Launch ARM raspberry 4 BSP in QEMU

[Stiff_ler]

Hello,
I’m trying to launch the QNX BSP Raspberry Pi BCM2711 R-PI4 in QEMU (qemu-system-aarch64).
My setup is QNX SDP 7.1 on Linux Ubuntu 20.04.

I downloaded the QNX SDP 7.1 BSP for Raspberry Pi BCM2711 R-PI4 package from the QNX SoftwareCenter build for cortex-a72 processor where QEMU recently added support for the raspberry 4.
I build the bsp from command line, but unfortunately I’m having a hard time figuring out how to get it to run on QEMU. Does anyone have an idea ?

Are you trying to boot the X86 version of this BSP? QNX doesn’t seem to support non-X86 in QEMU as I mentioned to you before here.

Create QNX OS virtual machine image for different architectures

Hello, I’m using QNX SDP 7.1 on Linux 20.04. I would like to create bootable disk-images for different CPU architectures(x86, armle-v7, aarch64le) on QEMU. For the purposes of QNX, QEMU is a practical tool for quick tests and troubleshooting. The SDP 7.1 provides you with the mkqnximage utility but the only QNX Guest CPU Architecture it currently supports is x86_64 so I can’t use it for creating images in armle-v7 & aarch64le. With mkifs I can create an image file system file out of a buildf…

Hi Tim,
No, it’s the arm 64 bit version I try to boot.
Yes I remember your answer to my post.
I thought with a BSP available for arm it could have been a different story, mainly because of this post so I thought maybe there is a chance someone here could have found a way around.

Interesting.

I’d check out that GitHub project and see if you can replicate what they did (get it to boot). It appears they managed it by jumping directly to the correct address in memory (go 0x40200000). I wonder how they obtained that address. It would be super helpful if there was a way to contact whomever did this to ask about that address.

You’ll also note they didn’t get networking and several other things working. Not sure if that’s because it’s ARM based or whether there isn’t QEMU emulation for the specific hardware in that board.
