感觉还有别的因素在影响？CI 也是 7.0.0，应该都是正常的

注意到你这个 make run 使用了不同的参数，试了一下，也没问题

还有一个不同点是我没有你的脚本里提到的 riscv64.img，用的是我自己构造的

elliott10 commented 2 years ago

再次试验了另外一台Ubuntu 20.04.4的机器，发现还是与Qemu有关。 某个版本的qemu-7可以运行，另外一个版本的qemu-7（应该是更加新的版本）却出了错。 对于出现的这个问题，也可作为检验dtb设备树解析库兼容性的一种方式。兼容尽量多的dtb设备树是必要的，以再更多不同版本的系统上运行好zCore。 甚至我认为能兼容到2020年发布的qemu-4/5就最好了，在于新的ubuntu-20长期发行版，默认apt安装的Qemu版本会在v4，这会是许多人的默认运行环境。
