Hi all
I found it can't backup the guest RAM when i run simple ram test code with
errors which can't backing storage for guest RAM with integratorcp, the
commander is:
qemu-system-arm -M integratorcp -m 1 -semihosting -nographic -mem-path mem.txt
-kernel build/emu_ram_test.elf
i wrote the patter "0x55" to all of the rest of RAM in my test, after run my
test code, it just generate the 1048576 Bytes file, i split these file into
2kB, most of split file is black, some of them just display \00 after open with
gedit.
i don't know whether my commander is incorrect, anyone can confirm it for me? i
just want to write the guest RAM and read it from host during the guest code is
running. but my guest just has simple os without file system and network. so i
want to try with this backend RAM ways.
thanks.
