In previous articles, we discussed the overall ecosystem of embedded Linux and provided a hands-on guide on how to compile firmware using Buildroot. This time, we will focus on how to use Buildroot to package custom software into the firmware. This article will first discuss the concept of the platform daemon and provide a simple … Read more
Due to current software limitations, the RISCV logic cannot share JTAG simultaneously. Therefore, if you want to debug both the logic and RISCV at the same time, you can achieve this through the RISCV’s soft JTAG. Soft JTAG is a software implementation of JTAG using GPIO. Here, we will demonstrate this using the TI60F225 DEMO. … Read more

Received feedback from many readers: “Clearly following the tutorial, but the STM32 board’s LED won’t light up?” This phenomenon hides hardware differences in embedded development that are easily overlooked, the connection method of the onboard LED and GPIO pins, is the most common “pitfall” for beginners transitioning from Arduino to STM32. Every line of code … Read more
