Title:
qemu-system-arm: ../hw/usb/hcd-dwc2.c:666: dwc2_glbreg_read: Assertion
`addr <= GINTSTS2' failed.
Status in QEMU:
Fix Released
Bug description:
When trying to run the 2016-05-27 Raspbian image on the emulated
raspi2 platform, the system boots but shortly after the login prompt
QEMU (master; commit ID ca489cd037e4d50dc6c40570a167504ad7e5a521) dies
with:
qemu-system-arm: ../hw/usb/hcd-dwc2.c:666: dwc2_glbreg_read: Assertion
`addr <= GINTSTS2' failed.
Steps to reproduce:
1. Get the image: wget
http://downloads.raspberrypi.org/raspbian/images/raspbian-2016-05-31/2016-05-27
-raspbian-jessie.zip
2. Extract the kernel image and DTB:
sudo losetup -f --show -P 2016-05-27-raspbian-jessie.img
sudo mkdir /mnt/rpi
sudo mount /dev/loop11p1 /mnt/rpi/
cp /mnt/rpi/kernel7.img .
cp /mnt/rpi/bcm2709-rpi-2-b.dtb .
sudo umount /mnt/rpi
sudo losetup -d /dev/loop11
3. Run QEMU:
qemu-system-arm -M raspi2 -m 1G -dtb bcm2709-rpi-2-b.dtb -kernel kernel7.img
-append "rw earlyprintk loglevel=8 console=ttyAMA0,115200 dwc_otg.lpm_enable=0
root=/dev/mmcblk0p2" -sd 2016-05-27-raspbian-jessie.img -smp 4 -serial stdio
-display none
A few seconds after the login prompt is displayed, QEMU will exit with
the assertion failure.
I also tried changing all of the asserts to if statements that (for
MMIO reads) returned 0 and (for writes) just returned, but this
resulted in a non-responsive system.
