Overlapping hex files

Hi, I’m trying to program my nrf52840 dongle. I did have followed the steps from the nrf52840 programming tutorial, but I have some issues.

I’m trying to write the USB CDC ACM example with the softdevice but the hex files are overlapping. I did research on the devzone for people with the same problem but it didn’t helped me out.

Can someone explain me how I can fix this or did I do something wrong.

Hi I did fixed this problem. But for now I have another problem for the engineer.
I want to use the usbd_ble_uart example. I get an error in the ble_nus.c.

blcm_link_ctx_get(…. p_link_ctx_storage,….)

No member named p_link_ctx_storage.

Hello,

That's strange, the project should compile without errors. Any chance the ble_nus.h/ble_nus.c sources may been modified? I would suggest that you try again with a new SDK copy just to be sure.

Best regards,

Hi, the SES version you use is not compatible with the retarget.c file included the ble_app_uart projects. Please see my post here for more details: https://devzone.nordicsemi.com/f/nordic-q-a/88123/build-environment-problem/368739#368739

Hi, I did disabled retarget and removed RTT_Syscalls from my project, but that's not enough? Should I downgrade it?

Meanwhile I did the downgrade, but after building I got this error. Am I missing something?

You also need to set the IO output to 'RTT' in your project as explained in Einar's post.

Your project is including the wrong version of the thumb_crt0.s file for some reason. What is the path to file (you can hover the mouse over the thumb_crt0.s tab to see it)?

Yes, this was the step I forget. But when I’m doing this I don’t see anything printed on the uart com-port. Is that true.

It takes it from the ses 6.22. I didn’t erase the full application in case it wouldn’t work with the downgraded version.
