Okay, following your latest instructions to use Wind32DiskImager to install the older image of Raspbian for Robots, “2017.04.02_Dexter_Industries_jessie.img” instead of “2017.06.21_Dexter_Industries_jessie.img”, I have some success. Connecting directly to an HDMI TV monitor, I can see the Pi’s desktop. I still could not use my HDMI-to-VGA adaptor with this image of Raspbian for Robots.
Also, I was able to connect with PuTTY and access my Pi3 files via Samba. This is how my blind and visually impaired students have been accessing the Pi. This connectivity approach greatly reduces the need to have a monitor connected to the Pi.
I tried to update the older image, “2017.04.02_Dexter_Industries_jessie.img” by clicking on the Update icon on the Pi3’s desktop. But after the lengthy update process, I was back to the original issue of the Pi3 not completing its bootup process and losing its connection to the HDMI monitor. I had to go back and reinstall the older image, “2017.04.02_Dexter_Industries_jessie.img”.
As it stands, I should be good with this older image, right? Thanks for helping me get this up and running.
Also, I’m having issues connecting the Pi3 with my Windows 10 computer using VNC Viewer. I’m sure this is me not doing the setup procedure correctly. Can you give me the correct steps or direct me to the webpage?
Thanks again, and if you have ideas about why the latest image of “Raspbian for Robots” is not working for my Pi3 and want me to do some test, let me know.
