[BUG] Documentation for getting started with OAK-FFC-6P

[patrickwasp]

Describe the bug Cannot connect to OAK-FFC-6P using demo apps or scripts

Minimal Reproducible Example

1. plugged in a mono camera into the CAMA port
2. connected a USBC 3 cable to my Intel PC running Ubuntu 22.40. PG (power good?) LED lights up so I assume I don't actually need to use the barrel power jack.
3. ran sudo wget -qO- https://docs.luxonis.com/install_depthai.sh | bash, "No DespthAI device found!"
4. lsusb shows a new device: Bus 004 Device 093: ID 0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget
5. downloaded https://github.com/luxonis/depthai-python
6. ran python3 depthai-python/utilities/device_manager.py, "No devices found."

Additional context

• Plugged in a 5V center positive barrel jack to see if that would help, but same issue.
• Pressed Reset buttons and power buttons
• LED1 and LED2 stay unlit.
• The heatsink is getting warm.

Am I supposed to upload firmware to the board before using it? Do I need something on the microSD card?

A step-by-step guide on bringing up a module to a working state is needed.

@patrickwasp Sorry for delay

To work with RVC3 devices via DepthAI - use rvc3_support or rvc3_develop branches.
