Arduino IDE 2.3.6 & esptool warnings

[OK1FWG]

Hi,
thanks for your effort creating this useful tool. Great job!
My system throw out these warnings:

Warning: Deprecated: Option '--flash_mode' is deprecated. Use '--flash-mode' instead.
Warning: Deprecated: Option '--flash_freq' is deprecated. Use '--flash-freq' instead.
Warning: Deprecated: Option '--flash_size' is deprecated. Use '--flash-size' instead.
Warning: Deprecated: Choice 'default_reset' for option '--before' is deprecated. Use 'default-reset' instead.
Warning: Deprecated: Choice 'hard_reset' for option '--after' is deprecated. Use 'hard-reset' instead.
Warning: Deprecated: Command 'write_flash' is deprecated. Use 'write-flash' instead.
esptool v5.0.0

May be, you noticed this already, just FYI.
Thanks & regards,
Willi

Yes, I noticed that with the latest core releases. They like to change things just to change them. 😭

I'm going to leave this as it is until they completely remove the original options. This way users of older cores can still use this, in addition to users of the latest ones.

Yeah same here. I got these warnings:
Warning: Deprecated: Option '--flash_mode' is deprecated. Use '--flash-mode' instead. Warning: Deprecated: Option '--flash_freq' is deprecated. Use '--flash-freq' instead. Warning: Deprecated: Option '--flash_size' is deprecated. Use '--flash-size' instead. Warning: Deprecated: Choice 'default_reset' for option '--before' is deprecated. Use 'default-reset' instead. Warning: Deprecated: Choice 'hard_reset' for option '--after' is deprecated. Use 'hard-reset' instead. Warning: Deprecated: Command 'write_flash' is deprecated. Use 'write-flash' instead. esptool v5.1.0

But yeah I agree with you @earlephilhower
I will wait.

Hi I am using Arduino 2.3.6 at this moment.

Gemini created a python script for me

#!/usr/bin/env python3
import sys
import os
import subprocess

script_dir = os.path.dirname(os.path.realpath(__file__))
esptool_binary = os.path.join(script_dir, "esptool")
args = sys.argv[1:]
command = [esptool_binary] + args

subprocess.run(command)

place it in
/home/popcorn/.arduino15/packages/esp32/tools/esptool_py/5.1.0

chmod +x esptool.py

and I think it will work now?

That's AI slop and unrelated to this issue.

It's a 1 line change of some underscores to dashes in the Typescript to change the calling parameters. No need for some random Python script which looks like it just calls the binary (which we already do) with the exact same args passed to it.
