The * canonically correct to implement such interactions is by implementing a * character driver and performing the interactions via low level ioctl * calls. This, however, may not be practical in many cases and will lead * to "correct" but awkward implementations. * * boardctl() is non-standard OS interface to alleviate the problem. It * basically circumvents the normal device driver ioctl interlace and allows * the application to perform direction IOCTL-like calls to the board-specific * logic. In it is especially useful for setting up board operational and * test configurations. * * Input Parameters: * cmd - Identifies the board command to be executed * arg - The argument that accompanies the command. The nature of the * argument is determined by the specific command. * * Returned Value: * On success zero (OK) is returned; -1 (ERROR) is returned on failure * with the errno variable to to indicate the nature of the failure. * ****************************************************************************/ int boardctl(unsigned int cmd, uintptr_t arg) { int ret; switch (cmd) { /* CMD: BOARDIOC_INIT * DESCRIPTION: Perform one-time application initialization. * ARG: None * CONFIGURATION: CONFIG_LIB_BOARDCTL * DEPENDENCIES: Board logic must provide board_app_initialization */ case BOARDIOC_INIT: { ret = board_app_initialize(); } break; #ifdef CONFIG_BOARDCTL_POWEROFF /* CMD: BOARDIOC_POWEROFF * DESCRIPTION: Power off the board * ARG: Integer value providing power off status information * CONFIGURATION: CONFIG_BOARDCTL_POWEROFF * DEPENDENCIES: Board logic must provide board_power_off */ case BOARDIOC_POWEROFF: { ret = board_power_off((int)arg); } break; #endif #ifdef CONFIG_BOARDCTL_RESET /* CMD: BOARDIOC_RESET * DESCRIPTION: Reset the board * ARG: Integer value providing power off status information * CONFIGURATION: CONFIG_BOARDCTL_RESET * DEPENDENCIES: Board logic must provide board_reset */ case BOARDIOC_RESET: { ret = board_reset((int)arg); } break; #endif #ifdef CONFIG_BOARDCTL_SYMTAB /* CMD: BOARDIOC_SYMTAB * DESCRIPTION: Select a symbol table * ARG: A pointer to an instance of struct boardioc_symtab_s * CONFIGURATION: CONFIG_BOARDCTL_SYMTAB * DEPENDENCIES: None */ case BOARDIOC_SYMTAB: { FAR const struct boardioc_symtab_s *symdesc = (FAR const struct boardioc_symtab_s *)arg; DEBUGASSERT(symdesc != NULL); exec_setsymtab(symdesc->symtab, symdesc->nsymbols); ret = OK; } break; #endif #ifdef CONFIG_BOARDCTL_TSCTEST /* CMD: BOARDIOC_TSCTEST_SETUP * DESCRIPTION: Touchscreen controller test configuration * ARG: Touch controller device minor number * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_TSCTEST * DEPENDENCIES: Board logic must provide board_tsc_setup() */ case BOARDIOC_TSCTEST_SETUP: { ret = board_tsc_setup((int)arg); } break; /* CMD: BOARDIOC_TSCTEST_TEARDOWN * DESCRIPTION: Touchscreen controller test configuration * ARG: None * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_TSCTEST * DEPENDENCIES: Board logic must provide board_tsc_teardown() */ case BOARDIOC_TSCTEST_TEARDOWN: { board_tsc_teardown(); ret = OK; } break; #endif #ifdef CONFIG_BOARDCTL_ADCTEST /* CMD: BOARDIOC_ADCTEST_SETUP * DESCRIPTION: ADC controller test configuration * ARG: None * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_ADCTEST * DEPENDENCIES: Board logic must provide board_adc_setup() */ case BOARDIOC_ADCTEST_SETUP: { ret = board_adc_setup(); } break; #endif #ifdef CONFIG_BOARDCTL_PWMTEST /* CMD: BOARDIOC_PWMTEST_SETUP * DESCRIPTION: PWM controller test configuration * ARG: None * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_PWMTEST * DEPENDENCIES: Board logic must provide board_pwm_setup() */ case BOARDIOC_PWMTEST_SETUP: { ret = board_pwm_setup(); } break; #endif #ifdef CONFIG_BOARDCTL_CANINIT /* CMD: BOARDIOC_CAN_INITIALIZE * DESCRIPTION: CAN device initialization * ARG: None * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_CANINIT * DEPENDENCIES: Board logic must provide board_can_initialize() */ case BOARDIOC_CAN_INITIALIZE: { ret = board_can_initialize(); } break; #endif #ifdef CONFIG_BOARDCTL_GRAPHICS /* CMD: BOARDIOC_GRAPHICS_SETUP * DESCRIPTION: Configure graphics that require special initialization * procedures * ARG: A pointer to an instance of struct boardioc_graphics_s * CONFIGURATION: CONFIG_LIB_BOARDCTL && CONFIG_BOARDCTL_GRAPHICS * DEPENDENCIES: Board logic must provide board_adc_setup() */ case BOARDIOC_GRAPHICS_SETUP: { FAR struct boardioc_graphics_s *setup = ( FAR struct boardioc_graphics_s *)arg; setup->dev = board_graphics_setup(setup->devno); ret = setup->dev ?
