This is why we have a framebuffer / video driver framework in Barebox. We do not have a driver for MX35 yet, but that could of course be changed. On the other hand, I'm wondering why it needs 8 s until you see something on the Linux side. We have an MX35 system here which runs at 532 MHz, and it needs about 1 s from power-on into Linux userspace, so we decided to show the splash screen from there. rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
