Thank you for your reply, I will try a different card. I am using a Patriot 32GB card now.
I’ve came across this thread : Inky Frame not refreshing screen on battery power using inky_frame.sleep_for() - #31 by jon3 and loaded kapetzel firmware. Works like a charm now.
I don’t get mount errors. I also have a smaller (5.7") size running an older version of your slideshow and works very well,never hangs up and it’s a pleasure to have it. If I get a new card and fixes the issue I’ll update here.
Thanks again.
