I am not able to access Ulogs on the Voxl Flight.

I inserted an SD card into the slot on the bottom of the board.
I set SDLOG_MODE from boot til shutdown
SDLOG_PROFILE is set to Default, Debug, and Computer Vision and Avoidance.

Still, no logs are loaded when trying to access through QGC. 

Is there anything I am missing?

Thank you

Hi @wilkinsaf ,

On VOXL Flight there are two SD card slots actually, can you verify you are using the one at the "pointy" end?

Although the following link is Flight Core, it can be used as reference since that portion of VOXL Flight is the same:

There's a 32GB size limit as well for PX4 (perhaps Nuttx limit, the RTOS under PX4)

I think I mistakenly thought this was some kind of chip

Let me stick the SD card in there and find out.

Yeah, that did it. 

Apologize for the rookie question. I have limited access to the board as it is already places in a body. So finding that slot was a pain. Thank you  @modaltb !

No problem at all, I'll get our docs updated so it's more clear, definitely not a rookie mistake, we should call it out!
