Which means host internet network can't be accessed by emulated machine. I would be glad to help in documentation of differences between real Raspberry Pi devices and QEMU emulated raspi2/raspi3 since I have seen a lot of tutorials on internet trying to use QEMU for emulating raspberry pi. These tutorials most of the times are just hacks, like using versatilepb or using custom kernel instead of the Raspbian OS. I have gathered as much info as possible over the last week through these tutorials, QEMU raspi code and change logs, and believe a good documentation of this info could help future users trying to emulate raspi. Finally, I am able to run latest Raspbian OS (2019-07-10) lite version on raspi2 using the following command where I have extracted kernel image and dtb file from second partition: qemu-system-arm -M raspi2 -kernel bootpart/kernel7l.img -dtb bootpart/bcm2709-rpi-2-b.dtb -drive file=3D2019-07-10-raspbian-buster- lite.img,format=3Draw,if=3Dsd -append "rw console=3DttyAMA0 loglevel=3D8 root=3D/dev/mmcblk0p2 fsck.repair=3Dyes rootwait memtest=3D1" -serial stdio I am not able to connect network devices, not able to use images other than lite image (https://bugs.launchpad.net/qemu/+bug/1837347) and unsure why this command is showing Hardware name as BCM2835 when the QEMU raspi code has BCM2836 associated with raspi2 (https://github.com/qemu/qemu/blob/59c58f96b270f5edd4ad10954c3a96556cb3a728= /hw/arm/bcm2836.c#L31). I highly appreciate the support provided for raspi2 and raspi3 till now.
