Hello,

we are currently in the process of integrating a USB 3.0 camera (goal = 1920x1080@30fps) into our system, which is powered by a PicoCoreMX8MM.
As the i.MX8MM does not have native USB 3.0, we use the uDP720202 PCIe to USB 3.0 chip. So far so good,…

As you can see, the converter gets initialized correctly and…

Thanks for the reply.
I was hoping this wouldn’t interfere with I2C, but looks like I’ll have to take it into account after all.

Hi F&S support team,

we have ordered a evaluation kit PicoCore™MX8MM Linux (V14I). Currently the display is not running and I´m wondering why.
I missed to check the installed state when I received it, because I build a custom rootfs with Buildroot and…

Hi Saturnion ,

In general, I would recommend removing the PS (Push-Up Enable) and PE (Push/Pull Enable) flags for I2C.
Provided you have external pull-ups on the I2C lines, it should be fine to use only ODE (open-drain enable) for I2C.
