latest u-boot does add the chosen node.On Tue, Apr 08, 2008 at 03:50:26PM +0200, Andre Schwarz wrote:after building a debug kernel and attaching the bdi2000 it looks like the crash occurs during "console_init()" ...Does your device tree have a /chosen node after u-boot is done with it? find_legacy_serial_ports() can crash otherwise (we really should fix that).
that sounds promising ! Haven't seen this and will have a closer look.Since we're using a dtb I omit the "console=..." argument for the kernel. Is this correct ?It's OK if you have /chosen/linux,stdout-path.
ok.If "console=/dev/ttyS0,115200N8" argument is given the serial console stops working after console_init.... On other PowerPC system I could see something like this during boot : -> find_legacy_serial_port() stdout is /soc8568@e0000000/serial@4600 legacy_serial_console = 1 default console speed = 115340 <- find_legacy_serial_port() Should I see this message also ?Only if you enable debug messages in legacy_serial.c.
Yes - the log from the MPC8568 is a copy&paste from another posting. It's not my system.Have I misconfigured anything ?One thing that sticks out from the above is that you ask for ttyS0, but the stdout you list from the other system corresponds to ttyS1. Is this just a difference between the two systems?
I appreciate your help !-Scott
