Do sd_flash_write or sd_flash_page_erase verify the result of the flash operation?

[Marius Heil]

Hi,

do sd_flash_page_erase or sd_flash_write provide any guarantees that the command has executed successfully or should I do a manual check to verify if the page was really erased or the data was written correctly?

Thanks, Marius

Hi,

There is no automatic verification of flash content (sd_flash_page_erase /sd_flash_write will not read back the data), so this is something you can add if you want (though I have not heard of this being a problem, and we don't do that ourselves).

Mr. Sigurd, if you can answer this one last (I promise) question, that would be great!
