Re: [U-Boot] qemu-system-arm segfaults on zynq_zed

I don't think boot.bin is a legal "kernel". IIRC, I had issues running on QEMU, but it was slightly better than what you describe.

The result is:

then a register dump

The "boot.bin" and "devicetree.dtb" is from xilinx binary release 2014.3-release/zed

I tried removing -smp 2 -machine linux=on, and same error. On Mon, Nov 24, 2014 at 9:21 AM, Sören Brinkmann <[1]soren.brinkmann@xilinx.com> wrote:

 Could you try whether these instructions work?
