Using the Linux kgdb-kernel with the Walnut.

[Andrew H Pham]

Hi,

I am trying to boot up the Linux kgdb-kernel.2.4.18 on a Walnut board, but
it just freezes after it uncompressed the kernel.  Here is a screen shot:
"..
EMAC0 Ethernet Test OK.
ENET Speed is 100 Mbs...
FULL duplex connection
Booting from [ENET] Ethernet     ...
Sending bootp request ...


Loading file "//zImage" ...
Sending tftp boot request ...

zimage at:     004059DC 004A54DA
avail ram:     004AA000 02000000

Linux/PPC load: root=/dev/nfs
              ip=192.003.1.5:192.003.1.1::255.255.255.0:walnut:eth0:off
              nfsroot=192.168.1.1:/home/nfs/walnut
Uncompressing Linux...done.
Now booting the kernel
..."

And it just hangs.  I think this when it's waiting for input from the
              serial port 2 from the debugger then proceeds.  I hooked up
              an other session
of minicom to the second serial port on the Walnut, but only see garbages,
              "$S04#b7,..." .  I tried all the baudrates available and got
              different outputs or blank, all of which are
incomprehensible.

Has anyone got the Linux kgdb-kernel.2.4.18 to work with the Walnut board?

Any help would be appreciated,
Andy
