Hi,

I am working on HDMI - HDMI firmware is loading is proper with single bootloader, but dual bootloader firmware loading is not proper,

 

Single bootloader:

u-boot-imx8qm.imx


=> md 0x84002000

Is there any problem with dual bootloader ?

Is there any problem with trusty OS ?

Hi @igorpadykov ,

 

Finally, the issues are resolved long time back. For Android Automotive build, the hdmitx firmware was removed from final image.
