Do you mean zImage.embedded? I have been using make_image utility from uboot and using image arch/ppc/boot/images/vmlinux.gz to create image that uboot downloads via tftp. > >> My console does display everything properly running u-boot >but once >> the >> control goes to linux don't see anything on the console. >> > >Did you happen to customize the BAUD rate information for u-boot or >Linux?

If I attach the BDI it is looping in serial_console_write. I did verify that clock rate is getting passed from uboot to kernel correctly. In uboot I am not setting the variable clock_in_mhz. Doea anybody have .config file for EP8260 that I can use? -Kiran ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
