HardFault inside System Init - STM32L151CBUxA

[gkowshik]

I am trying to run a code that's built using STM32L1x_Peripheral Libs for STM32L151CBUxA MCU.

As soon as I run the SystemInit function inside the ResetHandler I am hitting a Hardfault, so I investigated the SystemInit function.

Once the Vector Table relocation function is executed in it a HardFault is caused. I am unsure how to debug or resolve this.

Please help me debug the code.

Hello @gkowshik ,

Could you please provide your source code file or direct me to the example you are currently working on in order to investigate the issue on my side ?

 

With regards,

Hello @gkowshik ,

I have checked with the FSMC_SRAM_DataMemory example and can confirm that a hard fault occurs during the execution of the SystemInit function.

An internal ticket 192898 has been submitted for a detailed investigation. Please note that this tracking number is for internal use only and is not accessible to customers.

Thank you for bringing this to our attention.

 

With regards,

Hi @SHs 

Thanks for confirming this. Will await for an expert to come back on this, can you add a higher priority on this bug as this stops us from reaching the main function and cannot proceed to develop our application code.

Thanks

Wow - there's a blast from the past!!

Anyhow, on debugging Hard Faults:

@Andrew Neil Oh thanks for this man, but sadly I have already gone through your article, tried it out, root caused the instruction but I don't know WHY that instruction is causing the fault and how to resolve it. 

When I said "I did some digging into the hard fault", I did it by following your article itself hahaha. That was very nice and detailed but it didn't resolve my problem.

Thanks,
