I have troubles in setting the polarity of the SPI chip select i/o for an external chip.I noticed In the reference manual that it should be changeable with SPI configuration register 2 (SSIOP bit 28) :Bit 28 SSIOP: SS input/output polarity0: low leve...
I would like to provide power from PI connector. How to avoid error blocking message at the start of the boot that report:************************************************ ERROR USB TYPE-C connection in unattached mode ** Check that USB TYPE-C cabl...
Dear all,We are designing a board using STM32MP1 and STPMIC1 mostly as recommended in datasheet and application note. As we have a wide VIN range we added a discrete DC/DC with a 5V output that supply STPMIC1 VIN.We would like to use STMPIC1 PWR_USB_...
Dear All,We are designing a custom board based on STM32MP1. In some ST documents we can read "if no external battery is used, it is mandatory to connect this pin [VBAT] to VDD." If I check the developpement board schematic VBAT is simply connected to...
