How to create a HEX for custom upload command?

[jcw]

I’m using a custom uploader which needs a hex file. This used to be present in the build directory, but now it seems I only get .elf and .bin build output.

Is there an easy way to force creation of hex without resorting to extra_script.py tricks?

Here’s what I have tried in platformio.ini:

upload_protocol = custom
upload_command = cat $UPLOAD_FLAGS <$BUILD_DIR/${PROGNAME}.hex
upload_flags = >$UPLOAD_PORT

Can't generate hex file using post process

Due to spaces in the paths with missing quotes the command is not interpreted correctly. You need to quote the filepaths. Write instead Import("env") # Custom HEX from ELF env.AddPostAction( "$BUILD_DIR/${PROGNAME}.elf", env.VerboseAction(" ".join([ "$OBJCOPY", "-O", "ihex", "-R", ".eeprom", '"$BUILD_DIR/${PROGNAME}.elf"', '"$BUILD_DIR/${PROGNAME}.hex"' ]), "Building $BUILD_DIR/${PROGNAME}.hex") )

Ok, thx - that will solve it. Had hoped to avoid adding a .py script, but it’s not a show-stopper.
