keves Posted November 25, 2014 Report Share Posted November 25, 2014 Hello, I got my STM32F4 board today, and for reasons beyond my understanding I cannot get any LEDs other than LED1 to light up. I am modifying the application template - so my code is as minimalistic as it gets. If I call MIOS32_BOARD_LED_Set(1,1), the green LED turns on. MIOS32_BOARD_LED_Set(2,1) or even MIOS32_BOARD_LED_Set(0xF, 1) do nothing. Some answers to potentially obvious questions: 1) I am certain I am properly recompiling the code and uploading, as I see the green led no longer lighting up when trying MIOS32_BOARD_LED_Set(2, 1) and lighting up again when I switch to MIOS32_BOARD_LED_Set(0xF, 1). 2) I tried commenting out the code in the timer function and simply turning the LEDs on in APP_Init() 3) I am compiling using the following env variables: export PATH=$PATH:/Users/eran/Projects/mutebox/gcc-arm-none-eabi-4_7-2013q3/bin export MIOS32_PATH=/Users/eran/Projects/mutebox/mios32-svn export MIOS32_BIN_PATH=$MIOS_PATH/bin export MIOS32_GCC_PREFIX=arm-none-eabi export MIOS32_FAMILY=STM32F4xx export MIOS32_PROCESSOR=STM32F407VG export MIOS32_BOARD=MBHP_CORE_STM32F4 export MIOS32_LCD=universal What am I missing? Thanks! Quote Link to comment Share on other sites More sharing options...
keves Posted November 27, 2014 Author Report Share Posted November 27, 2014 Ah, silly me. The second parameter to MIOS32_BOARD_LED_Set is not on/off, its a mask of the LEDs. Nevermind :) 1 Quote Link to comment Share on other sites More sharing options...
