I'm sorry, but I'm not familiar with "iapfun jump2app". It seems to be a specific term or tool that I am not aware of. Could you please provide more information or context about it?

void JumpAPP(void) { uint32_t JumpAddress; pFunction Jump_To_Application; //Check if ((*(__IO uint32_t*) FLASH_APP_ADDR) == 0x20020000) // RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K { //printf("APP Start...\n"); HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, GPIO_PIN_RESET); HAL_Delay(1); // Jump to user application // JumpAddress = *(__IO uint32_t*) (FLASH_APP_ADDR + 4); Jump_To_Application = (pFunction) JumpAddress; // Initialize user application's Stack Pointer // __set_MSP(*(__IO uint32_t*) FLASH_APP_ADDR); //reset stack top; optional if stack to not changed HAL_Delay(10); Jump_To_Application(); //jump to app reset responding procedure } else { //No APP found! } }讲解一下这个函数
这个函数是一个用于跳转到用户应用程序的函数。它首先检查用户应用程序的地址是否为x20020000,如果是,则将GPIOA的第个引脚设置为低电平,延时1毫秒后跳转到用户应用程序。如果用户应用程序地址不是x20020000,则表示没有找到用户应用程序。在跳转到用户应用程序之前,还可以选择重置堆栈指针。
