2.5 bk tree on 8xx board ... so close

2.5 bk tree on 8xx board ... so close

[Robert P. J. Day]

   after messing with the kernel config of the latest "bk pull", and
building a new kernel and ramdisk, i got:

RAMDISK: Compressed image found at block 0
VFS: Mounted root (ext2 filesystem).
Mounted devfs on /dev
Freeing unused kernel memory: 60k init
Configuring localhost networking ...
SIOCSIFADDR: No such device   (ignore, i tried to configure eth0)
Mounting /proc filesystem ...
Mounting /tmp filesystem ...
There are no /dev/mtdblock devices here, aborting.  (no, not really)
Clearing /var/log/msgs and starting syslogd ...
I found portmap, so I'll start it now ...
I found telnetd, so I'll start it now ...
Bailing for testing purposes.


BusyBox v1.00-pre10 (2004.06.24-

... and hang.

so, from the above, i got

1) localhost networking configured
2) /proc mounted
3) /tmp (tmpfs) mounted
4) syslog, portmap and telnet starting
5) an exit from the startup script since i wanted to keep things
    simple

at that point, /etc/inittab has the line:

::respawn:-/bin/sh

/bin/sh being, of course, a link to busybox.  i'm not sure what to
make of the partial output, perhaps some problem with the serial or
console port that the shell is trying to use.  so i guess it's on to
poking around the console port, see if that's the issue.

getting so close ...

Which serial driver did you use?  For me 8xx_UART does not work, but
CPM_UART will (it's still not quite correct, I have to config in both
SMC1 and SCC1 to get SMC1 to work, but I'm burried under a bunch of
other stuff right now).

i was, in fact, using 8xx_UART under the "MPC8xx CPM options" menu,
but (pardon my confusion) i'm not aware of this CPM_UART option of
which you speak (unless you're just paraphrasing).

if i deselect 8xx_UART, i'm assuming you're talking about going then
to the menu selections:

   Device Drivers
     Character devices
       Serial drivers

and selecting the appropriate CONFIG_SERIAL_CPM* settings (_SCC1 and
_SMC1)?  is that what you're referring to above?

   i may have to wait for one of the board experts to get in later to
make sure i have the right settings here.  thanks so far.

Paraphrasing from memory, yes, sorry.

Yes, that driver.  As I was saying, for some reason I haven't had time
to dig into, I have to select both SCC1 and SMC1 to get a console which
is on SMC1 working.  I've also found that enabling everything doesn't
horribly kill the board, so you could just try that for now.
