STM32MP135F custom project with no I2C bus

[JVan.1529]

Hello.

 

I am trying to get a custom design using STM32MP135F to boot.

Unlike the DK, it does not use I2C busses, and I2C is not listed in the DTS files as created by STM32CubeMX.

I follow the wiki "How to compile the device tree with developer package" .

When I run the make command, I get error messages:

i2c4_pins_a  not found

also errors about sdmmc2 pins, which is also not used nor mentioned in the dts.

Is there somewhere a dts coupling that I am missing?

Thanks for helping.

Jan

Hi @JVan.1529 

 

You have to carefully setup your dts.
