pstorage_clear() for multiple pages with any given block size

[floatcloud]

For nrf52832, I use pstorage to set 254 blocks with 20 byte of each block, that will use near 5 pages.

now I fail to clear data all block together. pstorage_clear( &block_base_handle, 254*20) doesn't work for me.

I saw this link : devzone.nordicsemi.com/.../

but the block size need to be page aligned in that example. But block size of 20B cannot aligned with a 1024B page. Is that any other way to erase all pstorage data without changing the block size? How about bypass pstorage_clear and directly erase flash pages with address instead?

Which SDK are you using? Are you using a specific example from the SDK? Could you upload your pstorage_platform.h so I can take a look at it?

Hi, Petter. I used SDK 11. I just found out that 254*20 was larger than nrf52 page size so that it caused the issue, so I divided the data into two pstorage modules to workaround the limitation. I can clear the data now, but still would be nice if someone could have solution using a single module for this case.
