Unknown error during running code on STM32F105R8

[Vivek pkd]

Hi all,

I have made a source code that runs fine, But after 6 months I again tried to run the same code. Now the running stuck at some point,

The code stuck at this point is shown below

Is this error occur due to any hardware failure like oscillator /capacitor

Anybody, please help???

Could be, or invalid clock settings. Put a scope on HSE to see if it's working.

The best option is measure (by osciloscope, counter, LA), that external oscilator is working. You can try PLL feed from internal HSI oscilator to check if PLL get ready.

Thanks.@TDK​  ,@ONadr.1​  , I checked with the Oscilloscope, I found some irregularities across Oscillator. So I replaced Oscillator with new one, The issue solved
