So. I try now with a "basic" kernel for dingux. I add rootfs in virtual hard drive ( qcow2 ), who is formated in fat32 with one partition ( like a standard SD card ). But nothing.
For launching qemu, i use this command line :
@debianDesktop:~/$ qemu-system-mipsel -M a320 -kernel zImage -hda dingoo.qcow2
Warning: vlan 0 with no nics
VNC server running on `::1:5900'
jz4740_cpu_reset: UNIMPLEMENTED!
For launch VNC ( mmmmh, before that, I never use VNC, I prefer ssh or other command lines ) :
@debianDesktop:~$ xvnc4viewer :5900
