtool show stable ethernet connection at 1 Gb/s * Wireshark shows no activity from the device on the NIC, no ping response and no response on arp-scan So what to do next? I've ordered a 8-pin male M8 connector and will be able to create a USB-bridge to the host computer. But will I be able to patch the Pro Poe bootloader from USB? Please advice. Regards, Per

OAK-D Pro PoE soft-bricked after factory reset, next step?

Hello.
I have been struggling with my Pro PoE camera the last week, partly due to a broken PoE cable resulting in an unstable ethernet connection. Replacing the cable shows a stable 1Gb/s connection and I could connect to the cable without problems. However, some of the DepthAI examples revealed x-link timeout errors and I decided to factory reset the device.

Running the device_manager.py and trying to factory reset the device apparently resulted in a bricked device, very much like reported on luxonis/depthai-python768

DepthAI version: 2.23.0
Bootloader version before factory reset attempt: 0.26
Ubunty 20.04
PoE injector: TL-POE150S
dmesg/ethtool show stable ethernet connection at 1 Gb/s
Wireshark shows no activity from the device on the NIC, no ping response and no response on arp-scan

So what to do next? I've ordered a 8-pin male M8 connector and will be able to create a USB-bridge to the host computer. But will I be able to patch the Pro Poe bootloader from USB? Please advice.

Hi @pshustad
Most problems can usually be solved by using the M8 adapter board and booting the device in recovery. The just flash the NETWORK bootloader to the device and it should return to its normal operation mode.

Thanks,

Thank you @jakaskerl , I soldered a home-made USB connector with the required connections ref https://docs.luxonis.com/projects/hardware/en/latest/pages/NG9097pro/#connectors. I left the AUX 3V3 open but still it worked out well. I then flashed the NETWORK bootloaded, and - no problem connecting over ethernet.

I guess the lessons learned are: Have a USB connector ready when trying to factory reset the device via PoE :-)
