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
|
||||||
|
|
||||||

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):
|
||||||
|
|
||||||
|

PART 5)
|
||||||
|
Power up the target Sandpoint:
|
||||||
|
If the BDM connections are correct, the following will now appear:

This document contains different information about the port

Inc.

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):
|
|
||||||
|
|

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

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

|
|
||||||
|
|
||||||
5) Copy uImage to Flash
|
|
||||||
# dd if=uImage bs=1k conv=notrunc seek=224 of=flash
|
|
||||||
|

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

|

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
|
|
||||||
|
|
||||||
# mipsel-unknown-linux-gnu-gdb u-boot

||||||

|
|
||||||
|
|
||||||
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.
|
|
||||||
|
|
||||||
(gdb) symbol-file
|
|
||||||
Discard symbol table from `/private/u-boot-arm/u-boot'? (y or n) y
|
