Not sure about better, but simpler/cheaper could be a single 5-10k resistor in the "RTS" line after the transistor (where the "10k"/0 Ohms are now), with the other MCU's pin connected directly to GPIO0. This way, as long as the MCU outputs high, RTS cannot pull down GPIO0; tri...

Do you study idle_profile project? If yes, you should know it prints banner when power-on. If it wake-up LPDS and begin the code from where it left off, it prints wake-up source. For example: it prints GPIO when wake-up source is GPIO. ...
The firmware right now is just few GPIO lines code as this is a co-processor to manage main power on/off with push button.. No other peripherals like USART/I2C/SPI are being used or interrupts enabled. No RTOS either. Just STM32CubeMX generated code for GPIOs compiled with...
