![]() QEMU doesn’t seem to like either of the two UBoot kernels. TFTP from server 10.0.2.2 our IP address is 10.0.2.15ĭHCP client bound to address 10.0.2.15 (0 ms) *** Warning - bad CRC, using default environment Qemu-system-arm: qemu_mprotect_osdep: mprotect failed: Permission denied I had to kill it.Ĭuriously, I tried another build of the UBoot kernel, this time from the FreeBSD project: u-boot-qemu-arm-2021.07.txz FreeBSD 13 Download, and got farther with it! QEMU again gave me a screenful of those same errors as above, but proceeded: qemu-system-arm: qemu_mprotect_osdep: mprotect failed: Permission denied QEMU was using 100% of one core, but seemingly not doing anything. When I ran it on my MBA M1, the output was a screenful of qemu-system-arm: qemu_mprotect_osdep: mprotect failed: Permission denied, then nothing. Lastly, here’s the qemu command I used: qemu-system-arm -machine virt,highmem=off \ Incidentally, it will also build the mkimage executable in the tools directory it can be used. The building process will create a u-boot.bin image that supports ramdisks for the VersatilePB. ![]() I followed the instructions on NixOS on ARM/QEMU page and downloaded uboot.bin from Hydra - Job nixpkgs:trunk:ubootQemuAarch64.aarch64-linux (specifically from this build). To apply the patch: n n n - save the patch to a file, for example /u-boot-2010.03.patch n - download u-boot-2010.03 source tree and extract it. I believe this needs to be a UBoot build prepared for QEMU. Then I ran into the challenge of finding a suitable QEMU kernel. I downloaded a AArch64 installer image from Hydra ( ). I’ve done a lot of research but haven’t found the root cause. So, I am trying to boot an ARM image of NixOS in QEMU on my MacBook Air M1, but I have not been able to so far. Having the ability to run it on my laptop would make it more convenient to prepare the rootfs, as well as to quickly and easily recover from a bad SD card. My goal is to run NixOS on Raspberry Pi 4B, but with the ability to run the environment on my laptop in addition to the RPi hardware. The mkimage utility can be built with U-Boot by following instructions from the Building Bootloader web page on RocketBoards.
