我正在尝试使用dwc2
和g_mass_storage
(使用最后一个可用的 Raspbian 图像)将 Raspberry Pi Zero 设置为大容量存储。我用 . 创建了数据存储文件dd
,用mkdosfs
. 我找了很多东西。花了一些时间才明白,options应该是传入的/etc/modprobe.d/g_mass_storage.conf
,终于在ubuntu中看到了。我的问题是:它处于只读模式。
我试图将ro
选项设置为对行为y
或n
不产生任何影响。我更改了文件(777)的权限,它没有改变。这是我/etc/modprobe.d/g_mass_storage.conf
文件的当前内容:
options g_mass_storage file=/piusb.bin stall=0 removable=y ro=n
这是dmesg

如何获得读/写大容量存储?
