I'm trying to understand how I can use a USB Type-C connector together with the STM32MP1 USB OTG peripheral.So obviously I want to use the port in dual role configuration. I want to use the STUSB1600 for that because it takes care of the power source...

I would like to clear up some confusion regarding the DSI VIO, the stm32mp157a datasheet mentions "1.2 V I/O for DSI interface" but in the EV1 kit the LCD used (the RK055AHD042-CT, for which it's impossible to find a datasheet for, could that be shar...

I see, I was wondering how does the kernel know which role the peripheral should be used in if there is no ID pin but I think I understand now, I looked at the documentation for the chip in the kernel https://github.com/STMicroelectronics/linux/blob/...

To add to the confusion, I noticed in CubeMX there are 2 options for setting up the OTG peripheral and the one that says "Type C" disables the ID pin :persevering_face:

Thank you, that seems reasonable As my profile mentions, I am a hobbyist so the LCD I want to use is a Blackberry Q5 LCD (marking LCD–49754-000) obtained from China as a replacement, the datasheet is not officially public, although it is possible to...

Thank you for the exhaustive explanation Patrick, but I'm still a but unsure if that means that my LCD can be used with the STM32MP1, since like you mention the 1.2V voltage and my LCD's datasheet mentions 1.8V:As for the data lanes, the LCD uses 2 a...
