USB port too

No one is delayed.

my new USB disk

I did not use g_mass_storage because I found that the kernel would crash when unloading this module. I used the Android gadget and I recommend this gadget because it can be used with one more gadgets at the same time. You are right. I will upload the full sources during my spare time. The following are the core codes : if [ -b "/dev/mmcblk0p2" ]; then echo "$_disk" > /sys/class/android_usb/f_mass_storage/lun1/file echo "$_disk2" > /sys/class/android_usb/f_mass_storage/lun2/file else echo "0" > /sys/class/android_usb/f_mass_storage/lun2/ro echo "0" > /sys/class/android_usb/f_mass_storage/lun2/removable echo "/dev/mmcblk0" > /sys/class/android_usb/f_mass_storage/lun2/file fi echo "USBoot" > /sys/class/android_usb/android0/iManufacturer echo "USBootPi" > /sys/class/android_usb/android0/iProduct echo "f833" > /sys/class/android_usb/android0/idVendor echo "0001" > /sys/class/android_usb/android0/idProduct echo "mass_storage" > /sys/class/android_usb/android0/functions echo "2" > /sys/bus/platform/devices/sunxi_usb_udc/otg_role echo "1" > /sys/class/android_usb/android0/enable

v1.3 is released, RAID0 is supported. I tested the maximum speeds of the OTG. The maximum speeds are the same as the above CrystalDiskMark's result. I did some tries for improving the speeds but they did not work. I think the speeds should be improved because the CPU utilization is still low when the maximum speeds reach. Who can tell me the actual reason about it?

8G Class4

The english readme is ready: https://github.com/usboot/USBootPi

I made a funny project for trying to use the ARM single board as the USB disk or cdrom. I did a lot of optimizations for the size and speed. Releases: https://github.com/usboot/USBootPi/releases USBootPi supports NanoPi M1. It also supports OrangePi One/PC but we need more USB cables(one for power, another one for OTG). Sorry, there is no the English readme now.
