GrovePi+ does not work after firmware and software updates

Hi,

I have two GrovePi+ Starter Kit for Raspberry Pi. They are not version 3. I beliew the kits have GrovePi+ version 2 (because they look different than the current model picture on the website). These GrovePi+ hats used to work with my RaspberryPi model 3B+. And I could run any of the supplied Python scripts. For example, to blink the LED.

However now, after updating the software and firmware, following the below SeeedStudio instructions, the Python scripts do NOT work.


1>> Has anyone else had this problem?
2>> Does the above firmware only work with GrovePi+ version 3?
3>> What is the solution to this problem? Does the firmware need to be reset?

Thanks for any advice or feedback!

Best Regards,
Gussan H.
