1. xx.s 在启动文件找到HardFault_Handler。并修改。
HardFault_Handler\PROCEXPORT HardFault_Handler [WEAK]MOV R0, spIMPORT HardFault_Handler_CBL HardFault_Handler_CENDP2. 定义HardFault_Handler_C函数。主要是打印信息并存储Flash
void HardFault_Handler_C(unsigned int* hardfault_args) {HardFault_t info;info.r0 ((unsigned long)hardfault_args[0]);info.r1 ((unsigned long)hardfault_args[1]);info.r2 ((unsigned long)hardfault_args[2]);info.r3 ((unsigned long)hardfault_args[3]);info.r12 ((unsigned long)hardfault_args[4]);info.lr ((unsigned long)hardfault_args[5]);info.pc ((unsigned long)hardfault_args[6]);info.psr ((unsigned long)hardfault_args[7]);info.BFAR (*((volatile unsigned long*)(0xE000ED38)));info.CFSR (*((volatile unsigned long*)(0xE000ED28)));info.HFSR (*((volatile unsigned long*)(0xE000ED2C)));info.DFSR (*((volatile unsigned long*)(0xE000ED30)));info.AFSR (*((volatile unsigned long*)(0xE000ED3C)));info.SCB_SHCSR SCB-SHCSR;uint8_t data[70], len 0;len snprintf((char *)data,70, \n[Hard fault handler - all num in hex] %x\r\n, *hardfault_args);McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, R0 %x\r\nR1 %x\r\nR2 %x\r\nR3 %x\r\n, info.r0, info.r1, info.r2, info.r3);McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, R12 %x\r\n, info.r12);McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, LR [R14] %x,subroutine call return address\r\n, info.lr);McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, PC [R15] %x,program counter\r\n, info.pc);McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, PSR %x\r\nBFAR %lx\r\n, info.psr, (*((volatile unsigned long*)(0xE000ED38))));McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, CFSR %lx\r\nHFSR %lx\r\nDFSR %lx\r\n,(*((volatile unsigned long*)(0xE000ED28))), (*((volatile unsigned long*)(0xE000ED2C))), (*((volatile unsigned long*)(0xE000ED30))));McuUartWriteString(ble_uart, data, len);len snprintf((char *)data,70, AFSR %lx\r\nSCB_SHCSR %x\r\n,(*((volatile unsigned long*)(0xE000ED3C))), SCB-SHCSR);McuUartWriteString(ble_uart, data, len);info.event 0;kv_set_env(0xFF00, info, sizeof(HardFault_t)); // 记录到Flashwhile (1);
}3. 根据回读PC和LR地址通过MAP文件找到对应位置判断引起硬件错误的原因。
二、定义DefaultISR查看是否有中断未声明
#define VECTORNUM (*(volatile uint32_t*)(0xE000ED04))
void DefaultISR(void) {HardFault_t info;uint8_t data[50], len;len sprintf((char *)data, \n default_isr %d,%x \n, (uint8_t)VECTORNUM, (uint32_t)VECTORNUM);McuUartWriteString(ble_uart, data, len);info.event 1;info.VECTORNUM_ADDR VECTORNUM;kv_set_env(0xFF00, info, sizeof(HardFault_t)); // 记录到Flashwhile(1);
}根据打印出来的数据判断VECTOR是怎么原因触发中断的。查对应芯片向量表得知导致原因。 三、如果使用了RTX则需要重定义osRtxErrorNotify函数。
uint32_t osRtxErrorNotify(uint32_t code, void* object_id) {HardFault_t info;(void)object_id;uint8_t data[100], len 0;switch (code) {case osRtxErrorStackOverflow:len sprintf((char *)data, \n Stack overflow detected for thread (thread_id0x%x)\n, (uint32_t)object_id);McuUartWriteString(ble_uart, data, len);// Stack overflow detected for thread (thread_idobject_id)break;case osRtxErrorISRQueueOverflow:len sprintf((char *)data, \n ISR Queue overflow detected when inserting object 0x%x\n, (uint32_t)object_id);McuUartWriteString(ble_uart, data, len);// ISR Queue overflow detected when inserting object (object_id)break;case osRtxErrorTimerQueueOverflow:len sprintf((char *)data, \n User Timer Callback Queue overflow detected for timer (timer_id0x%x)\n, (uint32_t)object_id);McuUartWriteString(ble_uart, data, len);// User Timer Callback Queue overflow detected for timer (timer_idobject_id)break;case osRtxErrorClibSpace:len sprintf((char *)data, \n Standard C/C library libspace not available: increase OS_THREAD_LIBSPACE_NUM 0x%x\n, (uint32_t)object_id);McuUartWriteString(ble_uart, data, len);// Standard C/C library libspace not available: increase OS_THREAD_LIBSPACE_NUMbreak;case osRtxErrorClibMutex:len sprintf((char *)data, \n Standard C/C library mutex initialization failed 0x%x\n, (uint32_t)object_id);McuUartWriteString(ble_uart, data, len);// Standard C/C library mutex initialization failedbreak;default:// Reservedbreak;}info.event 2;info.RTX_CODE code;info.RTX_OBJ_ID (uint32_t)object_id;kv_set_env(0xFF00, info, sizeof(HardFault_t)); // 记录到Flashfor (;;) {}// return 0U;
}四、读取错误信息
采用ATCMD读取如下
#ifdef ATCMD_EN
// 在功能模块中定义一个标准函数
static int atcmd_backtrack(atcmd_pack_t *pack) {HardFault_t *info NULL;uint8_t buff[100], len;info kv_get_env(0xFF00);if (info NULL) {strcat((char*)buff, AT_ERROR);} else {if (info-event 0) {len snprintf((char *)buff, 100, R0 %x\r\nR1 %x\r\nR2 %x\r\nR3 %x\r\nR12 %x\r\n, info-r0, info-r1, info-r2, info-r3, info-r12);pack-reply(buff, strlen((char*)buff));len snprintf((char *)buff, 100, LR [R14] %x,subroutine call return address\r\n, info-lr);pack-reply(buff, strlen((char*)buff));len snprintf((char *)buff, 100, PC [R15] %x,program counter\r\n, info-pc);pack-reply(buff, strlen((char*)buff));len snprintf((char *)buff, 100, PSR %x\r\nBFAR %lx\r\n, info-psr, (*((volatile unsigned long*)(0xE000ED38))));pack-reply(buff, strlen((char*)buff));len snprintf((char *)buff, 100, CFSR %lx\r\nHFSR %lx\r\nDFSR %lx\r\n,(*((volatile unsigned long*)(0xE000ED28))), (*((volatile unsigned long*)(0xE000ED2C))), (*((volatile unsigned long*)(0xE000ED30))));pack-reply(buff, strlen((char*)buff));len snprintf((char *)buff, 100, AFSR %lx\r\nSCB_SHCSR %x\r\n,(*((volatile unsigned long*)(0xE000ED3C))), SCB-SHCSR);pack-reply(buff, strlen((char*)buff));memset(buff, 0, 100);} else if (info-event 1) {len snprintf((char *)buff, 100, \n default_isr %d,%x \n, (uint8_t)info-VECTORNUM_ADDR, (uint32_t)info-VECTORNUM_ADDR);} else if (info-event 2) {len snprintf((char *)buff, 100, \n RTX_ERR CODE0x%x, OBJ_ID0x%x \n, (uint8_t)info-RTX_CODE, (uint32_t)info-RTX_OBJ_ID);}strcat((char*)buff, AT_OK);}pack-reply(buff, strlen((char*)buff));return 0;
