Such that it ends at 155648+827392 = 983040 byte, if I understand it correctly. In this case I am using the generic_gcc.ld file (see above) with the flash The problem is in merging bootloder_and_settings with the app. Merging bootloader with settings work fine. So are you getting complaints about overlapping sections when you merge the bootloader and bootloader settings OR when you merge the app with the already merged bootloader + bootlaoder settings hex? If its the latter, then can you post the linker script for your application? I would like to check if you have adjusted the application flash region to allow enough space for the bootloader. What are the changes regarding DFU and bootloader from 15.0 to 15.3, would changing to 15.3 resolve these issues? * App Boot Validation Type: 0x00000000 (0)Īny idea why the mergehex complains about possible region overlapping when app and bootloader (and settings) are merged?Ĥ. Is including in the app linker file: uicr_bootloader_start_address (r) : ORIGIN = 0x00000FF8, LENGTH = 0x4 immportant?ģ. According to the memory map, MBR starts at 0, is the statement correct: mbr_params_page (r) : ORIGIN = 0x000FE000, LENGTH = 0x1000Ģ. Here is my confusion and following some questions:ġ.
One linker script for bootloader and application how to#
Clearly I have a lack of understanding, how to create the linker file, as I am trying to sort it out by looking at the examples and reading the blogs. RAM (rwx) : ORIGIN = 0x20002220, LENGTH = 0x3dde0Īll compiles well and mergehex complains that I am overlapping some regions.
Mbr_params_page (r) : ORIGIN = 0x000FE000, LENGTH = 0x1000Īnd here is the generic_gcc_nrf52.ld linker file's part for the memory:įLASH (rx) : ORIGIN = 0x26000, LENGTH = 0xca000 Uicr_mbr_params_page (r) : ORIGIN = 0x00000FFC, LENGTH = 0x4 Uicr_bootloader_start_address (r) : ORIGIN = 0x00000FF8, LENGTH = 0x4īootloader_settings_page (r) : ORIGIN = 0x000FF000, LENGTH = 0x1000 Here is the important part of the secure_bootloader.ld linker file for the bootloader:įLASH (rx) : ORIGIN = 0xf4000, LENGTH = 0xa000 Somehow there is my understanding problem with the linker for bootloader and app. We implement a DFU over USB functionality to the custom board nrf52840 board by compiling via gcc.
