How can I use UART port on MKS Tinybee. Its UART2 connected on pin16 and pin17 of esp32. In FluidNC i have defined in config file and its working, but how can I do in grblhal?

Use for what purpose? In your own plugin?

Can i configure grblhal that it uses uart2 only.

Try adding #define SERIAL_STREAM 1 to my_machine.h.

Serial_stream 1 causes cpu fault

Attempted fix has now been committed. If this does not help more details are required.

Same problem

Try replacing this code with:

#ifdef DEBUGOUT
#define DEBUG_TEST 1
#else
#define DEBUG_TEST 0
#endif

#if (MODBUS_TEST + KEYPAD_TEST + MPG_TEST + TRINAMIC_TEST + DEBUG_TEST) > (SP0 + SP1 + SP2)
#error "Too many options that requires a serial port are enabled!"
#elif (MODBUS_TEST + KEYPAD_TEST + MPG_TEST + TRINAMIC_TEST + DEBUG_TEST) || SERIAL_STREAM == 1
#define SERIAL2_ENABLE 1
#else
#define SERIAL2_ENABLE 0
#endif

#undef SP0
#undef SP1
#undef SP2
#undef MODBUS_TEST
#undef KEYPAD_TEST
#undef MPG_TEST
#undef TRINAMIC_TEST
#undef DEBUG_TEST
