Hello,
I am currently experimenting with some throughput tests on nRF52832/nRF52840 DKs. Some time ago I worked with some BLE UART examples from SDK 13.0 with the help of Eclipse. Everything worked fine after going through this tutorial. Now I wanted to extend the btt_app_att_mtu_throughput example from SDK 14.1.0 and started by "converting" it to an Eclipse project like before.
- changed Compiler command pattern under Project Properties -> C/C++ General -> Preprocessor Include Paths -> Providers -> CDT Build Output Parser to (.gcc)|(.[gc]++) and removed tick on Use heuristics to resolve paths
- replaced ${COMMAND} under CDT ARM Cross GCC Bult-in Compiler Settings with arm-none-eabi-gcc
- replaced Makefile.common under …/SDK14.1.0/components/toolchain/gcc with the patched one from the tutorial, but removed "/bin/" from toolchain commands ("CC:= '$(GNU_INSTALL_ROOT)$(GNU_PREFIX)-gcc'"), as an error was thrown and changed the calling of "[…]file_list.mk" to "[…]dump.mk"
- initiated make clean, make all and rebuilt the index
My build output looks something like this (shortened!):
'/opt/gcc-arm-none-eabi-6-2017-q1-update/bin/arm-none-eabi-gcc' -MP -MD -std=c99 -O3 -g3 -D[…] -mcpu=cortex-m4 -mthumb -mabi=aapcs -Wall -Werror -mfloat-abi=hard -mfpu=fpv4-sp-d16 -ffunction-sections -fdata-sections -fno-strict-aliasing -fno-builtin -fshort-enums -I"<SDK_ROOT/x>" -I"<SDK_ROOT/y>"-I"<SDK_ROOT/z>"[…]
So, I guess it looks fine. Seems to be the same, like in my other projects, but there are no entries for the include files listed under Project Properties -> C/C++ General -> Preprocessor Include Paths -> Entries -> GNU C, except for the Compiler Settings under the same tab. The output parser is working fine in my other older projects.
Additionally, with the modified makefile.common I am running into a warning at the end of the build process:
/opt/gcc-arm-none-eabi-6-2017-q1-update/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/bin/ld: warning: cannot find entry symbol Reset_Handler; defaulting to 0000000000023000
I am not very "skilled" in writing Makefiles, so maybe there are some issues with the new file I am missing. So, is there anything I haven't thought of?
Thank you very much!
Regards, Björn
