UART & I2C implementation in Userspace program

ashoksowndar — Fri, 07 Feb 2020 07:57:05 GMT

Hi,

I am using i.MX 8M based SOM for my development and build the working image for it using Yocto. Now I want to use general purpose UART & I2C to communicate with external device using a C program written in userspace.

Can you please help me with this?

Thanks and Regards,

Ashok

Hi igorpadykov,

The Linux documentation that you have referred are related to kernel and low-level driver configuration.

But I am expecting some way to communicate with peripherals connected through UART or I2C interface using a userspace program(C language based program).

Thanks in Advance!

Regards,

Ashok

Hi Ashok

such userspace program(C language based program) can be written using

standard Linux APIs as described in suggested documentation.
