Hi!
I am using STMCube IDE and a STM32G030F6
I am trying to implement a code that writes variables to the flash. And I was able to make it work, with some limitations...
THIS CODE WORKS
union
{
uint8_t regs[6];
uint64_t data;
} mem;
uint64_t *my_pointer;
my_pointer = (uint64_t *)0x08007000; // base address of page 14
if(*my_pointer == 0xFFFFFFFFFFFFFFFF) // if the memory is blank
{
HAL_FLASH_Unlock();
mem.regs[0] = 25;
mem.regs[1] = 50;
mem.regs[2] = 75;
mem.regs[3] = 100;
mem.regs[4] = 1;
mem.regs[5] = 0;
HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 0x08007000, mem.data);
HAL_FLASH_Lock();
}
I run this code in the initialization of the board, the first time the program runs it will enter the if...
Instead of using
HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD...
I'd like to use:
HAL_FLASH_Program(FLASH_TYPEPROGRAM_FAST...
But i am not able to make it work... it crashes all the time in the function:
static void FLASH_Program_Fast(uint32_t Address, uint32_t DataAddress);
What is the best way to write a series of variables in the flash? I plan to write more than 20 uint16_t...
