Where to find a .bin file

1

Hi, I need to find/ generate a .bin or .hex file from the current project. Where can i find/generate that file?
Im using platformIO in Visual Studio Code on a Mac.

See .pio\ folder within your project?

I see that folder, but no .hex or .bin file

Tell me what files you see in that folder.

So can you show me what’s in this hifive1 folder?

Well the .elf file is the already linked binary, you should be able to use it with flasher software like openocd etc.

If you want a hex file then you can go to your <user home folder>/.platformio/platforms/sifive/builder/main.py and replace this line by

target_buildprog = env.Alias("buildprog", target_hex, target_hex)

after recompilng there is a firmware.elf and firmware.hex file.

Alternatively you can invoke the objcopy yourself in a shell in the directory where the firmware.elf is.

<home folder>/.platformio/packages/toolchain-riscv/bin/riscv64-unknown-elf-objcopy -O ihex firmware.elf firmware.hex

(can also be used with -O binary)

However I agree that it would be usefull to build this by default. You can open an issue at the repository for it.

I need a similar solution for platform-atmelavr. Unfortunately @maxgerhardt’s solution as above does not work there, the compile process will terminate with:

NameError: name 'target_hex' is not defined:
  File "C:\Users\Micha\.platformio\penv\lib\site-packages\platformio\builder\main.py", line 168:
    env.SConscript("$BUILD_SCRIPT")
  File "C:\Users\Micha\.platformio\packages\tool-scons\script\..\engine\SCons\Script\SConscript.py", line 541:
    return _SConscript(self.fs, *files, **subst_kw)
  File "C:\Users\Micha\.platformio\packages\tool-scons\script\..\engine\SCons\Script\SConscript.py", line 250:
    exec _file_ in call_stack[-1].globals
  File "C:\Users\Micha\.platformio\platforms\atmelavr\builder\main.py", line 165:
    target_buildprog = env.Alias("buildprog", target_hex, target_hex)

So how do I manage to get the firmware.hex file being built and preserved?

Are you using up-to-date PlatformIO and platform versions? This already builds a hex file:

I stand corrected - I seem to have been chasing a phantom again… Sorry for bothering you!
