I'm still not happy with that. What I had in mind was more or less: static void output_char_serial(char c) { arm_pl011_write_polled(&pl011_context.base, c); } static void output_char_fb(char c) { fbcons_write_polled(&fb_context.base, c); } BSP_output_char_function_type BSP_output_char = output_char_serial; And if you decide that the frame buffer should be used in the select function you do a BSP_output_char = output_char_fb; > > BSP_output_char_function_type BSP_output_char = output_char; > diff --git a/bsps/arm/raspberrypi/console/console_select.c > b/bsps/arm/raspberrypi/console/console_select.c > index bd246ca868..ea3325266f 100644 > --- a/bsps/arm/raspberrypi/console/console_select.c > +++ b/bsps/arm/raspberrypi/console/console_select.c > @@ -15,69 +15,40 @@ > * http://www.rtems.org/license/LICENSE > * > */ > - > #include <bsp.h> > +#include <bsp/raspberrypi.h> > +#include <bsp/arm-pl011.h> > +#include <bsp/fbcons.h> > +#include <bsp/rpi-fb.h> > #include <bsp/fatal.h> > +#include <bsp/console-termios.h> > + > #include <rtems/libio.h> > #include <stdlib.h> > #include <string.h> > #include <assert.h> > #include <termios.h> > > -#include <rtems/termiostypes.h> > #include <libchip/serial.h> > -#include "../../shared/dev/serial/legacy-console.h" > -#include <bsp/rpi-fb.h> > > -rtems_device_minor_number BSPPrintkPort = 0; > +int console_select = PL011; > +console console_instance = arm_pl011_write_polled; > > -/* > - * Method to return true if the device associated with the > - * minor number probs available. > - */ > -static bool bsp_Is_Available( rtems_device_minor_number minor ) > +static bool bsp_Is_Available( int index ) > { > - console_tbl *cptr = Console_Port_Tbl[ minor ]; > - > + const console_device *dev = &console_device_table[index]; > + rtems_termios_device_context *con = dev->context; > /* > * First perform the configuration dependent probe, then the > * device dependent probe > */ > - if ( ( !cptr->deviceProbe || cptr->deviceProbe( minor ) ) && > - cptr->pDeviceFns->deviceProbe( minor ) ) { > + if ( ( !dev->probe || dev->probe( con ) ) ){ > return true; > } > > return false; > } > > -/* > - * Method to return the first available device. > - */ > -static rtems_device_minor_number bsp_First_Available_Device( void ) > -{ > - rtems_device_minor_number minor; > - > - for ( minor = 0; minor < Console_Port_Count; minor++ ) { > - console_tbl *cptr = Console_Port_Tbl[ minor ]; > - > - /* > - * First perform the configuration dependent probe, then the > - * device dependent probe > - */ > - > - if ( ( !cptr->deviceProbe || cptr->deviceProbe( minor ) ) && > - cptr->pDeviceFns->deviceProbe( minor ) ) { > - return minor; > - } > - } > - > - /* > - * Error No devices were found.
