USB comm with 2 rt685 evks with zephyr

[skanda19]

Hello, 

I am trying to create a "umbilical" communication path between 2 rt685 evks using zephyr. There's a couple examples in the zephyr SDK, specifically the CDC ACM example, the evk can echo data back to a terminal. 

I was thinking,  I might be able to leverage this example with some tweaks to to interface with another rt685 board, but I am pretty green on both USB (2.0 to be specific) and zephyr. Mainly I wanted to get some guidance to know if this is a good path to take or if there's a better way to start. 

thanks!

Hi @skanda19 ,

Thanks for your interest in NXP MIMXRT series!

It may be that your local git repository has not been updated yet, so it only contains device examples and not host examples.

You can refer to this link:https://github.com/zephyrproject-rtos/zephyr/tree/v4.1.0-rc3/subsys/usb/host

Best regards,
Gavin
