Building Mesh Bootloader via makefile

[Justin]

I'm attempting to pull the mesh bootloader out of the sdk and put it in its own makefile project, so it can be built separately.

I'm building with `gcc-arm-none-eabi-7-2017-q4-major` for an nRF52832.

The bootloader builds successfully, however when I flash and run I get an error in the application code (a modified mesh lightswitch).

<t:         87>, mesh_softdevice_init.c,  117, Initializing SoftDevice...

<t:          0>, mesh_softdevice_init.c,   75, Enabling BLE...

<t:        549>, app_error_weak.c,   87, Application memory access: 493818:0

If i use the pre-built bootloader hex, it works successfully.

Any suggestions on what I might be missing?

Here is the build output for my project:

Hi Jay, 

Could you send your make file of the bootloader project ? 

We had an issue with our spam filter. It's fixed now , now you can edit your question. 

[Justin]

i attempted to attach the makefile to the original post, but it didn't seem to work, so here it is:

PROJECT_NAME := mesh-bootloader

export OUTPUT_FILENAME
MAKEFILE_NAME := $(MAKEFILE_LIST)
MAKEFILE_DIR := $(dir $(MAKEFILE_NAME) )

TEMPLATE_PATH = ./sdk/nRF5_SDK/components/toolchain/gcc

include $(TEMPLATE_PATH)/Makefile.common

ifeq ($(OS),Windows_NT)
include $(TEMPLATE_PATH)/Makefile.windows
else
include $(TEMPLATE_PATH)/Makefile.posix
endif

SDK_ROOT := $(abspath ./sdk/nRF5_SDK)
PROJ_DIR := $(abspath ./)
MESH_ROOT := $(abspath ./sdk/MESH_SDK)

#echo suspend
ifeq ("$(VERBOSE)","1")
NO_ECHO :=
else
NO_ECHO := @
endif

#function for removing duplicates in a list
remduplicates = $(strip $(if $1,$(firstword $1) $(call remduplicates,$(filter-out $(firstword $1),$1))))

Hi Jay, 

Thanks for the file. We would be interested to know what you have in your .ld file. 

There is one thing special about the bootloader is that it requires a dedicated "core ram" section. 

If you have a look at the .ld files here: 

https://github.com/NordicPlayground/nRF51-ble-bcast-mesh/tree/develop/DFU/nRF51/bootloader/gcc

You can find in gcc_bl_nrf52832_xxAA.ld the CORE_BL_RAM section is defined and then used in gcc_bl_nrf52_common.ld . 

This bootloader was for our old mesh stack (broadcast mesh) but it's almost identical to the bootloader in our newer mesh SDK.

i am using an unmodified linker file from the mesh SDK:

Thanks Jay, we will try to test here and get back to you.

Hi again Jay, sorry for the late response, was off on Friday. 

In our .ld we expecting the object file to be .c.obj, but in your make file you use: C_OBJECTS = $(addprefix $(OBJECT_DIRECTORY)/, $(C_SOURCE_FILE_NAMES:.c=.o) ) seems that it will be .o 

Could you try changing the file lists in the .ld file to .o instead of ".c.obj" and see if that works ? 

[Justin]

good catch, that seems to have been the issue.
thanks!
