Hi,
I am try to boot the 2.6.23-rc3 kernel to my custom board based on
8641D Processor. After uncompressing the kernel it was hang. I got the
following messages.
Uncompressing Kernel Image ... OK
Booting using flat device tree at 0x600000.
Then i tried to debug with GDB. In my source path i given the command
${CROSS_COMPILE}gdb vmlinux, I got GDB Prompt after i tried to set the
breakpoint at start_kernel. I got follwing messages
gdb) b start_kernel
Cannot access memory at address 0xc02b44ec
Processor Information:
8641D processor and the silicon revision is 2.0.
Part : MPC8641D
Revision: 2.0
e600 Core Revision: 2.2
DeviceMarking: B
Processor Version Register Value: 0x8004_0202
System Version Register Value: 0x8090_0120
I don't know how to proceed. Please tell the way how to start kernel
debug in this situation.

how are you connecting gdb to the board?
do you have a JTAG debugger connected to the board?

Hi,=20
Your flat device tree address seems too low. Try to move the dtb to
higher address such as 0x2000000.
And which version of your u-boot?
Cheers!

seems like a pretty old u-boot. Willing to try a 1.3.0-rc1?

If you can dump memory w/o connecting GDB, I suggest the following.
Look in your kernel build for System.map and grep for log_buf you
should get something like:
c040b04c d log_buf
c043b1a4 b __log_buf
then dump the memory @ these addresses. I can't remember which one
is the correct one. You'll want to subtract c000_0000 from the
address to get a physical address that you can dump. This should
help provide some possible insight into what's going on.

Yes, It's too old. Maybe not fully supports FDT. You can try the version
of Kumar said or in the BSP of Freescale released.

Hi,
I am not willing to upgrade the uboot. Becuase it takes some time to
port the new uboot for my custom boad.
whether the current problem is related to uboot ? One more point, previously
i tried 2.6.21 with the same uboot(1.1.6) we got linux prompt but we face
some issue in the pci express in that version. so we plan to upgrade the
kernel version.

I thought u-boot < 1.3 didn't understand the flat tree at all. In
which case you'll need a cuboot zImage.

Hi,
Sorry i specify the wrong version, we r using 1.2.0. This uboot
was taken from the BSP which was released by Freescale. Previously we tested
linux 2.6.21 kernel, we got linux prompt. For this we are using the same
uboot(1.2.0).
In that version we face some issues in the pci express, at that time kumar
suggest to upgrade the kernel verison 2.6.23-rc3.
Zhang did u suspect the problem is related to uboot?.

__log_buf is the actual buffer, log_buf points to the current insertion
point IIRC. It should be pretty obvious that you're looking at a dmesg
buffer though, unless there's nothing in there for some reason.

Hi, Sivaji,
I've tested the newest git tree of Paul's, which is aleady updated to
2.6.23-rc4. The kernel is no problem with the u-boot of our released BSP
(Jun, 2007) on MPC8641HPCN board.
Maybe you could update to the newest kernel git tree and try again.
Cheers!

Hi Zhang,
Asper ur idea, i downloaded latest BSP(Jun,2007) and the
kernel (2.6.23-rc4) from the Paul's Git tree.
Uboot(1.2.0) was taken from the latest BSP. I portted the new uboot to my
custom board, i got uboot prompt.
When i compiling the kernel i got following warning messages
WARNING: vmlinux.o(.text+0x169f6): Section mismatch: reference to
.init.data:boot_command_line (between 'note_bootable_part' and
'pmac_restart')
WARNING: vmlinux.o(.text+0x16a02): Section mismatch: reference to
.init.data:boot_command_line (between 'note_bootable_part' and
'pmac_restart')
WARNING: vmlinux.o(.text+0x16a12): Section mismatch: reference to
.init.data:boot_command_line (between 'note_bootable_part' and
'pmac_restart')
When i try to boot the kernel, I got following messages
Booting image at 00200000 ...
Image Name: Linux-2.6.23-rc4-g5326152f-dirty
Image Type: PowerPC Linux Kernel Image (gzip compressed)
Data Size: 1842307 Bytes = 1.8 MB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
Booting using flat device tree at 0x600000
I can't know whether the problem is related to uboot or
kernel. But i tested the board with the 2.6.21 kernel, it was up.In that
kernel we face some issues on PCI Express so we plan to upgrade the kernel.
But the latest kernel was not up.
Please advice me.
