U boot flash firmware

For one of our customers building a product based on i. MX6 with a fairly low-volume, we had to design a mechanism to perform the factory flashing of each product. The goal is to be able to take a freshly produced device from the state of a brick to a state where it has a working embedded Linux system flashed on it.

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. MX6 processors. It is therefore a very handy tool to recover i. MX6 platforms, or as an initial step for factory flashing: you can send a U-Boot image over USB and have it run on your platform. This tool already existed, we only created a package for it in the Buildroot build system, since Buildroot is used for this particular project.

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. 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. In order to make fastboot work in U-Boot, we modified the board configuration file to add the following configuration options:.

You can find the patch enabling fastboot on the Seco MX6Q uQ7 here: secomx6quq7-enable-fastboot. U-Boot enters the fastboot mode on demand: it has to be explicitly started from the U-Boot command line:.

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-loaderwe 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.

To reflash the contents of the rootfs partition with the rootfs. However, while using GPT partitioning is fine in most cases, i. MX6 has a constraint that the bootloader needs to be at a specific location on the eMMC that conflicts with the location of the GPT partition table. 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.Hi All, I think I have flash wrong u-boot image.

Is there any changes on it.? The big question is what exact versions of things you are talking about. You are correct. Our board as IT module. So i copy u-boot. But what exact BSP version are you talking about? One can't just mix and match u-boot. Have a look at the following article on our developer website detailing this as well.

But in V2. I suspect you are mixing later BSP binaries with earlier update scripts which won't quite work. Could you please first try with our latest stock BSP 2. Once that is confirmed working you may go about configuring, compiling and updating your custom U-Boot binary by adhering to above mentioned article.

When you turn on an embedded device such as a Chromebook, the firmware is the first software that runs. It sets up the machine so that it can load the operating system and then transfers control to the OS.

This general pattern applies to any architecture, but there are differences depending on the exact system architecture.

u boot flash firmware

On x86 systems, only the boot system is in SPI flash, and the firmware must deal with every aspect of setting up the machine. Typically, a first stage firmware such as Coreboot not covered in this guide is used on x86 to deal with these complexities. On x86, part of the firmware stays resident even after the OS runs, whereas on ARM and most other architectures, the firmware is no longer in memory once control transfers to the OS. The firmware sets up the basic peripherals such as the keyboard, display, mass storage, security chip TPMand SPI flash for its own use while it runs the steps to set up the machine.

In Chrome OS, the firmware can be updated, so the system first checks whether an update exists and, if so, it loads the update and jumps to execute it. In normal cases, the OS is available and is loaded and started. If a problem exists for example, the OS is corruptthe firmware enters recovery mode, which allows the user to insert media with a new OS. U-Boot Universal Boot is a useful basis for firmware because it has wide architecture support and contains many drivers and subsystems.
