Notes for the Qemu MIPS port
|
||||
----------------------------
|
||||
|
||||
I) Example usage:
|
||||
|
||||
# ln -s u-boot.bin mips_bios.bin
|
||||
start it:
|
||||
qemu-system-mips -L . /dev/null -nographic
|
||||
|
||||
or
|
||||
|
||||
if you use a qemu version after commit 4224
|
||||
|
||||
create image:
|
||||
# dd of=flash bs=1k count=4k if=/dev/zero
|
||||
# dd of=flash bs=1k conv=notrunc if=u-boot.bin
|
||||
start it:
|
||||
# qemu-system-mips -M mips -pflash flash -monitor null -nographic
|
||||
|
||||
2) Download kernel + initrd
|
||||
|
||||
On ftp://ftp.denx.de/pub/contrib/Jean-Christophe_Plagniol-Villard/qemu_mips/
|
||||
you can downland
|
||||
|
||||
#config to build the kernel
|
||||
qemu_mips_defconfig
|
||||
#patch to fix mips interrupt init on 2.6.24.y kernel
|
||||
qemu_mips_kernel.patch
|
||||
initrd.gz
|
||||
vmlinux
|
||||
vmlinux.bin
|
||||
System.map
|
||||
|
||||
4) Generate uImage
|
||||
|
||||
# tools/mkimage -A mips -O linux -T kernel -C gzip -a 0x80010000 -e 0x80245650 -n "Linux 2.6.24.y" -d vmlinux.bin.gz uImage
|
||||
|
||||
5) Copy uImage to Flash
|
||||
# dd if=uImage bs=1k conv=notrunc seek=224 of=flash
|
||||
|
||||
6) Generate Ide Disk
|
||||
|
||||
# dd of=ide bs=1k cout=100k if=/dev/zero
|
||||
|
||||
# sfdisk -C 261 -d ide
|
||||
# partition table of ide
|
||||
unit: sectors
|
||||
|
||||
ide1 : start= 63, size= 32067, Id=83
|
||||
ide2 : start= 32130, size= 32130, Id=83
|
||||
ide3 : start= 64260, size= 4128705, Id=83
|
||||
ide4 : start= 0, size= 0, Id= 0
|
||||
|
||||
7) Copy to ide
|
||||
|
||||
# dd if=uImage bs=512 conv=notrunc seek=63 of=ide
|
||||
|
||||
8) Generate ext2 on part 2 on Copy uImage and initrd.gz
|
||||
|
||||
# Attached as loop device ide offset = 32130 * 512
|
||||
# losetup -o 16450560 -f ide
|
||||
# Format as ext2 ( arg2 : nb blocks)
|
||||
# mke2fs /dev/loop0 16065
|
||||
# losetup -d /dev/loop0
|
||||
# Mount and copy uImage and initrd.gz to it
|
||||
# mount -o loop,offset=16450560 -t ext2 ide /mnt
|
||||
# mkdir /mnt/boot
|
||||
# cp {initrd.gz,uImage} /mnt/boot/
|
||||
# Umount it
|
||||
# umount /mnt
|
||||
|
||||

|
||||
|
||||
10) Now you can boot from flash, ide, ide+ext2 and tfp

||||
# qemu-system-mips -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
|
||||
|
||||
II) How to debug U-Boot
|
||||
|
||||
In order to debug U-Boot you need to start qemu with gdb server support (-s)
|
||||
and waiting the connection to start the CPU (-S)
|
||||
|
||||
# qemu-system-mips -S -s -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
|
||||
|
||||
in an other console you start gdb
|
||||
|
||||
1) Debugging of U-Boot Before Relocation
|
||||
|
||||
Before relocation, the addresses in the ELF file can be used without any problems
|
||||
by connecting to the gdb server localhost:1234
|
||||
|
||||

2) Debugging of U-Boot After Relocation
|
||||
|
||||
For debugging U-Boot after relocation we need to know the address to which
|
||||
U-Boot relocates itself to 0x87fa0000 by default.
|
||||
And replace the symbol table to this offset.

PART 3)
|
||||
Setting up the BDI2000, and preparing for TCP/IP network comms:
|
||||
|
||||
Connect the BDI2000 to the PC using the supplied serial cable.
|
||||
Download the BDI2000 software and install it using setup.exe.
|
||||
|
||||
[Note: of course you can also use the Linux command line tool
|
||||
"bdisetup" to configure your BDI2000 - the sources are included on
|
||||
the floppy disk that comes with your BDI2000. Just in case you don't
|
||||
have any Windows PC's - like me :-) -- wd ]
|
||||
|
||||
Power up the BDI2000; then follow directions to assign the IP
|
||||
address and related network information. Note that U-Boot
|
||||
will be loaded to the Sandpoint via tftp. You need to either
|
||||
use the Abatron-provided tftp application or provide a tftp
|
||||
server (e.g. Linux/Solaris/*BSD) somewhere on your network.
|
||||
Once the IP address etc are assigned via the RS232 port,
|
||||
further communication with the BDI2000 will happen via the
|
||||
ethernet connection.
|
||||
|
||||
PART 4)
|
||||
Making a TCP/IP network connection to the Abatron BDI2000:
|
||||
|
||||
Telnet to the Abatron BDI2000. Assuming that all of the
|
||||
networking info was loaded via RS232 correctly, you will see
|
||||
the following (scrolling):
|
||||
|
||||
- TARGET: waiting for target Vcc
|
||||
- TARGET: waiting for target Vcc
|
||||

|
||||
Power up the target Sandpoint:
|
||||
If the BDM connections are correct, the following will now appear:

|
||||
Using a crossover serial cable, attach the PC serial port to the
|
||||
Sandpoint's COM1. Set communications parameters to 8N1 / 9600 baud.
|
||||

|

|

1. Showing activity
|
||||
|
||||
U-Boot for the OXC board can show its current status using
|
||||
the Active LED. This feature is configured by the following
|
||||
options:
|
||||
|
||||
CONFIG_SHOW_ACTIVITY
|
||||
|
||||
When this option is on, the Active LED is blinking fast
|
||||
when U-Boot runs in the idle loop (i.e. waits for user
|
||||
commands from serial console) and blinking slow when it
|
||||
downloads an image over network. When U-Boot loads an image
|
||||
over serial line the Active LED does not blink and its state
|
||||
is random (i.e. either constant on or constant off).
|
||||
|
||||
CONFIG_SHOW_BOOT_PROGRESS
|
||||
|
||||
When this option is on, U-Boot switches the Active LED
|
||||
off before booting an image and switches it on if booting
|
||||
failed due to some reasons.

PART 3)
|
||||
Setting up the BDI2000, and preparing for TCP/IP network comms:
|
||||
|
||||
Connect the BDI2000 to the PC using the supplied serial cable.
|
||||
Download the BDI2000 software and install it using setup.exe.
|
||||
|
||||
[Note: of course you can also use the Linux command line tool
|
||||
"bdisetup" to configure your BDI2000 - the sources are included on
|
||||
the floppy disk that comes with your BDI2000. Just in case you don't
|
||||
have any Windows PC's - like me :-) -- wd ]
|
||||
|
||||
Power up the BDI2000; then follow directions to assign the IP
|
||||
address and related network information. Note that U-Boot
|
||||
will be loaded to the Sandpoint via tftp. You need to either
|
||||
use the Abatron-provided tftp application or provide a tftp
|
||||
server (e.g. Linux/Solaris/*BSD) somewhere on your network.
|
||||
Once the IP address etc are assigned via the RS232 port,
|
||||
further communication with the BDI2000 will happen via the
|
||||
ethernet connection.
|
||||
|
||||
PART 4)
|
||||
Making a TCP/IP network connection to the Abatron BDI2000:
|
||||
|
||||
Telnet to the Abatron BDI2000. Assuming that all of the
|
||||
networking info was loaded via RS232 correctly, you will see
|
||||
the following (scrolling):
|
||||
|
||||
- TARGET: waiting for target Vcc
|
||||
- TARGET: waiting for target Vcc
|
||||

|
||||
Power up the target Sandpoint:
|
||||
If the BDM connections are correct, the following will now appear:
|
||||
|
||||

|
||||
Sandpoint's COM1. Set communications parameters to 8N1 / 9600 baud.
|
||||
|
||||
|

Overview
|
||||
--------
|
||||
The P4080DS is a Freescale reference board that hosts the eight-core P4080 SOC.
|
||||
|
||||
SerDes hwconfig configuration
|
||||
-----------------------------
|
||||
The P4080 RCW includes three sets of bits the specify which SerDes lanes
|
||||
should be powered down: SRDS_LPD_B1 (for bank one), SRDS_LPD_B2 (for bank two),
|
||||
and SRDS_LPD_B3 (for bank three). Each of these contains four bits, one for
|
||||
each lane in the bank. SerDes Erratum SERDES8 requires that SRDS_LPD_B2 and
|
||||
SRDS_LPD_B3 be set to 0b1111. This forces banks two and three to be powered
|
||||
down at reset.
|
||||
|
||||
To re-enable these banks in U-Boot, two hwconfig are available:
|
||||
"fsl_srds_lpd_b2" and "fsl_srds_lpd_b3". The value passed via fsl_srds_lpd_b2
|
||||
is written into SRDS_LPD_B2, and the value passed via fsl_srds_lpd_b3 is into
|
||||
SRDS_LPD_B3. Each bit represents one of each bank, and a value of '1'
|
||||
indicates that the lane should be powered down.
|
||||
|
||||
For example, to indicate that both SerDes banks 2 and 3 are powered down, add
|
||||
the following to hwconfig:
|
||||
|
||||
serdes:fsl_srds_lpd_b2=0xf,fsl_srds_lpd_b3=0xf
|
||||
|
||||
The "0xf" is a mask that corresponds to the 4 lanes A-D. The most significant
|
||||
bit corresponds to lane A. To indicate that just lane A of bank 3 is to be
|
||||
powered down, use:
|
||||
|
||||
serdes:fsl_srds_lpd_b3=8
|
||||
|
||||
These options should be specified only if U-Boot does not automatically power
|
||||
on the correct lanes.

Notes for the Qemu MIPS port
|
||||
|
||||
I) Example usage:
|
||||
|
||||
# ln -s u-boot.bin mips_bios.bin
|
||||
start it:
|
||||
qemu-system-mips -L . /dev/null -nographic
|
||||
|
||||
or
|
||||
|
||||
if you use a qemu version after commit 4224
|
||||
|
||||
create image:
|
||||
# dd of=flash bs=1k count=4k if=/dev/zero
|
||||
# dd of=flash bs=1k conv=notrunc if=u-boot.bin
|
||||
start it:
|
||||
# qemu-system-mips -M mips -pflash flash -monitor null -nographic
|
||||
|
||||
2) Download kernel + initrd
|
||||
|
||||
On ftp://ftp.denx.de/pub/contrib/Jean-Christophe_Plagniol-Villard/qemu_mips/
|
||||
you can downland
|
||||
|
||||
#config to build the kernel
|
||||
qemu_mips_defconfig
|
||||
#patch to fix mips interrupt init on 2.6.24.y kernel
|
||||
qemu_mips_kernel.patch
|
||||
initrd.gz
|
||||
vmlinux
|
||||
vmlinux.bin
|
||||
System.map
|
||||
|
||||
4) Generate uImage
|
||||
|
||||
# tools/mkimage -A mips -O linux -T kernel -C gzip -a 0x80010000 -e 0x80245650 -n "Linux 2.6.24.y" -d vmlinux.bin.gz uImage
|
||||
|
||||
5) Copy uImage to Flash
|
||||
# dd if=uImage bs=1k conv=notrunc seek=224 of=flash
|
||||
|
||||
6) Generate Ide Disk
|
||||
|
||||
# dd of=ide bs=1k cout=100k if=/dev/zero
|
||||
|
||||
# sfdisk -C 261 -d ide
|
||||
# partition table of ide
|
||||
unit: sectors
|
||||
|
||||
ide1 : start= 63, size= 32067, Id=83
|
||||
ide2 : start= 32130, size= 32130, Id=83
|
||||
ide3 : start= 64260, size= 4128705, Id=83
|
||||
ide4 : start= 0, size= 0, Id= 0
|
||||
|
||||
7) Copy to ide
|
||||
|
||||
# dd if=uImage bs=512 conv=notrunc seek=63 of=ide
|
||||
|
||||
8) Generate ext2 on part 2 on Copy uImage and initrd.gz
|
||||
|
||||
# Attached as loop device ide offset = 32130 * 512
|
||||
# losetup -o 16450560 -f ide
|
||||
# Format as ext2 ( arg2 : nb blocks)
|
||||
# mke2fs /dev/loop0 16065
|
||||
# losetup -d /dev/loop0
|
||||
# Mount and copy uImage and initrd.gz to it
|
||||
# mount -o loop,offset=16450560 -t ext2 ide /mnt
|
||||
# mkdir /mnt/boot
|
||||
# cp {initrd.gz,uImage} /mnt/boot/
|
||||
# Umount it
|
||||
# umount /mnt
|
||||
|
||||
9) Set Environment
|
||||
|
||||
setenv rd_start 0x80800000
|
||||
setenv rd_size 2663940
|
||||
setenv kernel BFC38000
|
||||

setenv addmisc 'setenv bootargs ${bootargs} console=ttyS0,${baudrate} rd_start=${rd_start} rd_size=${rd_size} ethaddr=${ethaddr}'
|
||||
setenv bootcmd 'run boot_tftp_flash'
|
||||
|
||||
10) Now you can boot from flash, ide, ide+ext2 and tfp
|
||||
|
||||
# qemu-system-mips -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
|
||||
|
||||
II) How to debug U-Boot
|
||||
|
||||
In order to debug U-Boot you need to start qemu with gdb server support (-s)
|
||||
and waiting the connection to start the CPU (-S)
|
||||
|
||||
# qemu-system-mips -S -s -M mips -pflash flash -monitor null -nographic -net nic -net user -tftp `pwd` -hda ide
|
||||
|
||||
in an other console you start gdb
|
||||
|
||||
1) Debugging of U-Boot Before Relocation
|
||||
|
||||
Before relocation, the addresses in the ELF file can be used without any problems
|
||||
by connecting to the gdb server localhost:1234
|
||||
|
||||

2) Debugging of U-Boot After Relocation
|
||||
|
||||
For debugging U-Boot after relocation we need to know the address to which
|
||||
U-Boot relocates itself to 0x87fa0000 by default.
|
||||
And replace the symbol table to this offset.
|
||||
|
||||
