Hi,

I have not tried to import the bootloader project in SDK 11 to SES unfortunately.

Hi Vidar,

I got solution, problem is in retarget.c file of sdk 11, I replace that file with retarget.c file from your given zip folder.

Now hardware is working without debug mode. Thank you.

Now new problem has arrived, I am not able to program hardware with OTA feature.

After programming dk using dfu, it stop working. It is working with hex file of keil.

have you tried hrs_dfu example or any example with dfu?

ok, the ../../../../../../components/device path was already included in the project, and it shouldn't have been necessary to add the CMSIS if you had installed the package. Here is what I did to test it on a different other PC:

1. Downloaded a new copy of SDK 11

2. Download and extract the zip file I uploaded. Renamed the folder to ble_app_proximity and replaced it with the existing folder in SDK 11.

3. Built and programmed the app to a nRF51 DK (project located in \examples\ble_peripheral\ble_app_proximity\pca10028\s130\ses)

I am using segger version v4.12 and CMSIS pack is installed.

I had to add the CMSIS include path when I tried it on another PC. I didn't have to do it on my PC because I have installed the CMSIS package in SES. However, I was not able to reproduce the linker errors. What version of SES are you using? I have tested with v.3.40 and v4.12

Hi,

This example includes the xml file (section placement) and I have tested it on a nRF51 DK. Please include the build errors you got.

Hi vidar,

Thank you for reply.

I have try your example, have some doubts in it.

is this example is without xml file?

is this example is working fine with nrf51dk? because it is giving me error while building so I am not able to get hex file to test it on nrf51 dk.

As you mentioned above, getting started document don't have enough settings, so can you please help me with the additional settings you did in segger.

Hi,

I haven't encountered this particular problem when importing SDK 11 projects to SES, but I did find that the Getting started guide didn't include every step needed to import an example successfully. Please try the example I uploaded here and compare it against your project.
