CONFIG_IMG_ERASE_PROGRESSIVELY
¶
Erase flash progressively when receiving new firmware
Type: bool
Help¶
If enabled, flash is erased as necessary when receiving new firmware, instead of erasing the whole image slot at once. This is necessary on some hardware that has long erase times, to prevent long wait times at the beginning of the DFU process.
Direct dependencies¶
MCUBOOT_IMG_MANAGER
&& IMG_MANAGER
(Includes any dependencies from ifs and menus.)
Defaults¶
No defaults. Implicitly defaults to n
.
