ARM, RISC-V контроллеры

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 */ void HardFault_HandlerC(unsigned long *hardfault_args){ volatile unsigned long stacked_r0 ; volatile unsigned long stacked_r1 ; volatile unsigned long stacked_r2 ; volatile unsigned long stacked_r3 ; volatile unsigned long stacked_r12 ; volatile unsigned long stacked_lr ; volatile unsigned long stacked_pc ; volatile unsigned long stacked_psr ; volatile unsigned long _CFSR ; volatile unsigned long _HFSR ; volatile unsigned long _DFSR ; volatile unsigned long _AFSR ; volatile unsigned long _BFAR ; volatile unsigned long _MMAR ; stacked_r0 = ((unsigned long)hardfault_args[0]) ; stacked_r1 = ((unsigned long)hardfault_args[1]) ; stacked_r2 = ((unsigned long)hardfault_args[2]) ; stacked_r3 = ((unsigned long)hardfault_args[3]) ; stacked_r12 = ((unsigned long)hardfault_args[4]) ; stacked_lr = ((unsigned long)hardfault_args[5]) ; stacked_pc = ((unsigned long)hardfault_args[6]) ; stacked_psr = ((unsigned long)hardfault_args[7]) ; // Configurable Fault Status Register // Consists of MMSR, BFSR and UFSR _CFSR = (*((volatile unsigned long *)(0xE000ED28))) ; // Hard Fault Status Register _HFSR = (*((volatile unsigned long *)(0xE000ED2C))) ; // Debug Fault Status Register _DFSR = (*((volatile unsigned long *)(0xE000ED30))) ; // Auxiliary Fault Status Register _AFSR = (*((volatile unsigned long *)(0xE000ED3C))) ; // Read the Fault Address Registers.
