Is it that I need to add emulation for CP10 and CP11? On Mon, Aug 20, 2018 at 8:29 PM Martin Schroeder wrote: > > Sent it off as reply instead of reply all.. my bad. > > I was also surprised that it was mid into an instruction. The code > works fine on STM32 but if FPU is not enabled on the STM32

Sent it off as reply instead of reply all.. my bad. I was also surprised that it was mid into an instruction. The code works fine on STM32 but if FPU is not enabled on the STM32 then I believe the code will fault in much the same way. I have had this problem before and it was also hard faulting in

[Qemu-devel] Simulating a composite machine

2018-08-19 Thread Martin Schroeder via Qemu-devel
Is it possible to instantiate multiple CPUs of different architectures and simuate them with different images at the same time? Some examples include ARM socs with m3/m4 coprocessor core but also boards with multiple processors where it is desirable to connect the chips over for example virtual SPI
