Hi
I was using SDK 2.4.1 and was able to download the program to STM32F4 Discovery board using JTAG , (I used a simple LED blink program).
Now I have moved to SDK 3.1.0 and facing some issue while programming via JTAG ,finally followed seyhan's comment to add line reset_config trst_and_srst in /tools/OpenOCD/jlink.cfg , and I was able to download the program to STM32F4 .
But the code doesn't seems to be running. THe LED's are not lighting
What might be causing the issue?
Regards
HpC

Finally got it working....
Since the LSE crystal was not present in the STM32F4 Discovery I had to use the LSI (Internal oscillator)
Changes
had to edit the function platform_mcu_powersave_init(),
/* Enable the LSE OSC */
RCC_LSEConfig(RCC_LSE_ON);
/* Wait till LSE is ready */
while(RCC_GetFlagStatus(RCC_FLAG_LSERDY) == RESET)
{
}
to
RCC_LSICmd(ENABLE);
/* Wait till LSE is ready */
while(RCC_GetFlagStatus(RCC_FLAG_LSIRDY) == RESET)
{
}

Hi,
Are you using Segger Jlink JTAG debugger?
After downloading the program, did you try to reset the target board?

1. Yes I'm using Jlink Base from Segger.
2. I even tried power on resetting the target board , still no effect.
Is there anything else to add in jlink.cfg file ?
Please help ...

I have used the Olimex to interface and test it.
I have not tested with Segger Jlink. I will give it a try.

Great thanks.... ,
I'm expecting the reply as fast as possible , as we are running out of schedule..
By the way which version of SDK are you using for STM32F4 DIscovery code flashing ?
I think the issue is more related on the configuration/platform initialization....
Update on Debugging: When I tried debugging , I could see that the program never reaches application_start(); , it gets looped in the the while(RCC_GetFlagStatus(RCC_FLAG_LSERDY) == RESET);
and the RCC_GetFlagStatus always return RESET ,This function is called in platform_result_t platform_mcu_powersave_init( void );
So On checking I found that LSE oscillator (32 Khz) is not fitted on the STM32F4 Discovery board.
So how did you managed to make the code work in the Discovery board ? Or Am I missing something?
Note : For Interfacing STM32Fx-Discovery with WICED using JTAG Debugger (used jlink Segger ) I had to connect VTref pin to the Vdd of STM32F4 to make it working(for flashing the code),

Hi,
Another option is to disable power save by defining WICED_DISABLE_MCU_POWERSAVE in the make file or in .../include/wiced_defaults.h

Thanks,
Just want to know why are we using platform_mcu_powersave_init() , what is the real advantage of using that function?

Hi,
The platform_mcu_powersave_init() initializes the RTC which is used for MCU power save.
Please refer to .../doc/WICED-AN104-R-Powersave-App-Note.pdf for more information.

Hi I tried enabling
WICED_DISABLE_MCU_POWERSAVE in the make file or in .../include/wiced_defaults.h
but couldn't find another place where it is defined..
I'm getting these erros..
