It is possible to adapt the kernel build scripts for the Xtensa architecture to create a self-booting image. See Download and Run the Kernel for an example. It can then load and execute a Linux RAM image (Image.elf or vmlinux) onto the target using standard GDB commands. For example, Tensilica Tools GDB (xt-gdb) can connect to a target Xtensa processor using OCD via the Xtensa OCD Daemon. One common way to load a Linux kernel is to use debugging interfaces such as On-Chip Debug (OCD). For more details, see the tarball's README.txt file.Īn alternative to boot loaders is an external (e.g.

For an example of how to boot the Linux kernel using RedBoot on the LX60 or LX200 boards, see RedBoot Example.Ī source tarball for RedBoot with support for the Xtensa architecture is available here. For more information and to request sources, please contact Tensilica directly. See the relevant board documentation from Tensilica for more details such as usage and supported features. A RedBoot binary targeting the XTAV60 (LX60) or XTAV200 (LX200) emulation board is usually provided after generating an FPGA bitstream for one of these boards. Tensilica has also ported RedBoot for the Xtensa architecture. A very complete U-Boot manual is also available here.Īs of release v2016.09 xtensa support is available in the U-Boot mainline. It has a very complete Project Page as well as an nice introduction available here. U-Boot is one of the most popular boot loaders for Linux. Ive compiled Xen package from aur without problems, and Ive also compiled as usually custom kernel with xen support as is written in arch wiki pages. I have a suitable processor, with vmx support. Most boot loaders today provide additional features that allow to upgrade the firmware and access the system for troubleshooting. Hi I want to setup Xen 4.1.1 with HVM support. The bootstrap loader or boot loader is a small program running on a computer or device after power-on to load the operating system. 2 U-Boot (build instructions for Xtensa).
