Cant Flash IP onto OAK-FFC-4P-POE

justin-larking

I'm attempting to set a static IP on the Oak-ff-4p-poe via the poe_set_ip.py script in depthai-python. The script is failing however citing "Flashing failed: Failure verifying while comparing configuration"

This is my output from bootloader_version.py:

Found device with name: 169.254.1.222

Version: 0.0.22

NETWORK Bootloader, is User Bootloader: False

Memory 'Memory.FLASH' size: 33554432, info: JEDEC ID: C2 25 39

Memory 'EMMC' not available...

This is the output of bootloader_config.py:

Found device with name: 169.254.1.222

Current flashed configuration

Error accessing config: Configuration data checksum doesn't match

Any idea whats going on here?

Hi justin-larking ,
Perhaps you could first try to factory reset the device? This usually resolves such issues.

justin-larking

Factory reset with the device_manager.py script in depthai-python. It reports "Error: Flashing Failed", device now appears soft bricked as its not discover-able anymore.

I guess I have to factory reset via usb-c?

Hi justin-larking ,
Yes, I believe that would be required. I'd also suggest using latest depthai version to get latest bootloader version (0.26).

I have managed to ;put the latest bootloader on via usb, with the latest bootloader is is discoverable over POE. However factory resetting still fails to complete. In addition I still cant flash a static ip it states "Flashing failed: Failure verifying while comparing configuration" still.

Doesnt seem to have a bootloader on it? This is while connecting via usb.

So running through the process; Above the screenshot was connecting via usb-c. WIth a usb-c connecting (and the dip switches set to 0x16) I factory reset the device:

It responds with:

Reconnecting and flashing with newest bootloader works:

Reconnecting via poe (dip switch set to 0x3), I can see an upto date bottloader.

However flashing a config onto the device still does not work.

What is going on here? How do I get config flashing/factory resetting to work? All of this is taken from the device_manager.py script in /utilities under depthai-python.

Could be related to IMU firmware improperly flashed, and IMU interfering on the bus (SPI, shared with NOR flash).

Try reflashing IMU from depthai-python:
python3 examples/IMU/imu_firmware_update.py

Would be useful to note down the type & version printed initially when starting the above script, then check again after flashing, either with the same script (but don't confirm to flash), or:
python3 examples/IMU/imu_version.py
