Console: switching to colour frame buffer device 160圆4 To pick up the nouveau device driver, I added CONFIG_DRM_NOVEAU=y to the kernel defconfig file.Īlso, I can connect over serial to the real target, by adding console=ttyS0,115200 to the kernel parameters in the pxelinux.cfg/default's "append" line. The only difference in the Buildroot config between the virtual target and this real target is the Gallium nouveau driver (which supports all nVidia cards), under Target packages -> Graphics libraries and applications -> mesa3d. Except for updating Buildroot to the latest stable release (2015.02), I'll pick up from where I left off. In a previous blog, I demonstrated an NFS booted Buildroot distribution for this Intel Core2 Duo Dell PC. Since I am an embedded SW engineer, I treat even the PCs like targets (rather than desktops). Quadro NVS 420 is supported under the NV50 Tesla family, code name NV98 (G98), as you can see on this page.īuildroot config for Qt5, OpenCV, and nVidia Quadro 420 GPU Maybe a better alternative is to pick up an open source driver from the noveau project. The X server requirement is a deal-breaker for me: I want to keep the embedded distribution small. Now to the fine prints, from the driver README file: X is required, and glibc >= 2.0 is required.
openssh: necessary to connect to the target from gdb on the server.OpenGL: OpenGL ES 2.0 and opengl module.Gallium swrast (software OpenGL) driver.
I changed x86_64_defconfig from the to create /home/henry/圆4/BR2/nfig Using a custom-as supposed to in-tree-(def)config file: I need to add a couple of options for the NFS rootfs.Register toolchain within Eclipse Buildroot plug-in.Build cross gdb for the host: does NOT build on the vbox server for some reason.enable ccache, but change the cache location to within the Buildroot directory (to avoid saving to the virtual HDD, and keep all work in the Vbox shared folder): $(TOPDIR)/.buildroot-ccache.Target options: x86_64, corei2 (core7 selects SSE4 features, which Virtualbox does NOT support yet).
