I m displaying logo and text "REVOS" for 1 second before main screen and during same time display is flickering. When I was storing data in internal flash, there was no such issue.

Thanks

Hello,

What board are you using ?

Maybe your QSPI Flash is not initialized correctly. Is it only the text flickering or other assets such as bitmaps as well ?

Only text was flickering but it got solved with change in clock speed for QSPI.

Previously i was using QSPI prescaler as 2 (means 200/3 = 66.7 mhz) but when i changed to 1 ( means clock speed 200/2 = 100 mhz) issue got solved.

Perfect. Good to know you solved your issue 👍
