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
