Notes: 1, 5 * LED7 Yellow ~SD0 Controlled via PJ7. Notes: 1, 6 * ----- ------ ------ ------------------------------------ * * Note 1: Pulled high so a low output illuminates the LED. * Note 2: PH2/~RF is also used by the RF transceiver, X2. That part is not * populated on my board. * Note 3: ~SXM is the chip select for the serial memory, U4. That part is * not populated on my board. * Note 4: ~SD1 is the chip select for the SD card 1, X11. * Note 5: ~SD2 is the chip select for the SD card 2, X10. * Note 6: ~SD0 is the chip select for the microSD 0, X12. * * In conclusion: None of the LEDs are available to indicate software status * without potentially sacrificing board functionality. If the RF transceiver * is not installed (CONFIG_16Z_RFTRANSCEIVER=n) and if LED support is * requested (CONFIG_ARCH_LEDS), then LED3 will be used to indicate status: A * solid color means that the board has boot successfully; flashing at a rate * of approximately 2Hz indicates a software failure. */ #define __LED3_BIT (1 << 0) #define __LED4_BIT (1 << 1) #undef HAVE_16Z_LED3 #undef HAVE_16Z_LED4 #if !defined(CONFIG_16Z_RFTRANSCEIVER) # define __LEDPANIC __LED3_BIT # define HAVE_16Z_LED3 #elif !defined(CONFIG_16Z_SERIAL_MEMORY) # define __LEDPANIC __LED4_BIT # define HAVE_16Z_LED4 #else # define __LEDPANIC (0) #endif #if !defined(CONFIG_16Z_SERIAL_MEMORY) && !defined(HAVE_16Z_LED4) # define __LEDSTARTED __LED4_BIT # define HAVE_16Z_LED4 #else # define __LEDSTARTED __LEDPANIC #endif /* LED3 LED4 */ #define LED_STARTED 0 /* OFF OFF */ #define LED_HEAPALLOCATE 0 /* N/C N/C */ #define LED_IRQSENABLED 0 /* N/C N/C */ #define LED_STACKCREATED __LEDSTARTED /* N/C ON */ #define LED_INIRQ 0 /* N/C N/C */ #define LED_SIGNAL 0 /* N/C N/C */ #define LED_ASSERTION 0 /* N/C N/C */ #define LED_PANIC __LEDPANIC /* ON N/C */ /**************************************************************************** * Public Functions ****************************************************************************/ #undef EXTERN #if defined(__cplusplus) #define EXTERN extern "C" extern "C" { #else #define EXTERN extern #endif #undef EXTERN #if defined(__cplusplus) } #endif #endif /* __CONFIGS_16Z_INCLUDE_BOARD_H */
