the libi2c initialize calls rtems_io_register_driver, which requires `CONFIGURE_MAXIMUM_DRIVERS` defined from the application. In some BSPs, like mvme3100, libi2c is initialized at sysinit, causing the application to crash without the define. Adding this confdefs macro allows the user to add the libi2c if it is needed by the app, or omit it without crashing the system. In its current state, libi2c requires the BSP to handle registering the buses and drivers after initialization, the interrupt can be handled by the BSP I2C handler. > -- > embedded brains GmbH > Herr Sebastian HUBER > Dornierstr. 4 > 82178 Puchheim > Germany > email: sebastian.hu...@embedded-brains.de > phone: +49-89-18 94 741 - 16 > fax: +49-89-18 94 741 - 08 > > Registergericht: Amtsgericht München > Registernummer: HRB 157899 > Vertretungsberechtigte Geschäftsführer: Peter Rasmussen, Thomas Dörfler > Unsere Datenschutzerklärung finden Sie hier: > https://embedded-brains.de/datenschutzerklaerung/ _______________________________________________ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
