Hi,
I notice my dfu bootloader oversized after I merge softblink led feature into the example code. How can I modify the linker_section_placement_macros and the linker_section_placements_segments without breaking the requirement for Memory layout - Memory range nRF52840
HW: PCA10056
SW: nRF5_SDK_15.2.0_9412b96
example code: \dfu\secure_bootloader\pca10056_ble + softblink led feature
