JKris Posted September 20, 2021 Share Posted September 20, 2021 Hi Nexon, where should I change the status to what you mentioned? Can you please specify the filename to change? Thanks 0 Quote Link to comment Share on other sites More sharing options...
Kcc122 Posted September 6, 2022 Share Posted September 6, 2022 I'm also trying to get my i2c to work albeit on TB2S. What my research has led me to is instantiation of i2c and the new_device... Can anyone confirm the correct way too go about this without having to recompile a kernel, eg userspace? 0 Quote Link to comment Share on other sites More sharing options...
