Включил новую плату на Кинетисе. Hardfault. pc=0x30. Вектор прерывания #define VECTOR_012 default_isr // 0x0000_0030 12 - ARM core Debug Monitor. Что за хрень? Аналогичный проект на том же контроллере работает. /**
* HardFaultHandler_C:
* This is called from the HardFault_HandlerAsm with a pointer the Fault stack
* as the parameter. We can then read the values from the stack and place them
* into local variables for ease of reading.
* We then read the various Fault Status and Address Registers to help decode
* cause of the fault.
* The function ends with a BKPT instruction to force control back into the debugger
