Hi, As my custom machine is based on cortex-m3 I checked the stellaris.c https://github.com/qemu/qemu/blob/stable-4.2/hw/arm/stellaris.c#1384,1390. Does only this part define the UART peripheral for this machine? Can you point out any basic examples so that I can refer to ARM M3. Any help would b

Dear qemu developers I built an image for e5500 cpu with yocto and run with qemu ppce500 machine: qemu-system-ppc64 -nographic -M ppce500 -cpu e5500 -kernel uImage -initrd core-image-minimal.rootfs.ext2.gz -append 'root=/dev/ram rw' It works well, but as the emulated guest is in idle state, in the

Now there are some many UART implemented in the hw/char. What should we look for or how do you choose which one to use? or implement similar kind. Same case for I2C also. I'm new to these so can you suggest me the basic one so that I can try and implement it? Thank you, Abhijeet. On Wed, Sep 1
