Error when building ble_app_beacon

[DMS]

Hello,

I have been trying to test the ble_app_beacon example code that comes with SDK11.0 and upon building I got the following error:

linking...
.\_build\nrf52832_xxaa_s132.axf: error: L6002U: Could not open file .\_build\rtt_syscalls_keil.o: No such file or directory
Finished: 0 information, 0 warning, 0 error and 1 fatal error messages.

Upon trying the ble_app_beacon code of SDK12.2.0 I didn't get this error, but the board doesn't do anything upon uploading the hex file.

I am using the nRF52832 development board and building using keil uvision5.

I use arm5_no_packs, pca10040 and s123 versions of the code with my specific board. 

I have observed that uploading experimental_ble_app_blinky using SDK11.0 causes the board perform required operation (advertising LED lights up), but using the SDK12.2.0 uploads successfully but doesn't perform any function.  

I tested the pre-compiled hex files of ble_app_beacon and experimental_ble_app_blinky from the "hex" folder and these worked fine after uploading to the board.

I suspect that the above is because, the .axf files that gets uploaded(590KB for beacon and 634 for blinky) by keil for SDK12.2.0 exceed the 512KB memory limit of my board whereas they are ~400KB in case of SDK11.0 which is within the memory limit.

Please find the files I have mentioned above here : https://drive.google.com/open?id=1V97CDpJKI3gt0_JHcKdFnuTtlk4YJ7KM 

Please suggest any solutions for the error that i got for SDK11.0 or ways for me to decrease the size of the .axf files generated by SDK12.2.0,

Thank you.

The below thread helped me resolve the SDK12.2.0 issue

I just had to flash softdevice from keil itself, instead of using nRFgo studio for that.

Many thanks @Jørgen Holmefjord

However I'd still be interested in the error that was caused in SDK11.0

Hello,

Try adding the --reduce_paths option in target options to see if that helps.

Max. path length in windows is 255 characters.

Unfortunately, the error persists in SD11.0 even with this change.

In case the project files or dependencies have been modified: please try the same with a clean copy of SDK 11.0 if you haven't already.  You may also try to place the SDK folder closer to the root directory in order to shorten the path length.

You were right, the SDK copy I was using had been modified earlier by someone else. Using a fresh copy of the SDK solved my problems. Thank you.
