Are you using the Makefile from the SDK example to compile the bootloader project? Below is the default linker script for our Bootloader example project. In your linker script there appears to be a lot of sections missing.

Hi bjorn, I have been busy for the last 3 months.

There is not nrf52840.ld file attached to this case.

RE: DFU customize

I was upload nrf52840.ld file.

RE: DFU customize

bjorn-spockeli — Thu, 16 Jan 2020 09:12:33 GMT

If you're not able to upload the .ld file to the case, then please just copy the content of the file and paste it in a "Insert Code" block. (Click Insert -> Insert Code below)

RE: DFU customize

I tried But the overlaps error is still not clear.

RE: DFU customize

bjorn-spockeli — Wed, 15 Jan 2020 09:06:05 GMT

I do not see any .ld file attached to this case. Can you try to attach it again?

RE: DFU customize

kevin seo — Wed, 15 Jan 2020 00:03:12 GMT

My SDK version is 15.3

And the .ld file is already included. What should I modify here?

RE: DFU customize

bjorn-spockeli — Thu, 09 Jan 2020 10:24:49 GMT

Hi Kevin,

Which SDK version are you using?

The error indicates that there is an error in the linker script. Could you attach the .ld file you're using in your project?

Best regards

Bjørn
