Message-Id: <4DBF065C.3030407@freescale.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linuxppc-dev-uLR06cmDAlY/bJ5BZ2RsiQ@public.gmane.org, devicetree-discuss , linux-fbdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org I'm using a Freescale P1022DS (PowerPC e500 core) system, which has a built-in video controller. I have a framebuffer driver that works fine, and if I add "video=fslfb:1280x1024-32@60,monitor=0 console=tty0" to the command-line, then *most* of the kernel boot log appears on the serial port and the video display. However, the login prompt is always on the serial port. This happens even if I delete the "console=ttyS0,115200" from the command-line. I presume this is because the "linux,stdout-path" property in the device tree always points to a serial port node. So my question is: what do I need to do get the login prompt on the video console? That is, stdout goes to /dev/fb0 but stdin is still from /dev/ttyS0. I presume I need to direct "linux,stdout-path" to the fslfb node in the device tree, but there doesn't appear to be support for "linux,stdin-path". -- Timur Tabi Linux kernel developer at Freescale
