Resolved! Factory default value of FLASH_OPTR

Hello,I would like to know the behavior of the BOOT0 pin on a factory fresh STM32G474 device. I'm wondering if I can use PB6 as a general input without causing side effects if the flash option register is at factory defaults. The reference manual sh...

I use HAL_FLASH_Program to program my internal flash, but it takes too much time, I program about 90kbytes, it will take about 90 seconds. Is there any faster way to program stm32l072.

my pagesize is 256 bytes, and 90k is about 351 pages  for(i = 0; i < pages; i++)  {    W25qxx_ReadPage((uint8_t *)u32_databuf, EXT_FLASH_ADDR_APP_START + i,0, w25qxx.PageSize);    ProgramInternalFlash(APP_BASE_ADDR + i * w25qxx.PageSize, u32_databuf,...
