Up Board (Not UP2) I2C can not be set at 100KHz
I changed the speed of my I2C (I2C-5 or hardware I2C-1) in the bios from 400 KHz to 100 KHz and changed the mode from ACPI to PCI. I still have my I2C at 400 KHz when I probe. I tested it with 4 Up Board. It worked only for one of them. Can anyone help me?
