Recently I have been trying to use the UARTS on the board using the peripherals library and also Keil uVision 4 for debugging and I keep getting the following error message: ***error 65: access violation at 0x40023800 no 'write' permission for the following line of code in the system_stm32f4xx.c file:
/* Reset the RCC clock configuration to the default reset state ------------*/ /* Set HSION bit */ RCC->CR |= (uint32_t)0x00000001; /* Reset CFGR register */ RCC->CFGR = 0x00000000; /* Reset HSEON, CSSON and PLLON bits */ RCC->CR &= (uint32_t)0xFEF6FFFF; /* Reset PLLCFGR register */ RCC->PLLCFGR = 0x24003010; /* Reset HSEBYP bit */ RCC->CR &= (uint32_t)0xFFFBFFFF; /* Disable all interrupts */ RCC->CIR = 0x00000000;
