Hello We have the exact problem with an UART configuration. We have an entire batch of 6 boards that have been designed as-per the following schematic (see both datasheet, and actual schematic) that does not work. We provide a UART command using 115200 8N1, but the BNO055 COM0 pin (UART_RXD signal or P87 in our schematic) is always low. We have isolated that signal (cutting R361) to see if the MCU was driving it low, but both sides of the resistor read 0V even then. Can you provide any advice? Thank you
