Building of Bootloader

[Shimon_nohayo]

Hi,

I'm using SDK  nRF5_SDK_15.2.0_9412b96  and I need to build DFU and Bootloader for OTA.

I follow the "Getting started with Nordic's Secure DFU bootloader, a step by step guide" tutorial.

In the stage B1 (Compile the uECC library) I have a problem.

I've downloaded the library from GitHub and saved it in the micro-ecc\microecc folder.

I've tried to run the Makefile from \\nRF5_SDK_15.2.0_9412b96\external\micro-ecc\nrf52nf_keil\armgcc and from \\nRF5_SDK_15.2.0_9412b96\external\micro-ecc\nrf52hf_keil\armgcc

 But any time we get error.

 Please advise how can I run the MAkefile?

What error do you get?
Please attach output from make.

1. (If you don't have toolchain installed yet) download it from e.g. https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads and install it.

2. Edit settings in <NRF_SDK>\components\toolchain\gcc\Makefile.windows file

3. Open Command Prompt and go to folder where your Makefile is located

4. Run `make` (not `Makefile`!)

Hi,

I've installed "gcc-arm-none-eabi-8-2018-q4-major-win32-sha1.exe"

I've updated "\\nRF5_SDK_15.2.0_9412b96\components\toolchain\gcc\Makefile.windows"

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/8 2018-q4-major/bin/
GNU_VERSION := 8.2.1
GNU_PREFIX := arm-none-eabi

I run make from "\\nRF5_SDK_15.2.0_9412b96\external\micro-ecc\nrf52nf_keil\armgcc\Makefile"

And I get the same error: 

'make' is not recognized as an internal or external command,
operable program or batch file.

Please help

Hi, 

Please following the instruction in the Installing micro-ecc and note that 

Install version 6-2017-q2-update of the GCC compiler toolchain for ARM.

Hi Amanda,

I've installed version 6-2017-q2-update.

Can you help me understand the instruction in the Installing micro-ecc section 2 and 4 ?

Hi, 

I think you mean step. 2 and 4:

In the step. 2, you can verify make is installed by typing make -v. If it is not installed, please do it.

C:\nRF5_SDK_15.3.0_59ac345\external\micro-ecc\nrf52nf_armgcc\armgcc>make -v

In the step.4, please change directory to <SDK InstallFolder> \external\micro-ecc\ for the SoC and the toolchain that you are using to build your application.

• SDK InstallFolder\external\micro-ecc\nrf52_keil\armgcc
• SDK InstallFolder\external\micro-ecc\nrf52_iar\armgcc
• SDK InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc

For example, 

C:\nRF5_SDK_15.3.0_59ac345\external\micro-ecc\nrf52hf_keil\armgcc>make
