Part 4: The Data Partition (dm-crypt and LUKS2) - Embedded Linux Security on the NXP FRDM i.MX93Part 3: The Root Filesystem (dm-verity) extended the chain of trust from the hardware root of trust to the root filesystem. The EdgeLock Enclave (ELE) authenticates the bootloader chain under AHAB,...

Part 3: The Root Filesystem (dm-verity) - Embedded Linux Security on the NXP FRDM i.MX93In Part 2: The Kernel (Signed FIT), we extended the chain of trust from U-Boot to the Linux kernel. U-Boot verifies the FIT configuration signature, then verifies the kernel and device tree against...

Part 2: The Kernel (Signed FIT) - Embedded Linux Security on the NXP FRDM i.MX93In Part 1: The Bootloader Chain (AHAB), we built the first part of the chain of trust. The Boot ROM loaded the ELE firmware, the ELE ROM authenticated the ELE firmware against NXP’s fused SRK hash ...

Part 1: The Bootloader Chain (AHAB) - Embedded Linux Security on the NXP FRDM i.MX93A device is only as trustworthy as the software it boots. If an attacker can replace the earliest boot software stored on the boot media, every later stage of the system can no longer be trusted be...

Falcon Mode on the FRDM-IMX93: what it changes and what it actually savesFalcon Mode is often described as a way to cut boot time. But how much does it actually save? I enabled it on an FRDM-IMX93 (Yocto BSP lf-6.18.2, image imx-image-core, eMMC) and compared it against...

Open-Source in Action: OrangePi RV2 (RISC-V) Now Supported in the Yocto ProjectOver the last weeks, I dedicated myself to adding support for the RISC-V based OrangePi RV2 SBC (Single Board Computer) to the meta-riscv layer in the Yocto Project. Curious about the implement... Jul 1, 2025 Embedded Linux, Yocto https://alperak.github.io/posts/orangepi-rv2-riscv-support-in-yocto-project/
OTA (Over-The-Air) UpdatesWhat is OTA (Over-The-Air) update? Over-the-air (OTA) means of remotely updating the firmware, software, operating system of a device over the internet connection.
