No hex and bin files output

[Lozeonjyu]

Hi,

I was trying to use my L073+SX1261 shield to load the code but I couldn't find the bin file. When I trace back the makefile under "apps" I can see

create_bin_output(${PROJECT_NAME}-${CLASS}) create_hex_output(${PROJECT_NAME}-${CLASS})

Should these two commands generate the hex and bin files? If not, how can I generate the bin file or load the code to L073?

Thanks

Hi Lozeonjyu,

Should these two commands generate the hex and bin files?

Yes. After a succssful build, you will find the binaries in directory (e.g. LoRaMac Class A) build/src/apps/LoRaMac.

That's wired. I didn't see it. Could that be the setup problem? I was told that I should see a map file after generate but I couldn't find that either. I am sure I am looking at the right directory.

Hi Lozeonjyu, which commands did you run. Generally, you have to run CMake and after that run Make to generate/build the bin and hex files. Could you also provide which tools you are using to build the executables?

Actually, I used CMake-GUI. specified toolchain-arm-none-eabi.cmake as toolchain, configured, then generated.

Before that I make sure I have tools installed (windows): Cmake GNU Arm Embedded Toolchain MinGW OpenOCD

Please, could you also provide a screenshot of your CMake-GUI settings and your paths. This will be useful to figure out if it's a configuration issue. Are you able to run generate without any errors?

Hi,

plase take a look at the Wiki: Development-environment. The easiest way to verify if your build system is setup correctly is to run cmake on the console. After you have cloned the repository, you could do:

$: cd LoRaMac-node $: mkdir build $: cd build $: cmake -DCMAKE_TOOLCHAIN_FILE="cmake/toolchain-arm-none-eabi.cmake" -DTOOLCHAIN_PREFIX="/path/to/the/toolchain" -G "MinGW Makefiles" ..

[mluis1]

In plus of the commands provided by @djaeckle you need to run the make command. $: make

Please find below an example provided on issue #504

Please, could you also provide a screenshot of your CMake-GUI settings and your paths. This will be useful to figure out if it's a configuration issue. Are you able to run generate without any errors?

Please check the pics below:

Config:

Generate:

It seems all right according to the message window. No warning/error pop-ups during config and generate.

Environment variable on my laptop:

Thanks a lot. 😃

Thanks guys @djaeckle @mluis1 I will try on the console. I used GUI at the first place because it is easier for me to do the config.

[mluis1]

You must execute the make command after using your GUI. The cmake-gui only generates the makefiles. The make command is the one that performs the compilation tasks based on the cmake-gui generated makefiles.

Got it! Problem solved. On windows with MinGW the make command is ming32-make.exe Thanks for reminding, it saves me a lot of time.
