I build usually with:
../qemu/configure --cc="ccache cc" --cxx="ccache c++" --enable-debug
--enable-fdt \
--enable-kvm --enable-libusb --enable-libssh2 --enable-lzo \
--enable-bzip2 --enable-curses --enable-gtk --enable-cap-ng
Running with command:
arm-softmmu/qemu-system-arm -m 1024 -M smdkc210 -smp 2 -append \
'console=ttySAC0,115200n8 console=ttyS0 earlyprintk' -d guest_errors \
-serial stdio -D ..//log-smdkc210.log -kernel ../cur-linux/zImage
-dtb ../cur-linux/dts/exynos4210-smdkv310.dtb
-initrd ../armv7-odroidu3-exynos-v4.10-initramfs.cpio.gz
Plus the -accel line, depending on the needs.
The initramfs is a simple one from Arch Arm.

enable-debug-tcg did not change much - no asserts. The last dmesg is:
