I am trying to update my 7"(standard model) nextion display it use to update fine, had the same program running for a year. Decided to load a new version
The SD card is formated to FAT32
what I am getting on the screen is
SD Card Update......
And thats all it does not update just stays like that
Using the same card as before when it was working fine
