MX_TIM2_Init() hangs debugging

Hi,

I use Stm32CubeMX v4. It creates the code for TIM2, TIM3 and TIM8 (STM32F103VCT, custom board). All timers have 'Clock Source == Internal Clock' and 4 channels configured to 'Input Capture direct mode'. When I debug the code with sw4stm32 v2.2.1 (ubuntu 04 x64) there is not return from 'Step over' debugging in MX_TIM2_Init(). Debugging hangs. The code is attached.

After that in addition the only way to reload (or erase) the code is to connect the reset pin of St-link v2 to MCU NRST and use 'Reset Mode == Connect under reset'.

When I comment MX_TIM2_Init() debugging is OK with 'Reset Mode == Software system reset'.

Is there a way to debug with TIM2?

Thanks for assistance,

Boris.

Hello !

The initialization code seems normal.

Is stack size appropriate? .(use callgraph to observe the maximum stack usage).

>>>there is not return from 'Step over' debugging in MX_TIM2_Init().

what about 'Step Into'? Do you have the same result?

Regards

Hello,

thank you for advices.

I can not run callgraph in sw4stm32 - 'Unhandled event loop exception

java.lang.StackOverflowError'. I increase 'Minimum stack size' in

stm32cubemx 2 times to 0x800. No effect.

I attached screens for 'Step Into'. Debugging hangs in line 112

stm32f1xx_hal_msp.c __HAL_AFIO_REMAP_TIM2_ENABLE();

Regards,

Boris.

Hello Boris

Are you use JTAG ?

__HAL_AFIO_REMAP_TIM2_ENABLE()   remaps CH1 to PA15, CH2 to PB3.  Theese pins used by JTAG also.

In this case is normal to have  ''hang'' . (JTAG can not communicate)

If you don't mind , post your .Ioc file  and also the code before the
