Linux on Motorola LoPEC


Hi!

I have a Motorola PPC-board. It is the LoPEC-P011 with PPC5-Bug version
1.3. The board has only a network connection an no hard disk or flash
memory.

Now, I want run Linux on it. My idea is to load the bootloader with tftp
und mount the filesystem with nfs. The problem is, that I cannot find
any working bootloader. I tried ppcboot, but there is no config for the
LoPEC.

Do anyone know a installtion guide for this board? Or is there a working
bootloader and kernel?

IRQ0 handler


Hi,

Can anybody tell me how to install a handler for irq0 on an 8xx
platform? Doing the obvious (request_8xxirq (SIU_IRQ0 ...)) doesn't seem
to work. It seems that I need to modify head_8xx.S so that the excption
handler for 0x100 is do_IRQ instead of UnKnownException. I tried the
patch below, but now I get a Software Emulation trap (0x1000). Any help
gratefully accepted.

Chris.

/* System reset */
#ifdef CONFIG_SMP /* MVME/MTX start the secondary here */
    STD_EXCEPTION(0x100, Reset, __secondary_start_psurge)
#else
/****
    Replace norrmal NMI handler with do_IRQ

    STD_EXCEPTION(0x100, Reset, UnknownException)
****/
NMI_Interrupt:
    EXCEPTION_PROLOG;
    addi    r3,r1,STACK_FRAME_OVERHEAD
    li    r20,MSR_KERNEL
    li    r4,0
    bl    transfer_to_handler
    .long    do_IRQ;
    .long    ret_from_intercept

RE: mic2563 dual slot pcmcia controller


Can somebody point to a similar driver code, to control mic2563, which is
memory mapped on mpc8xx board, with cs#4 as chip select? Any template driver
code would be helpful as well.

I have 2.4.18 kernel, and is booted by u-boot 0.4. However, I do not think
that I should do any init of pcmcia controller from the u-boot, because
u-boot does not use it and hence should not init it. I want to init it
inside the kernel. I thought m8xx_setup.c and m8xx_pcmcia.c is a better
place to do all my chip select for controlling mic2563 and the other pcmcia
related settings.

I think what you mean is that you want to load the zImage (compressed
kernel + arch/ppc/boot/... bootwrapper [+ initrd]) and mount the root
filesystem via nfs.

That board should have come with working firmware.  Did it get erased or
something?  If so, you should be able to get a fw binary from Morotola.

Look on the MOT website.

DINK32 R13.1 on Sandpoint X2


Hi,all,
    Now I'm working on a Motorola Sandpoint X2 board with ppc8240.
I use DINK32 r13.1 to boot my linux kernel image.
    From DINK32 r13.1 user manual,I know that DINK32 r13.1 supports
ethernet card Realtek 8139,but after these steps:
       DINK32[MPC8240] {7} >>ni -i
        some configrations......

       DINK32[MPC7455] {8} >>ni
       NETWORK INFORMATION
            PCI CARD
            Type 8139/10EC on slot 16
            SETTINGS
            SERVER(TFTP) : 10. 18.15.27
            GATEWAY : 10. 18.15.254
            NETMASK : 255.255.255. 0
            DHCP : 0. 0. 0. 0
            CLIENT(DINK) : 10. 18.15.201
            DHCP: Disabled
            SESSION TIMEOUT: Never

 Then I reset the system,but the Tealtek 8139 seems not to work correctly!:(
 I ping the board from my host computer with OS Redhat linux 9.0,but I can't
 get any response!
 Can anyone help me?

Memory Profiling Tool


Is there any memory profiling and leak detection tool available which works
for both PPC and X86??

Thanks.

Ravi.

mpc8xx CPM timer usage


Greetings

Does anyone know of any 'standard' Linux drivers that make use of any of
the 4 CPM timers?

I just want to check before the hardware guys caste our i/o lines into
stone :-))

Many thanks

Here's what I know about.
1. There's a utility built into glibc which may be of some help:
http://www.gnu.org/manual/glibc-2.2.5/html_node/Allocation-Debugging.html#Allocation%20Debugging
but it's a bit minimal.

2. x86 only - valgrind, of course.  God's gift to x86 programmers.  Shame
it's not been ported to ppc.

3. libmudflap.  This is very promising; see
http://people.redhat.com/dnovillo/Papers/nordu2003-slides.pdf
http://www.linux.org.uk/~ajh/gcc/gccsummit-2003-proceedings.pdf
However, it's part of the SSA branch of gcc-3.4, so you'll need to use
something like http://kegel.com/crosstool to build it.
I am hoping to try this out on ppc sometime, but haven't yet.
FWIW, it's provided with Red Hat's taroon beta, so it must
be getting close to usable.

If you're debugging c++, you should also read
http://gcc.gnu.org/onlinedocs/libstdc++/debug.html

When I used the DENX ELDK kernel on a custom MPC8XX board with serial
lines and Ethernet mostly, I once found no driver *used by the project*
that used the CPM timers. Note that we wrote our own SPI bus code,
though.

Your best bet is to check arch/ppc/8xx_io/*.[chS].

Why bother, since anyway they'll cast them the wrong way around?
