STM32MP135F-DK How to set LDO2

Hi, I have an STM32MP135F-DK board, and I want to set LDO2 and get an output voltage of 3.3V. I have read a document ( Integration of STM32MP13x MPU product lines and STPMIC1D / STPMIC1A on a wall adapter supply) which states that LDO2 must be set af...

STM32MP151CAA3T length matching

My question is what the recommended values are for STM32MP151CAA3T (see image for Altium xsignals creation for the routing).I am currently doing routing and I could not find all this information in the datasheet. 

Drive DSI data lanes to LP-11

Hello. I need to integrate a TI SN65DSI83 bridge with a DK2 board and one of the requirements of that bridge is to drive the data lanes to LP-11 state. What is the procedure to make that happen? I am assuming I need to make changes to dw-mipi-dsi / d...
