Re: qemu: fatal: lockup...

How important are these lines https://github.com/qemu/qemu/blob/stable-4.2/target/arm/cpu.c#L1928-#L1929.

 Anyways I will use the newer Qemu but curious was this a problem in my building? 

Please let me know so that I can move forward. It's really important for me.

I will look into the latest one. Can you elaborate on that please! 

And I'm running a test.elf for the similar machine which I'm building. It runs test only if the given size of the flash and RAM are double of the required/being used size. How? Is there any offset kind of thing that needs to be changed or I wandering I'm doing something wrong?

Those lines aren't board-specific, they are an
architectural requirement on the CPU. They set up the
default memory permissions (executable or not) when the
MPU is disabled.

Also, you're looking at QEMU 4.2 there, which is now
pretty old. If you're actively developing a new board
model, use the most recent QEMU at least, and preferably
head-of-git.
