After reading your email I thought I'd try just a couple of more additions (because gradually removing will take so long..) and tried adding the most suspicious ones. Then I found CONFIG_SERIAL_AMBA_PL011, CONFIG_SERIAL_AMBA_PL011_CONSOLE and CONFIG_SERIAL_EARLYCON_ARM_SEMIHOST were not set! (qemu virt machine uses PL011 not PL010 which was set). After this addition, it boots ok to the shell! I was very luck.. 😊 Thank you, Best regards, Chan Kim _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
