Kernel hangs on EP862-1.1 during boot

Kernel hangs on EP862-1.1 during boot

[Jan Dominik Baranski]

Hello all,
I'm having trouble getting a 2.4.22 kernel to boot on an Embedded Planet
EP862-1.1 board (based on an MPC860). I get this:
---
Loaded addresses 00400000 through 0049FFFF.
 >go
[Go 00400000]

loaded at:     00400000 004A31F4
relocated to:  00180000 002231F4
board data at: 00220128 00220144
relocated to:  001862E0 001862FC
zimage at:     001868A0 0021F3EC
avail ram:     00224000 01000000

Linux/PPC load: console=ttyS0,9600
Uncompressing Linux...done.
Now booting the kernel

<just hangs here>

---
I've searched the archives, but no one seems to have this board/problem
combination. I've made sure the watchdog timer is disabled and that the
IMMR (0xfa200000) is set correctly. Being pretty new to this, I don't
really know where else to look. Maybe something related to m8xx_board_info?

The thing is, I've been able to get an old kernel (2.4.7) from Timesys
that's configured for an RPX Classic board to boot correctly. I just
can't figure out what they may have done that I haven't.

Any suggestions??

Thanks

-Jan

Hi Jan,

What you could do is check of your board data that is passed to the kernel
is still valid in start_kernel.
Also, are you sure you have the kernel uart driver properly configured
(i.e. it works but you don't see anything)

I got the linuxppc_2_4_devel tree at http://ppc.bkbits.net/ to boot with no
problem.  The compiler I used was ELDK.  The config file was
arch/ppc/configs/rpxcllf_defconfig.

Thanks for the help. Until some of you mentioned it, I didn't even think
the linuxppc kernels were any different from the kernel.org
kernel+patches. After some wrestling with BitKeeper, I've got
linuxppc_2_4_devel working great.

Thanks again
