在 ARM、RISC-V、PowerPC 以及大量国产化 SoC 平台中，Device Tree（设备树）已经成为 Linux BSP、驱动适配和板级 bring-up 的核心基础设施。很多系统研发工程师日常会改 DTS、排查 probe 失败、修 ...

嵌入式固件一般分为BootLoader和App，BootLoader用于启动校验、App升级、App版本回滚等功能，BootLoader在cpu上电第一阶段中运行，之后跳转至App地址执行应用程序。 因此，在发布固件的时候，会存在BootLoader固件和App固件；此时我们期望是将BootLoader固件和App固件合并 ...

One of the last things the Linux kernel does during system boot is mount the root filesystem. The Linux kernel dictates no filesystem structure, but user space applications expect to find files with ...

Freeing the way for independent Linux distributions to be installed on Windows 8 computers, the Linux Foundation has released software that will allow Linux to work with computers running the UEFI ...

Chinese companies have released a number of tiny devices designed to let you run Android apps on your TV over the past year or two. Some of the best models feature Rockchip RK3188 ARM Cortex-A9 ...

When the Linux Foundation announced that it was creating its own UEFI boot solution, it seemed that our woes about not being able to install Linux on Secure Boot systems would soon be coming to an end ...

A critical vulnerability in the Shim Linux bootloader enables attackers to execute code and take control of a target system before the kernel is loaded, bypassing existing security mechanisms. Shim is ...

There is a gaping security hole in the open-source bootloader shim that allows attackers – to inject their code in a man-in-the-middle position –, for example. A complete compromise of the systems is ...

Pressing the backspace key 28 times can bypass the Grub2 bootloader’s password protection and allow a hacker to install malware on a locked-down Linux system. GRUB, which stands for the Grand Unified ...

Linux shim, a small piece of code that many major Linux distros use during the secure boot process, has a remote code execution vulnerability in it that gives attackers a way to take complete control ...
