Can't get LEDs to blink on STM32F4

Testing/Troubleshooting
1

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!

Ah, silly me. The second parameter to MIOS32_BOARD_LED_Set is not on/off, its a mask of the LEDs.

Nevermind :slight_smile:
