Jetson Xavier NX Carrier Board MCU firmeware

Hi, Is the source to the MCU firmware on the Xavier NX carrier available somewhere?

I’m seeing from P3509_A01_OrCAD_schematic.pdf the MCU U18 model is EFM8S810F2G QFN20. There is also a state diagram about how the MCU should work. I’m wondering if we use this exact part in a custom design, whether we’ll need to implement the same logic or we can just load the available firmware.


The firmware is in DLC:

Thanks for the download link. Will give it a try. I saw on another question the customer could not program it.
