Hi,
we using the STM32MP157 custom board in this we are developing the bare metal drivers for the all the peripherals. Now we are able to send and receive the character on UART4 perfectly. But when we are configuring for the interrupt mode it's only forwarding the Rx event till GICD (pending state). But i had seen the Linux drivers for the UART4 in that wakeup event is activated i think this may be the issue. To activate wakeup event in the UART4 we need to enable the EVENT30. To enable the event30 what is the procedure. please let us know.
