1. I am using STM32 with keil v5. 2. In my code I am getting hardfault, however I don't see any error in "fault report" option of keil. 3. What could be error?
4. Attached is pic. www.docdroid.net/.../pic.pdf.html
You have a call to a default interrupt handler. This is not necessarily the hard fault but could be any interrupt in your system that is enabled.\
I suggest you review the interrupts that are enabled in the NVIC and verify that you have implemented for every interrupt an IRQ service function.
Thanks, that was the error.
