We go to RPI’s GIT page (see 12) and see that there are no different versions of bootcode.bin available. We either try different versions of the bootcode.bin files, or we try to change the files that are run by bootcode.bin. Because bootcode.bin is closed-source, we can’t configure it directly so there are 2 things we can do. In this part, the software embedded into the device by the manufacturer runs the bootcode.bin. K5 - Application (Qt QML) K1 - Raspberry boot stage K2 - Linux pre-boot stage (3rd Stage Bootloader) (start.elf, bcm2710-rpi-3-b.dtb) K1 - Raspberry boot stage (1st & 2nd Stage Bootloader) (bootcode.bin) RPI boot process from power-up to Qt application is as the following dtb -> read cmdline.txt -> kernel.img runs

Basic logic: power-up the RPI -> embedded software inside RPI runs -> bootcode.bin runs -> start.elf runs -> read config.txt -> read.

After Kernel runs, we have full control over everything.

kernel.img: This is the Linux Kernel, run by start.elf.

After performing these operations, it’ll keep running on the device as a GPU driver till the device is turned off. dtb file, and run the kernel.img with the parameters in the cmdline.txt file. Its purpose is to split RAM between the GPU and the CPU, apply the settings inside the config.txt file to the GPU, make the necessary adjustments by reading the corresponding.

start.elf: This is the 3rd Stage Bootloader run by bootcode.bin.

It contains hardware descriptions of the device, like GPIO pins, display ports, etc.

cmdline.txt: Contains the Kernel parameters that will be passed to the Kernel when executing it.

config.txt: Contains the GPU settings.

Its purpose is to run start.elf (3rd Stage Bootloader).

bootcode.bin: This is the 2nd Stage Bootloader, which is run by the 1st Stage Bootloader which is embedded into the RPI by the manufacturer.

The files related to RPI’s boot process and their purposes are briefly as the following

Qt (QML) application shall automatically be started.

Buildroot shall be used for Linux customization.

That is why the most difficult parts of the RPI boot optimization process are SoC-related ones. (see 2) So we cannot customize them without reverse engineering. Therefore, SoC-related softwares are provided to us as binary. RPI uses Broadcom’s closed-source chip as System on Chip (SoC). I recommend that you dig into more on this topic on the internet. RPI’s boot process is based on GPU rather than CPU.

The boot process of RPI is kind of different from the other, traditional devices. Besides that, optimizations should be done and tested one by one, so that the effect can be seen. We need to be able to answer questions such as what is the boot sequence of the device, which files are running in which order to boot the device, which files are 100% required etc. If you previously installed it at the system level and now want it to be only the current user (or vice versa), it will not remove it, you have to do it yourself.First of all, we should know the target device well since some critical stages of the boot optimization process are low-level (hardware dependent). If you have an older Google USB driver installed, please uninstall it from the Control Panel before installing fresh

If you have a driver enumeration problem in Windows 8.1, install update KB2917929 If the installation fails, post here the contents of “ADB-installer.log” from your desktop. If anyone has trouble detecting the device, go to the images directory and view the attached howto_driver.zip file The installer automatically decides whether to install 32-bit or 64-bit drivers. System-wide: ADB and Fastboot are installed to the %SystemDrive%\adb directory, and a system-wide path is added.Ĭurrent User Only: ADB and Fastboot are installed to the %UserProfile%\adb directory, and a path is added for the current user.ĬMD can use ADB and Fastboot from any directory.ĭrivers are installed on the system – no need to install them from directories.

Press Y/Yes to install drivers or N/No to skip.Press Y/Yes to install ADB on a system level or N/No for current user only.Press Y/Yes to install ADB and Fastboot or N/No to skip.Run it (requires administrator privileges).

It is a very small and fast installer of tools and drivers.įast – 15-second install (many times even less)ĪIO – ADB and Fastboot as well as driversĮasy to install – just run it and the program will guide youĬlean – ADB and Google drivers from the latest SDK I saw another ADB installer on XDA, but it wasn’t good enough for me so I finally posted it here. I originally made it for my Kurdish friend AnGrY DuDe in early 2013. No need to download a large SDK for 3 small things. This is an All-in-One installer of 3 essential tools for PC for Android.
