Recently I plan to customize QEMU for my own embedded system. The content of 
customization is to add a new QEMU monitor command, so that I can use this 
command to directly modify the value of specific main memory space. I know it's 
dangerous to directly write in memory. But I really need this function. Could 
you give me some tutorial about memory management of QEMU and how to add new 
QEMU monitor command so that I could know how to customize QEMU, eg, which lib 
I should call in QEMU?
Can't you do what you need to do already through the gdbstub?


And BTW, my specific board is ref405ep.

I don't think so. Because the content should be written in memory is large and it should be written fast and I hope I can use this function even though in other platform, eg, ARM architecture emulated in QEMU. So I think if possible, I would prefer to write specific value through QEMU monitor command.
