Hello,
Can any body suggest the sequence of initialization of on-board peripherals when multiple peripherals have to be use.
The following sequence is giving some strage exceptions.
======code on ARM9/OMAPL138 EVM, CCSV4.2.4, sysBIOS with logicPD BSL==============
GPP_POST_result.I2C_init_status = I2C_init(I2C0, I2C_CLK_400K); // init I2C channel
GPP_POST_result.timer_init_status = USTIMER_init();
System_printf("%d\t",GPP_POST_result.timer_init_status);
GPP_POST_result.LED_init_status = LED_init();
GPP_POST_result.LCD_init_status = LIDD_init();
GPP_POST_result.Flash_init_status = SPIFLASH_init();
GPP_POST_result.PB_init_status = PB_init();
GPP_POST_result.rtc_init_status = RTC_init();
GPP_POST_result.SPI_init_status = SPI_init();
GPP_POST_result.UART_DEBUG_init_status= UART_init(UART2, 9600);
GPP_POST_result.UART0_init_status= UART_init(UART0, 9600);
GPP_POST_result.UART1_init_status= UART_init(UART1, 9600);
