Usb Download Gadget Fastboot UPD

Neither fastboot nor ADB can recognize the phone, I think this is because the USB debugging must have turned off somehow even though I turned it on, as before I WAS able to access it through fastboot. But now I can not, plugging it into the Windows machine, windows doesn't see any change in Device Manager when the phone is plugged in and out.

There are a log of Fastboot blogs out there but what they don't always mention is, Samsung devices have no fastboot mode. So if yours is a Samsung device, don't waste time on any of the drivers and settings, because it will not work on Samsung. You can use adb but not fastboot.

Hello, This may be due to the host PC selects an incorrect driver model of the USB devices, leading to the PC inability to find fastboot device. After accessing fastboot, run "reboot bootloader" in console after boot, in host side open...

We had been suspecting the same.

However we now tried with Driver Signature enforcement disabled( bcdedit command returns nointegritychecks as Yes), but the device still shows as a USB Download gadget(This is in a Windows 11 PC).

I have compiled an image for UF896 from the repository of @kirdes, but I feel like a stupid one because I have no idea how I can flash the thing to the device. (I have no experience with fastboot or edl.)

(Note: I already erased and formatted the system, userdata and cache partitions and flashed the boot partition, and the device does not boot anymore into the vendor's operating system, just to fastboot.)

The USB gadget commands for Android Fastboot, DFU and the mass storage gadgettake a partition description which describes which barebox partitions are exported via USB.The partition description is referred to as in the command help texts. It hasthe general form partition(name)flags,partition(name)flags,....

barebox can provide a serial console over USB. This can be initialized with theusbserial - serial gadget enable/disable command. Once the host is plugged in it should show anew serial device, on Linux for example /dev/ttyACM0.

barebox has support for the android fastboot protocol. There is no dedicated commandfor initializing the fastboot protocol, instead it is integrated into the MultifunctionComposite Gadget, see usbgadget - Create USB Gadget multifunction device for a usage description.

fastboot flash additionally supports image types UBI and Barebox. For UBIImages and a MTD device as target, ubiformat is called. For a Barebox imagewith an available barebox update handler for the fastboot exported device, thebarebox_update is called.

With the Composite Multifunction Gadget it is possible to create a USB device withmultiple functions. A useful combination is creating a Fastboot gadget and a USB serialconsole. This combination can be created with:

Barebox can be configured to start usbgadget automatically by using global variables,instead of creating boot script. This can be useful if autostart policy should bechosen at boot time from other driver or script.To get usbgadget autostart support barebox has to be compiled withCONFIG_USB_GADGET_AUTOSTART enabled.

In "Flashing images using fastboot", I ran the "fastboot" command on u-boot.

Next, I ran the "sudo ./fastboot oem format" command on the host PC (ubuntu on VirtualBox).

However, nothing seems to be done.

5.2 In case of Host OS is Windows: run VirtualBox as administrator;

6. Run Virtual OS and after login enable USB device using top toolbar:

Devices -> USB -> Renesas USB download gadget

7. Please, check USB devices on VM:

Hi both,

sorry for delay.

actually i tried these few days back by changing snapcraft.yaml and gadget,yaml involving only emmc stuff as ondra said since i dont want sdcard to come in to picture.everything went fine except the size of writable only 236M. Then i followed your instructions and it booted fine.

Command used to build an image -

sudo dragonboard-builder.build-uc-image -c stable -O imagefile --extra-snaps kernel/olimex-kernel_0.1_armhf.snap --extra-snaps gadget/olimex-gadget_0.1_armhf.snap

model/olimex-lime2.model

Yes we need two separate images, first image(u-boot-sunxi-with-spl.bin) which is used to make the device in fastboot boot mode.

Once we are in fastboot mode we flash rest of the image into the emmc i.e u-boot binary and writable image.

dragonboard builder will give you file per partition, as long as gadget has those files

so if you need 1st stage bootloader and u-boot as separate files and gadget has those, as separate files. Then you should be good, just make sure gadget.yaml represent correctly your part table

Notice the difference? You'll just need to add a period and a slash (./) before the word "fastboot." If your computer required this of you for the "fastboot devices" command, you'll need to do it for all other Fastboot commands (e.g., ./fastboot flashing unlock or ./fastboot reboot-bootloader).

In order to achieve this goal, we have combined the imx-usb-loader tool with the fastboot support in U-Boot and some scripting. Thanks to this combination of a tool, running a single script is sufficient to perform the factory flashing, or even restore an already flashed device back to a known state.

Fastboot is a protocol originally created for Android, which is used primarily to modify the flash filesystem via a USB connection from a host computer. Most Android systems run a bootloader that implements the fastboot protocol, and therefore can be reflashed from a host computer running the corresponding fastboot tool. It sounded like a good candidate for the second step of our factory flashing process, to actually flash the different parts of our system.

The fastboot documentation in U-Boot can be found in the source code, in the doc/README.android-fastboot file. A description of the available fastboot options in U-Boot can be found in this documentation as well as examples. This gives us the device side of the protocol.

Fastboot needs a user-space program on the host computer side to talk to the board. This tool can be found in the Android SDK and is often available through packages in many Linux distributions. However, to make things easier and like we did for imx-usb-loader, we sent a patch to add the Android tools such as fastboot and adb to the Buildroot build system. As of this writing, our patch is still waiting to be applied by the Buildroot maintainers.

For its flashing feature, fastboot identifies the different parts of the system by names. U-Boot maps those names to the name of GPT partitions, so your eMMC normally requires to be partitioned using a GPT partition table and not an old MBR partition table. For example, provided your eMMC has a GPT partition called rootfs, you can do:

To work around this problem, we patched U-Boot to allow the fastboot flash command to use an absolute offset in the eMMC instead of a partition name. Instead of displaying an error if a partition does not exists, fastboot tries to use the name as an absolute offset. This allowed us to use MBR partitions and to flash at defined offset our images, including U-Boot. For example, to flash U-Boot, we use:

The patch adding this work around in U-Boot can be found at 0001-fastboot-allow-to-flash-at-a-given-address.patch. We are working on implementing a better solution that can potentially be accepted upstream.

Of course, this configuration is only used for the U-Boot sent using imx-usb-loader. The final U-Boot flashed on the device will not have the same configuration. To distinguish the two images, we named the U-Boot image dedicated to fastboot uboot_DO_NOT_TOUCH.

However, there is no CONFIG type for NOR storage. Sending a fastboot flash command from the host machine result in the following response from the U-Boot console.

Not support flash command for current device 0

send: FAILfailed to flash device

Once it's downloaded, place it in the Platform Tools folder inside ADT Bundle -> SDK. If you did everything right, you'll have fastboot and flash-all in the same directory.

For some reason when I install the android SDK (both times; tried reinstalling) I don't have any of the "flash" related files between "fastboot" and "hprof-conv" (see above in second picture). Any idea why this is happening? I'm running 64-bit windows 7. Thanks.

Besides normal booting of an android device, there are two more systems maintenance mode. The bootloader or fastboot mode and the recovery mode. We can get into both the modes via startup key combinations or by using adb commands.

Fastboot/recovery more (Summery)

Fastboot mode/recovery mode is mostly used to erase or install various images such as system, boot, userdata, and more. You may end up using fastboot tool and fastboot/recovery mode when you are installing a custom rom or restoring factory image on your android device.

Since you already de-/installed the driver several times, general adb / fastboot troubleshooting rules apply. Try different USB ports / cables, especially ports located away from the one you tried before, that might be connected to a different USB controller.

1 Yes I went to the store today and bought an expensive high throuput usbc to usba data cable. Since then at least I dont have the Code 10 for the driver anymore but now the drivers Android bootloader interface (active when phone is on fastboot) and Android composite ADV interface (active when phone is switched on normally) seem properly running.

I ran "fast boot flash boot", but it said "Waiting for device" and couldn't proceed.

The device was recognized as "Android download gadget" from the PC, so I tried to apply the following driver, but I could not install it.

-usb?hl=ja

Thank you for your support
