Hello, I have an embedded system with an on-board processor powerpc
MPC5200B
and Linux kernel 2.6.22,
I must turn over to MMC SPI on the PSC6.
First, I
have enabled PSC6:
in ../arch/ppc/platforms/lite5200.c added PSC6 in SPI mode
struct mpc52xx_psc_func mpc52xx_psc_functions[] = {
{ .id = 3,
.func = "uart",
},
{ .id = 4,
.func = "uart",
},
{ .id = 5,
.func = "spi",
},
};
in ..
/arch/powerpc/boot/dts/lite5200b.dts enabled PSC6 in SPI mode
// PSC6 in spi mode example
spi@2c00 { // PSC6
device_type = "spi";
compatible = "mpc5200b-psc-spi\0mpc5200-psc-spi";
cell-index = <5>;
reg =
<2c00 100>;
interrupts = <2 4 0>;
interrupt-parent = <&mpc5200_pic>;
};
Now on the menuconfig enabling these options:
$ make ARCH=powerpc
CROSS_COMPILE=powerpc-linux-gnu- menuconfig
Platform support --->
[*]
MPC5200 (L25R) bugfix support
[*] Freescale Lite5200 Eval Board
Device
Drivers ---> SPI Support --->
[*] SPI support
<*> Freescale MPC52xx
PSC SPI controller
this options settings the CONFIG_SPI_MPC52xx_PSC=y variable
into .config
When linux booting, if I debug ../driver/spi/mpc52xx_psc_spi.c,
see that:
bus platform: add driver mpc52xx-psc-
spi
bus platform: remove driver mpc52xx-psc-spi
drivers/spi/mpc52xx_psc_spi.c:
of_register_platform_driver failed (-19)
why??
any idea??
Someone knows how
to enable mmc over spi on PSC6?
thanks Fabio

You're using arch/ppc which is depreciated. You should move to using
arch/powerpc (set ARCH=powerpc when compiling). Devices are then
enabled in the device tree source file
arch/powerpc/boot/dts/lite5200b.dts.
Many things have changed with MPC5200 support in the last year, you
should also use the latest kernel release (2.6.25.2 when it is
released. If you use 2.6.25.1, then there is a trivial bug in the psc
serial port driver that you'll need to fix. I'll include the link to
the patch below)
Cheers,

I've tried to port my exesting configurations to the powerpc tree but
some configurations files are missing.
I need to set PSC3 - PSC4 in uart mode:
before in file *arch/ppc/platforms/lite5200.c* I added
struct mpc52xx_psc_func mpc52xx_psc_functions[] = {
{ .id = 3,
.func = "uart",
},
{ .id = 4,
.func = "uart",
},
{ .id = -1, /* End entry */
.func = NULL,
}
};
I need to set PSC4 as a low level debug: *
*before in file *arch/ppc/platforms/lite5200.h *I added
#define MPC52xx_PF_CONSOLE_PORT 4 /* PSC4 */
Finally I need to set the virtual memory translation on a range of 128 MB:
before in file *arch/ppc/kernel/head.S *I added
/*ori r11,r11,BL_128M<<2|0x2 set up BAT registers for 604 */
ori r11,r11,BL_128M<<2|0x2 /* set up BAT registers for 604 */
could you please explain me how to do the same operations in powerpc tree??
thanks Fabio

First, create a new .dts file for your board in arch/powerpc/boot/dts.
(just copy the lite5200.dts file). Modify the .dts to have your
board's name (in the form "<vendor>,<boardname>") in the compatible
and model properties.
Next, add your boards name to the list of boards in
arch/powerpc/platforms/52xx/mpc5200_simple.c.

Edit your boards .dts file and uncomment PSCs 3 and 4. Comment out
PSC1 if you aren't using it.

I don't think we have any early debug enabled yet in arch/powerpc for
the mpc5200.

New file is arch/powerpc/kernel/head_32.S. I don't think that is the
cleanest way to do it though. Why do you need to change the BAT
mapping from 256 to 128?

Ok, maybe it's better to start from the beginning.
Now I'm using a Lite5200b board, just to avoid problems with my
hardware, and I'm trying to have a bootable kernel.
With kernel version 2.6.24.6 I do the following commands
$ make ARCH=powerpc lite5200_defconfig
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- uImage
then I copy the arch/powerpc/boot/uImage and a rootfs.uimage on the
board, but uBoot stops at the beginning:

Right; some concepts need to be explained now... There is a major
difference between arch/ppc and arch/powerpc. In arch/ppc, the kernel
is hard coded with the list of devices in the system. In
arch/powerpc, the list of devices is captured in a data structure
called the Flattened Device Tree (FDT). fdt data structures are
generated from the .dts (device tree source) files in
arch/powerpc/boot/dts/.
When you build a uImage with arch/ppc, you get a hard coded kernel
that works with u-boot: "bootm <kernel_addr> <ramdisk_addr>"
When you build a uImage with arch/powerpc, you get a dynamic kernel
that needs to be passed the device tree blob on boot. Newer u-boot
supports dts booting: "bootm <kernel_addr> <ramdisk_addr> <dt_addr>"
or "bootm <kernel_addr> - <dt_addr>" if you're not using a ramdisk.
However, if you've got an older u-boot version installed on your
board, you need to create an image that binds the device tree into the
kernel image. This is called a "cuImage". So, instead of doing "make
ARCH=powerpc uImage", you should do "make ARCH=powerpc
cuImage.<boardname>". This 'wraps' the kernel with a boot wrapper
that includes the device tree blob but maintains compatibility with
the old style uImage format.
For example, use "make ARCH=powerpc cuImage.lite5200b" to build an
image for the lite5200b board. The build scripts will use the
lite5200b.dts file in the dts directory for building the image. If
you add "fabios-fantastic-board.dts" to arch/powerpc/boot/dts, then
you can build "cuImage.fabios-fantastic-board". :-)

ARCH=ppc and ARCH=powerpc are completely different beasts. Forget
that you even know about ARCH=ppc for this entire exercise.

Hello!
I've seen you guys are playing with a Lite5200b board, so I've decided
to do another attempt with mine.

If I'm not wrong, the right sequence of commands should be the following:
$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
... [customizations]...
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- cuImage.lite5200b

I've looked at Load Address and Entry Point of the cuImage and it
sounds a little strange to me that these values are not zero, so I've
manually changed them both to 0x00000000 using mkimage, but the
result is always the same: no boot at all.

By the way, Grant, you seem to be very expert in making a kernel with
ARCH=powerpc. Can you tell me how to find some docs to improve my
knowledge in this field? I've found something interesting in
Documentation/powerpc, but they are not too explicative about the
differences between PPC/Powerpc building, and about how to make the
last one.

Oh, and the fix I told you about (fixing the unterminated list) didn't
make it into 2.6.25.2. You still need to manually apply it. It
should be in 2.6.25.3.

Doesn't look like you are passing a kernel parameters line. The
kernel probably is booting, but doesn't know where to output the
console. Try adding "console=ttyPSC0,115200".

Hello,
in uboot i have setting the bootargs variable:
=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> saveenv
If I'm not wrong, the right sequence of commands should be the following:
$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
.. [customizations]...
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- cuImage.lite5200b
and this is the output:
..
CHK include/linux/version.h
CHK include/linux/utsrelease.h
CALL scripts/checksyscalls.sh
CHK include/linux/compile.h
CALL arch/powerpc/kernel/systbl_chk.sh

Hi Grant,
I've tried to add that with this commands
=> bootargs debug console=ttyPSC0,115200 root=/dev/ram
=> saveenv
but the result is not so different. It still stops after printing these lines
>Linux/PowerPC load: debug console=ttyPSC0,115200 root=/dev/ram
>Finalizing device tree... flat tree at 0x75e300
What should I see after that, in case of successful boot?
Thanks for your help.

To: linuxppc-embedded
Hello, I have an embedded system with an on-board processor powerpc MPC5200B
and Linux kernel 2.6.22,
I must turn over to MMC SPI on the PSC6.
First, I
have enabled PSC6:
in ../arch/ppc/platforms/lite5200.c added PSC6 in SPI mode
struct mpc52xx_psc_func mpc52xx_psc_functions[] = {
{ .id = 3,
.func = "uart",
},
{ .id = 4,
.func = "uart",
},
{ .id = 5,
.func = "spi",
},
};
in ..
/arch/powerpc/boot/dts/lite5200b.dts enabled PSC6 in SPI mode
// PSC6 in spi mode example
spi@2c00 { // PSC6
device_type = "spi";
compatible = "mpc5200b-psc-spi\0mpc5200-psc-spi";
cell-index = <5>;
reg =
<2c00 100>;
interrupts = <2 4 0>;
interrupt-parent = <&mpc5200_pic>;
};
Now on the menuconfig enabling these options:
$ make ARCH=powerpc
CROSS_COMPILE=powerpc-linux-gnu- menuconfig
Platform support --->
[*]
MPC5200 (L25R) bugfix support
[*] Freescale Lite5200 Eval Board
Device
Drivers ---> SPI Support --->
[*] SPI support
<*> Freescale MPC52xx
PSC SPI controller
this options settings the CONFIG_SPI_MPC52xx_PSC=y variable
into .config
When linux booting, if I debug ../driver/spi/mpc52xx_psc_spi.c,
see that:
bus platform: add driver mpc52xx-psc-
spi
bus platform: remove driver mpc52xx-psc-spi
drivers/spi/mpc52xx_psc_spi.c:
of_register_platform_driver failed (-19)
why??
any idea??
Someone knows how
to enable mmc over spi on PSC6?
thanks Fabio Tosetto
