We have developed a custom board using STM32MP157AD3 chipset and STPMIC. We did develop a dts using CubeMX and did all the patches as mentioned in Lab documentation. But we came accross 2 errors.

When we use the PMIC values from DK2 example.1 . ERROR:  regul ldo3: max value 750 is invalidWARNING: register_pmic:600 failed to register ldo3PANIC at PC : 0x2fff05cb2 Next we tried setting the ldo3 max, min values to 3V and 1.8V and it was working ...

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...

STM32MP153 MCU wakeup MPU via IPCC interrupt

Hi all,   I work on a STM32MP153 device and I used the command echo mem > /sys/power/state to put CPU A7 in Cstop mode, but I still have MCU running.I am wondering if a message via IPCC from MCU to MPU (that is stopped at WFI) can wakeup the A7 CPU.I...
