CONFIG_BOOTLOADER_SRAM_SIZE¶
SRAM reserved for bootloader
Type: int
Help¶
This option specifies the amount of SRAM (measure in kB) reserved for a bootloader image, when either: - the Zephyr image itself is to act as the bootloader, or - Zephyr is a !XIP image, which implicitly assumes existence of a bootloader that loads the Zephyr !XIP image onto SRAM.
Direct dependencies¶
(SOC_CC3220SF && SOC_SERIES_CC32XX) || (SOC_CC3235SF && SOC_SERIES_CC32XX) || ((!XIP || IS_BOOTLOADER) && (ARM || XTENSA))
(Includes any dependencies from ifs and menus.)
