I2C Set Speed

wolftec · October 2023

I have an application were i need to use 100khz mode on the I2C

I've used CRB Settings to change all the I2c Buses i could find on the Bios to Standard Mode, it always runs on 400Khz mode.

I've got a I2c device on I2C1 (on Pin 3, 5).

Upboard Squared V2
Bios: USEHAM13
Ubuntu 20.04 with Upboard Kernel 5.4.0 and pinctrl-upboard_1.1.3

I've looked to the signals with a logic analyser

Thanks for your help
