Kim,

sorry for the general questions - but I'm running out of ideas. We never ever had that many problems getting a PowerPC running during=20 the past 10 years.

I've cross-checked the hardware and design with Freescale FAE.=20 Everything looks fine and is approved.

We're running latest u-boot v1.3.2 and kernel 2.6.25-rc8 from Denx.

A MPC5200B System is up and running fine with this scenario, so=20 hopefully there are no basic problems.

The MPC8343B (rev.3.1) is working pretty fine with u-boot including=20 mtest. Only problem is a the TSECs not working with our RGMII phy - but=20 this can wait.

I've set up a dts based on the MPC834x_mds and removed the 2nd PCI bus=20 and local bus stuff.
Kernel has been build with a new platform "MVBLM7" which is the name of=20 our board - nothing special so far.
u-boot fills out all parameters (clocks, mem, initrd @ chosen, ...)=20 correctly and the kernel is started exactly the same way as the MPC5200B=20 system using "bootm kernel_add initrd_addr dtb_addr".

Kernel starts and crashes with "unable to handle kernel paging request @=20 00000000".

After turning debug on in some files I can see that the initrd memory=20 gets reserved and the dtb is parsed correctly.
PCI memory/io spaces are set up fine.

At first I thought this is a problem with the device tree since the call=20 trace always points to "of_"-functions and "strcmp".
So I removed nearly everything from the kernel and dts including PCI,=20 net, USB and peripherals leaving only a minimum (cpu, mem, soc-node with=20 ipic and serial).

Unfortunately the error is still the same !

I wonder if there are some basic issues regarding MPC8343 or=20 specialities from the Freescale boards not being present on our board.

Major difference is the CPU (MPC8343B), 512MB RAM (using 2 BATs of=20 course) and nothing else on the local bus besides the Nor-Flash. Of course the MPC8343 has only a single PCI-32 and only one USB.

Do you have any hints on this ?
Do you suggest to wait for the 2.6.25 release ?
Do you know of any MPC8343 based boards already up and running ?

regards,
Andr=E9 Schwarz

Scott,

after building a debug kernel and attaching the bdi2000 it looks like the crash occurs during "console_init()" ...

Since we're using a dtb I omit the "console=..." argument for the kernel. Is this correct ?

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 ?
Have I misconfigured anything ?

u-boot prints the following dtb :

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).

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.

stdout is /soc8568@e0000000/serial@4600

Should I see this message also ?

Only if you enable debug messages in legacy_serial.c.

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?

latest u-boot does add the chosen node.
As far as I know it's for initrd setup ... don't know if it's complete.

Yes - the log from the MPC8568 is a copy&paste from another posting. It's not my system. I want ttyS0.

Scott,

I've added kallsyms and the #debug in legacy_serial.
Obviously there's missing something
-> see error "can't find stdout package /soc8343@e0000000/serial@4500 !" below.

Can you help here ?

Thanks,
Andre

Scott,

are you talking about a possible hardware problem or misbehaving code ?

Does it look like something gets overwritten during initrd extraction/movement ?

The system has 512MB RAM which means that we need 2 BAT regs to map the memory. I've found comments in Freescale u-boot header files that currently a max of 256MB is supported. I never understood why ? Could this problem be related to this ?

Do I need to supply reserved memory regions ? I thought u-boot is doing so for initrd and the kernel don't need it ...

I'll rebuild u-boot with 256MB memory size and do an extra run with memory test - just to make sure.

Any hints where to look else ?

regards,
Andre

Either. The same OF call is done in both places with the same argument, but is getting different results.

Kim's probably be the best one to answer u-boot questions.

are you talking about a possible hardware problem or misbehaving code ?

Either. The same OF call is done in both places with the same argument, but is getting different results.

Quoted 1 line

Does it look like something gets overwritten during initrd extraction/movement ?

Quoted 8 lines

Don't know.

The system has 512MB RAM which means that we need 2 BAT regs to map the memory. I've found comments in Freescale u-boot header files that currently a max of 256MB is supported. I never understood why ? Could this problem be related to this ?

Kim's probably be the best one to answer u-boot questions.

Scott + Kim,

as mentioned before I have re-built u-boot with the following modifications :

- Reduce Memsize from 512 to 256MB
- Skipped 2nd BAT setup

dtb looks the same but memory size set to 256MB.

System boots fine - this is weird !

I'm not really familiar with the powerpc tree of the kernel and far out of sync with the current development.

Could you have a look at this ?

Any ideas right now ?

Thanks,
Andre

MPC8343EA Linux DTS file

In reply to André Schwarz

Hi

We have an MPC8343EA based custom board.

I am not able to get Linux up and running in this. No serial output to debug further.
U-boot shows correct 'bdinfo' & 'clocks' output.

I doubt the DTS file in Linux. anyone has DTS file for MPC8343??

My current DTS file
/dts-v1/;

MPC8343EA Linux DTS file

In reply to André Schwarz

Hi

We have an MPC8343EA based custom board.

I am not able to get Linux up and running in this. No serial output to debug further.
U-boot shows correct 'bdinfo' & 'clocks' output.

I doubt the DTS file in Linux. anyone has DTS file for MPC8343??

My current DTS file
/dts-v1/;

We have an MPC8343EA based custom board.

I am not able to get Linux up and running in this. No serial output to debug further.
U-boot shows correct 'bdinfo' & 'clocks' output.

I doubt the DTS file in Linux. anyone has DTS file for MPC8343??

My current DTS file

well, for one, the dts you provide doesn't include a node for the ipic interrupt controller.

This is the entire DTS file:
/dts-v1/;

/ {
        model = "SC3000";
        compatible = "MPC8349EMDS", "MPC834xMDS", "MPC83xxMDS";

you don't mention the u-boot and kernel version numbers: does your linux kernel check for these compatibles? If yes, then use a debugger to find out exactly where else the kernel could be dying.
