Hi Nvidia Team!

We’re using Jetson Nano with L4T 32.7.5. Is there support for multi-master I2C?

According to the information on that L4T 32.7.5, it does claim to have support for Jetson Nano (https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3275/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/software_features_jetson_nano.html#).

If there is support for multi-master I2C… does it work correctly or is there some kind of issue (as there seems to be with Jetson TX2)?

Thank you!

The driver i2c-tegra.c did support it but didn’t verify on Jetson system.

Thanks

Thanks for your reply!

I understand what you’re saying, but since it’s not verified on Jetson system, I’m still not sure if it works on the Jetson Nano or not…

Does anyone know if I2C multimaster works on the Jetson Nano?

Thank you very much!
Dani.
