Hi, I just begin to learn stm32 and bought the stm32l496-discovery. Initially, the LCD screen did work well and the applications were shown normally. But after I download the GPIO code into the chip through st-link, the LCD screen turned off. I don't know why this happen and how can I get back the original embedded applications?

You erased the demo app, and replaced it with code that doesn't do anything with, or initialize, the LCD?

Rebuild the demo app, or use the .HEX
