Hi,I am using Franco Kernel with patch,the roms in the USB shows in the boot menu, but when I chose one to boot,the internal rom starts instead of the rom I selected in the USB.Roms in the internal storage works well.

What device do you have and what filesystem do you have on the flash drive?

frameartist commented 10 years ago

Filesystem : fat32 Device :Nexus 4 Kernel : franco kernel from here

This time I successfully booted android L developer preview from USB,but neither Cyanogenmod nor Firefox OS could boot from USB

I am unable to reproduce this on my flo. After it crashes (that's why it boots into internal) and boots, can you get me the dmesg? Something like this:

adb shell
su
dmesg > /sdcard/dmesg.txt

There should be file "dmesg.txt" on your /sdcard now, you can get it with adb pull or some other method. Put it on pastebin.com or somewhere please.

I tried two times and got 2 logs http://pastebin.com/8f3jYGnM http://pastebin.com/VRgmVkbG thanks

Oh, so you select the ROM, it reboots (you see the google logo again) and starts internal? According to the logs, it is unable to find the USB drive after the reboot, I assume it has something to do with the way USB-OTG is borked on mako. Make sure the kernel in the secondary ROM you want to boot supports USB-OTG by default.
