BLE_SensorDEMO built in TrueSTUDIO is not working on idb007v1

Posted on February 16, 2018 at 20:28

Hi,

I'm trying to run an example program - BLE_Sensor DEMO - built from sources.

I am using TrueSTUDIO for STM32 (v.9.0.0). The sources are from BlueNRG-1.2_DK_2.6.0 kit.

Unfortunatelly, when I download the image, the board does nothing: no led blinking, no BLE communication.

However, when I download prebuilt image (from Firmware folder in the development kit) it works fine.

What I am doing wrong?

Kind regards,

Piotr

TrueSTUDIO project from ST DevKit has missing architecture option:

   -mcpu=cortex-m0

Without that linked libc contains instructions in ARM mode (but it should be only Thumb - because it is Cortex-M0).

That is why HardFault Exception occured. 

How to fix it

The option should be added in:

   Project Properties | C/C++ Build |Settings, tab Tool Settings

for each group:

  Assembler, C Compiler, C Linker

in Miscellaneouos |Other options field.

It's almost certainly doing something - so connect the debugger, and find out what it's doing!

Hi Andrew,

I did, but debugging from TrueStudio, does not work either!

Please read my question:

https://community.st.com/0D50X00009Xkht2SAB

I expected that reference design from ST should work, but not to be debugged.

My configuration constains:

- the board from ST,

- TrueSTUDIO (ST recommended as one of the IDE)

- development kit from ST (library and TrueStudio project)

- jtag/programmer from ST

Regards,

Piotr

OP? What does it mean?

Would have been helpful to include that in the OP, then.

Closer look to program execution show that it does not return to main() from BlueNRG_Stack_Initialization().

Inside the function HardFault exception is generated.

Here is a stack trace:

Unfortunatelly not. I still cannot debug from TrueSTUDIO IDE.

Above data is from BlueNRG-ST-Link Utility. This tool has very limitted functionality, but enough for getting ARM core register and RAM contents. 

I have taken function names from a listing generated by the linker.

Sounds like something to do with Floating Point - so check your FP setup.

Trying to do hardware FP on a chip with no FP HW probably would give a Hard Fault ...

Does this mean you've got the debugger to work, then?
