Manjaro ARM 22.06已经发布一段时间，刚好我们需要重新刷系统，镜像还是选用Vim2： https://github.com/manjaro-arm/vim2-images/releases
在最近的几个版本中，系统的启动方式经历了几次变化。在Vim2 22.06镜像中，boot分区只包含下述文件/目录：
$ ls -l /boot
drwxr-xr-x 8 root root 8192 Aug 3 22:49 dtbs
drwxr-xr-x 2 root root 8192 Jun 4 05:03 extlinux
-rw-r--r-- 1 root root 24730112 Jul 12 23:44 Image
-rw-r--r-- 1 root root 8382621 Aug 3 22:50 initramfs-linux.img
-rw-r--r-- 1 root root 1363968 Feb 12 00:11 u-boot.bin
需要稍加变动以支持R3300-M启动：
-rw-r--r-- 1 root root 713 Jul 28 15:17 aml_autoscript
-rw-r--r-- 1 root root 463 Jul 28 15:17 aml_autoscript.zip
drwxr-xr-x 8 root root 8192 Aug 3 22:49 dtbs
drwxr-xr-x 2 root root 8192 Jun 4 05:03 extlinux
-rw-r--r-- 1 root root 24730112 Jul 12 23:44 Image
-rw-r--r-- 1 root root 8382621 Aug 3 22:50 initramfs-linux.img
-rw-r--r-- 1 root root 537 Aug 4 06:34 s905_autoscript
-rw-r--r-- 1 root root 1363968 Feb 12 00:11 u-boot.bin
-rw-r--r-- 1 root root 609247 Aug 4 06:30 u-boot.ext
注意补充的几个文件，u-boot.bin可以删掉。这几个文件我已经打包好： bootfiles.tgz，注意你需要选择合适的u-boot文件，然后重命名为u-boot.ext。
Manjaro ARM Mininal 22.06非常简洁，总共占用空间1.5GB，提供了206个软件包：
$ df -h
Filesystem Size Used Avail Use% Mounted on
dev 331M 0 331M 0% /dev
run 465M 7.5M 457M 2% /run
/dev/mmcblk0p2 115G 1.4G 109G 2% /
tmpfs 465M 0 465M 0% /dev/shm
tmpfs 465M 0 465M 0% /tmp
/dev/mmcblk0p1 458M 45M 413M 10% /boot
tmpfs 93M 0 93M 0% /run/user/1000
$ pacman -Q | wc
206 412 3746
软件包还可以继续精简，比如 ap6398s-firmware 显然可以删掉因为R3300-M使用的是RTL8189ETV。另外经过测试，主线内核在22.06中支持良好，关机重启都正常，没必要使用odroid内核了。不过Vim2镜像自带的 linux-khadas 内核简单使用也没发现问题，根据个人喜好选用吧。
另外之前将Manjaro ARM安装到emmc分区的试验没有成功：

Resetting CPU ...
虽说没成功，但是从UART输出来看已经很接近，而且盒子也没变砖，还是可以从TF卡启动，感兴趣的可以继续研究，我不缺TF卡就不折腾了。
