Question

我一直在在线研究通过“ bitbake qt5-image”命令创建的文件为树莓派创建可启动SD卡（通过USB适配器）的正确方法。构建过程成功完成，没有警告或错误。我认为与目标有关的结果文件是：

在〜/ rpi / build / tmp / deploy / images / raspberrypi中：

`“ modules-raspberrypi.tgz”链接至

modules-1-4.14.73 + git0 + e117f3e9fd-r0-raspberrypi-20181009142103.tgz 17.mb

"qt5-image-raspberrypi.tar.xz" link to

qt5-image-raspberrypi-20181009142103.rootfs.tar.xz                    92.8 mb

"zImage" link to

zImage-1-4.14.73+git0+e117f3e9fd-r0-raspberrypi-20181009142103.bin    4.7mb

我还从本教程（https://jumpnowtek.com/rpi/Raspberry-Pi-Systems-with-Yocto.html）中获取了一些有关构建之前步骤的建议。

对此事的任何建议将不胜感激！

编辑（我从zimage的build / conf / local.conf中将KERNEL_IMAGETYPE更改为=“ Image”）

Answer 1

如果您将最新的meta-raspberrypi层用作计算机层，那么您将在tmp/deploy/images/raspberrypi中获得WIC图像作为输出。

此图像可以直接闪入SD卡，因为它已经分区为

# short-description: Create Raspberry Pi SD card image
# long-description: Creates a partitioned SD card image for use with
# Raspberry Pi. Boot files are located in the first vfat partition.

part /boot --source bootimg-partition --ondisk mmcblk0 --fstype=vfat --label boot --active --align 4096 --size 20
part / --source rootfs --ondisk mmcblk0 --fstype=ext4 --label root --align 4096

因此，您无需手动对SD卡进行分区并复制相应的文件。
