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 ...

最近在面试的时候问了不少嵌入式工程师一个问题：按下电源键到内核跑起来，中间发生了什么？大部分人的回答是：先运行Bootloader，再加载内核。 那内核加载到哪儿了？是加载到RAM里吗？为什么不直接从Flash里运行？MMU什么时候打开的？设备树是什么时候加载的 ...

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 ...

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 ...

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 ...

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 ...

Bootloaders are an essential bit of software for almost every modern electronic device. Unfortunately, any vulnerabilities in the bootloader can open a device up to attackers. Eclypsium researchers ...

Smart infrastructure vendor Nebulon today announced that its latest offerings provide newly hardened backups for configuration and snapshots, in an effort to add a new tool to the antiransomware ...
