Automatically booting our Linux You are probably be tired of using u-boot CLI to load the Linux FIT uImage into RAM and booting it manually. Surely, there must be something to be done to automate this... and you're right! Let's learn to do this! text/html 2025-08-06T18:03:47+03:00 http://ocw.cs.pub.ro/courses/ass/labs-2025/03/tasks/02?rev=1754492627&do=diff 02. Enabling networking on iMX93 Notice that the FRDM-iMX93 has two Ethernet ports. But if you boot your previous Buildroot distro and try to see the available network: ip link show, notice that they are missing. Instead, you'll only have the loopback interface lo. text/html 2025-08-06T20:04:02+03:00 http://ocw.cs.pub.ro/courses/ass/labs-2025/03/tasks/03?rev=1754499842&do=diff 03. Writing & packaging a GPIO app on Buildroot An embedded device is designed to interface with the physical world via sensors and actuators. The most common way to do this is by means of Generic Purpose Input/Output (GPIO): electrical connectors exposed by the SoC that can be freely controlled by software to be either input or output, read/write a logical signal (0-3.3/5V) with whatever they're connected too.
