USB PD library gets stuck in loop waiting for VBus to be 0V when a USB-C charger plugged

Hi there,We have a custom board with STM32F030CC and PTN5110 chip as the TCPC. We are using the x-cube-usb-pd library with config USBPD_TCPM_LIB_PD3_CONFIG_1.Initially, DRP role is selected. When we plug in a standard USB-C charger (5V 3A output) to ...

Whats the relation between FatFs middleware (ff and the low layer implementation) and sd_diskio?

To my knowledge, FatFs requires some low layer drivers in orden to work, and those APIs must be provided by the user. In UM1721 is pretty well described: "The FatFs Middleware solution provides low level disk I/O drivers for some supported disk drive...
