Based on this [On-Device Programming documentation](https://docs.luxonis.com/software/depthai/on-device-programming) page, Luxonis customers are not expected to manage or update firmware versions on devices. 1. Am I reading this correctly? 2. Is there any information you can provide about firmware versions as it relates to OAK-1 variants? 3. Which version is expected to be the latest for each variant and how would we update the OAK-1 when using depthai-core C++? For added context, some customers are getting frozen camera issues and I'm trying to determine if it is my software implementation or the OAK-1s. I see this [Crash Report](https://docs.luxonis.com/software/depthai/examples/crash_report) page, so I'll implement that at the very least.

luxd Am I reading this correctly?

Yep.

FW is coupled with depthai version so users don't need to worry about it. FW is the same on all variants.

jakaskerl Awesome, thank you for confirming!

So if there is a firmware update across versions, I'm assuming the internals of depthai-core do the flashing to update? Is there any way to see the firmware version history or otherwise get an idea of how often firmware is updated across versions? For example is there a firmware update each version or is it rare?

More specifically, how many FW updates are there between v2.24.0 and v2.29.0?

FW updates are more common than depthai versions since there are many small bugfixes/new features that are being deployed constantly. No flashing is done, the depthai device binary is uploaded each time you start a pipeline so the firmware is basically sent to the device without the need for flashing.

luxd More specifically, how many FW updates are there between v2.24.0 and v2.29.0?

A lot. Each time the FW commit is updated like here: luxonis/depthai-coreacafbab

jakaskerl So does that mean all OAK-1 installs have the latest firmware (once pipeline initialized) even if they're on an older depthai-core version like v2.24.0? Or are FW updates gated by the corresponding depthai-core version?

FW updates are gated by the corresponding depthai-core version.
