Migrating From Dunfell to Kirkstone LCD over SPI using FBTFT no longer working
Hello ST Dear ST Community,
I'm currently trying to migrate my solution from stm32mp1-openstlinux-5-4-dunfell-mp1-20-06-24 to stm32mp1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15
Im using a ST7789V Based LCD, and its working trough /dev/fb0 and fbdev under /video/
fbtft and /video/fbdev under dunfell sources
however in the kirkstone distro stuff are different , i only see staging/fbtft , i managed to get the right configuration and activate it the LCD driver is loaded
in the boot it shows this

Also when probing the SPI outputs , the device seems to generate control signals when using the command fb-test
I appreciate any help, I'm open to other methods as long as it gets the LCD working again
Thank you
