As you are using embedded linux system on target board and Chromium 71.0 instead of "ChromeDriver 2.45" ->"chromedriver_linux64.zip" you need to download chromedriver-v2.21-linux-armv7l from this link and use it within your program as follows:

from selenium.webdriver.chrome.options import Options
from selenium import webdriver
opts=Options()
opts.binary_location='/path/to/chrome' #Chromium 71.0 executable binary
driver = webdriver.Chrome(chrome_options=opts, executable_path='/path/to/chromedriver.exe')

  • I did as you said but it still doesn't work. It prompts "Message: 'chromedriver' executable needs to be in PATH", seems the chromedriver not match with my platform. – underdog Jan 28 '19 at 02:42
  • I got such reply from chromium.org: Comment 4 by johnchen@chromium.org, Today (9 hours ago) Project Member Labels: -Needs-Feedback Status: WontFix (was: Unconfirmed) We don't support chromedriver on arm CPU, and have never release a build of chromedriver that runs on arm. Since chromedriver is open source, anyone can download its source code and compile for any architecture, but we don't have the resource to support such usages. You might try to contact the site where you obtained your copy of chromedriver. – underdog Jan 30 '19 at 01:48
