nRF52832 FLASH write issue

[zzzZ]

I want to write a piece of big data to flash.
Every time I write 112 word length, I write it many times.
Every time I write, the address is shifted back 112.
Before I write, I need to erase the pages that need to be written.
However, I find that only the first time I write successfully, but later I write unsuccessfully.
The API I use is sd_flash_write, what's the reason? thank you!

May your show your processing code? I can't understand your meaning in your statement.

It's re-write 112 words (uint32_t)in original address , or write next 112 words in next 112 offset address.
