Renamed firmware.bin cannot be uploaded

I wanted to change only the name of the output firmware.bin file to something like firmware_1.2.3+567.bin, for this, I followed the example shown in the official documentation.

The 1st (not that bad) problem is:

Following the shown example does not only rename firmware.bin but it also removes the extension of the .elf file.

In addition (the 2nd problem):

When I want to upload the the code to my ESP32 MCU, it always fails because paritions.bin file cannot be found:

esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: 'C:\\Users\\ME\\Development\\MyProject\\Firmware\\.pio\\build\\debug\\partitions.bin'
*** [upload] Error 2

The problem comes for sure from renaming the file, because as soon as I remove the script from being executed from the extra_scripts uploading works properly again.

Does anyone have any solution for the uploading problem? and maybe a way to avoid the first problem?

I cant reproduce the issue.

I’m using the platformio.ini adapted for an ESP32 and the same Python code.

[env:env_custom_prog_name2]
platform = espressif32
board = esp32dev
framework = arduino
build_flags = -D VERSION=13
extra_scripts = pre:extra_script.py

and

Import("env")

my_flags = env.ParseFlags(env['BUILD_FLAGS'])
defines = {k: v for (k, v) in my_flags.get("CPPDEFINES")}
# print(defines)

env.Replace(PROGNAME="firmware_%s" % defines.get("VERSION"))

and (Verbose) uploading gives me

And all the files are there, especially the partition file.

Do you get a different result when using the exact same files per above?

After seeing that it works on your side @maxgerhardt, I kept trying until I figured out what causes the problem.

The problem is the semantic versioning format. In the platformio.ini, I have the following:

firmware_version = '"0.1.2+3"'
build_flags =
	-D FIRMWARE_VERSION=${common.firmware_version}

As soon as I add the + to the version, the problem appears, removing the plus symbol solves the problem. I am trying to find a workaround this. Please let me know if you have any suggestions.

P.S., adding - instead of + also causes the same issue.

UPDATE:

It turns out that adding any kind of characters (also english letters) in place of symbol causes the same issue. Weird.

Also hard coding the value in the python code causes the same problem. Please check these test cases:

env.Replace(PROGNAME="firmware_0.1.2+3") # <<== ISSUE TOO

env.Replace(PROGNAME="firmware_012+3") # <<== This works (notice: no periods)

env.Replace(PROGNAME="firmware_0.12+3") # <<== ISSUE TOO (one period in the string makes it does not accept characters other than digits and periods after that period, apparently).

Any ideas what is happening and how to solve this? Seems to be a bug?

@ivankravets could you also please take a look?

@maxgerhardt were you able to reproduce the issue using the format I showed in my previous analysis?

UPDATE:

After spending the whole day trying to understand and fix this, I believe this is a bug. I opened an issue on GitHub:

Please let me know if otherwise.

I could reproduce the issue with the minimal

[env:env_custom_prog_name2]
platform = espressif32
board = esp32dev
framework = arduino
extra_scripts = pre:extra_script.py
Import("env")

env.Replace(PROGNAME="firmware_0.1.2+3") # <<== ISSUE TOO

and this indeed causes the partitions.bin as well idedata.json file to be missing, although the firmware name has been applied.

So maybe it’s something specific to the Espressif32 platform. The issue should be the way to go from here.

Thank you Max for your reply.

The issue should be the way to go from here.

Sorry I did not understand what you mean? You mean the GitHub issue I opened?

Yes exactly, that should be the right starting place (even it has to be transfered maybe)
