引导时内核图像中的错误

Question

实际上，我正试图在我的Zedboard上引导linux (有zync SoC和ARM corders-A9处理器)。但没有成功。在这里，我将分享到现在的故事：-

1-我已对我的SD卡进行了第一次分区，并将其命名为Boot，并在此复制了以下内容：

BOOT.bin uEnv.txt devicetree.dtb uImage uramdisk.image.gz

现在，我试图从SD卡引导它，但它没有发生，我得到了以下信息。在这条消息中，我特别强调了错误消息，以及我在我的tty终端中得到的其他相关消息。

3.我的uenv.txt文件内容如下：

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映像：

mkimage -A ARM -T ramdisk -C gzip -n 'ZED filesystem' -d ramdisk.image.gz uramdisk.image.gz

在执行上述命令时，我收到以下消息：

因此，根据我的上述信息，请您告诉/建议我解决地雷问题。

Answer 1

您还没有将加载地址传递给mkimage。尝试向其添加-a 0x2000000参数。另外，-C gzip参数可能是错误的，因为输入文件已经被压缩。尝试使用-C none代替。
