Falcon 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 a normal boot, with everything else kept the same. The short answer is about 3.8 s off the bootloader. The rest of this post shows where that time goes and where it doesn’t. This post stays at th...

Over 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. What made this journey truly rewarding wasn’t just getting the board up and running, but diving into the world of RISC-V for the first time. Through Yocto porting, I learned how OpenSBI (Open Supervisor Binary Interface) works, it...

Exciting news to share! Today, I reached my 100th contribution which is a significant milestone in my journey with the Yocto Project and OpenEmbedded. While my contribution may not be groundbreaking, I wanted to share my experience in the hope of helping those who are new to open-source contributions. First of all, I always had the desire of improving things and taking them to better places. T...
