Problem Description
Output window displays the following two syntax warnings during verify/compile:
/home/{user}/.arduino15/packages/esp8266/hardware/esp8266/3.1.2/tools/elf2bin.py:54: SyntaxWarning: invalid escape sequence '\s'
words = re.split('\s+', line)
/home/{user}/.arduino15/packages/esp8266/hardware/esp8266/3.1.2/tools/elf2bin.py:73: SyntaxWarning: invalid escape sequence '\s'
words = re.split('\s+', line)
I guess that the escape sequence '\s' should be replace by a space character, but since I do not know how elf2bin.py file works, I did not submit a commit.
words = re.split(' +', line)
