Writing data to flash STM32L476RE

[LTim.2]

I use STM32L476RET6 and try write data to flash. I write full page (2K) it's working ecept end page (Page 383) Bank 2.

I calculate addres for page 382 bank 2: 0x0800 0000 + 0x7F000 and correct data to write.

I calculate addres for page 383 bank 2: 0x0800 0000 + 0x7F800 and data no writed. Page cleared.

I use code:

...

...

uint32_t addr = 0x807F800; // Address 383 Pages, bank 2 or 0x807F000 for 382 pages

HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, addr, data[i]);

...

...

I need help on this issue. Any help and hints are appreciated. Thank you in advance!

What value did you use for parameter data[i] while calling HAL_FLASH_Program?

In my experiment, I used just the number 0x25 (uint64_t)

Are you sure you didn't accidentally lock the page?
