实际上我正试图在我的Zedboard上启动linux（使用带有ARM cortex-A9处理器的zync SoC）。但没有成功。在这里，我将分享这个故事： -
1-我已经完成了我的SD卡的第一个分区，并将其命名为Boot，我在这里复制了以下内容： -
BOOT.bin
uEnv.txt
devicetree.dtb
的uImage
uramdisk.image.gz
2-现在我正在尝试从SD卡启动它，但它没有发生，我收到以下消息。在此消息中，我特别突出显示了错误消息以及我在tty终端中获得的其他相关消息。

3-我的uenv.txt文件的内容如下： -
boot_Zed=mmcinfo;fatload mmc 0 0x3000000 ${kernel_image}; fatload mmc 0 0x2A00000 ${devicetree_image}; fatload mmc 0 0x2000000 ${ramdisk_image}; bootm 0x3000000 0x2000000 0x2A00000
uenvcmd=run boot_Zed
4-我通过以下命令创建了ramdiskimage： -
mkimage -A ARM -T ramdisk -C gzip -n 'ZED filesystem' -d ramdisk.image.gz uramdisk.image.gz
执行上述命令后，我收到以下消息： -

基于我的上述信息，请您告诉/建议我解决我的问题。
答案 0 :(得分：0)
您尚未将加载地址传递给mkimage。尝试向其添加-a 0x2000000参数。
另外-C gzip参数可能是错误的，因为您获取已经压缩的输入文件。请尝试使用-C none。
