## Build using Segger Embeded Studio ### Common makefile problems
#### 1. `arm-none-eabi-gcc`: No such file or directory
If you get the following error:
```
$ make feather52840
Compiling file: dfu_single_bank.c
/bin/sh: /usr/bin/arm-none-eabi-gcc: No such file or directory
make: *** [_build/dfu_single_bank.o] Error 127
```
You make need to edit the `Makefile` (for example `src/singlebank/Makefile`),
and update the `GNU_INSTALL_ROOT` to point to the root path of your GCC ARM
toolchain.
#### 2. `mergehex: No such file or directory`
Make sure that `mergehex` is available from the command-line. This binary is
part of of Nordic's [nRF5x Command Line Tools](http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2Fnrf5x_command_line_tools%2Fnrf5x_installation.html).

For better debugging you can also use SES, The project file is located at `src/segger/nrf52840_bootloader.emProject`. Note: the SES only flash the bootloader when you click download, you need to flash Softdevice beforehand if you haven't done so ( use `make flash_sd` mentioned above ) For better debugging you can also use SES, The project file is located at `src/segger/nrf52840_bootloader.emProject`.
