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

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 ?

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

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.

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.
