Native UART communication

I wanted to enable native uart communication on the odrive board. I can configure the uart protocol as native in the tup configfile. Then the Tupfile.lua parses the config and compiles with the UART_PROTOCOL_NATIVE flag. However, this flag is never used on the current master branch, so setting it does not do anything. Why is that? How can I enable it? Or is it not supported anymore?

Any help is appreciated, thanks!

Bump on this, I’m running into the same issue of wanting to use the native protocol over UART to fully switch off of USB. Is this feature on the future roadmap?
