Date: Mon, 10 Jul 2017 09:14:58 +0000 [thread overview]
Message-ID: <B1DA44315104F94D9F3F23C74275EA9D729B34@Ikerlan-12.ikerlan.es> (raw)
Hello!
I need to modify the source code of QEMU to apply a little change. My final idea is to prove the utility of a virtual platform as a way of reusing software designed for an obsolete hardware. For that I've created a "real timer", connected to my board. Now... the problem:
My standalone program writes "0xffffffff" in the position 0x95000000 when the timer should start, and "0x00000000" when it have to finish. I want to modify the code so every single (standalone) program step reads the virtual 0x95000000 and changes the value of a gpio. But I can't find how I can read from the source code the virtual memory, and I can't find neither where/how does the program process (step by step) the standalone program.
I don't know if I have explained well my doubts...
Thankyou in advance!
Xabi
