OAK-D-POE Flashing failed

xiaotang

I have an OAK-D-POE device, and now it won't boot as a network device, when I switch the boot switch to USB mode, it works, but it's not recognized in POE mode. I pulled the latest depthai-python code, tried to use device_manager.py to factory reset the device and reset the bootloader, but reported the following error
(venv) C:\code\depthai-python\utilities>python device_manager.py after connecting to device, <depthai.DeviceBootloader object at 0x000001EFABDA32B0> Exception in C:\code\depthai-python\utilities\device_manager.py, line 196; 'Progress' object has no attribute 'self' Exception in C:\code\depthai-python\utilities\device_manager.py, line 196; 'Progress' object has no attribute 'self' Exception in C:\code\depthai-python\utilities\device_manager.py, line 171; 'Progress' object has no attribute 'self' Traceback (most recent call last): File "C:\code\depthai-python\utilities\device_manager.py", line 639, in <module> app.run() File "C:\code\depthai-python\utilities\device_manager.py", line 448, in run self.window.Element('currBoot').update(self.bl.getVersion()) AttributeError: 'NoneType' object has no attribute 'getVersion
I also tried the flash_bootloader.py in examples/bootloader, also got the error

Hi xiaotang ,
We have just updated Device Manager (fix here), thanks for reporting! Could you try again with latest depthai-python (so git pull first)?
Thanks, Erik

I had this exact same error, and a quick google search led me to this thread. I tried the change you mentioned from 16 days ago, and got:
Exception in C:\depthai-python-main\utilities\device_manager.py, line 199; DeviceBootloader wasn't initialized to allow flashing bootloader. Set 'allowFlashingBootloader' in constructor

In order to get around this, I had to change line 226 to:
bl = dai.DeviceBootloader(device, True)

After that change, I was able to successfully reset to factory default and get my device working again.

Hi RichardWright ,
The newest main branch of the depthai-python repo should already have this fix; see commit here.
Thanks, Erik
