Bring-up with Netconsole and USB without a Serial Debug Net

Explore techniques for bringing up embedded systems without traditional serial debug consoles or JTAG in this 49-minute conference talk by Jason Kridner from Texas Instruments and BeagleBoard.org Foundation. Learn about utilizing Netconsole, USB, and Buildroot for bootloader and kernel development on designs lacking serial UART interfaces. Discover how to leverage bootloader-provided debug resources like EFI for the kernel. Follow along with demonstrations and reproduction materials using PocketBeagle boards and USB connections. Gain insights into topics such as Ethernet over USB, USB gadget concepts, NodeUSB, hardware testing, SOC support, and UART over USB. Understand the goals, challenges, and next steps in implementing these alternative bring-up methods for embedded systems development.
