Supports emulated flash (patch Jean-Christophe PLAGNIOL-VILLARD) with
recent qemu versions. When using emulated flash, launch with
-pflash <filename> and erase mips_bios.bin.
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 kernel BFC38000
setenv oad_addr 80500000
setenv load_addr2 80F00000

setenv load_addr_hello 80200000
setenv bootargs 'root=/dev/ram0 init=/bin/sh'
setenv load_rd_ext2 'ide res; ext2load ide 0:2 ${rd_start} /boot/initrd.gz'
setenv load_rd_tftp 'tftp ${rd_start} /initrd.gz'
setenv load_kernel_hda 'ide res; diskboot ${load_addr} 0:2'
setenv load_kernel_ext2 'ide res; ext2load ide 0:2 ${load_addr} /boot/uImage'
setenv load_kernel_tftp 'tftp ${load_addr} /qemu_mips/uImage'
setenv boot_ext2_ext2 'run load_rd_ext2; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
setenv boot_ext2_flash 'run load_rd_ext2; run addmisc; bootm ${kernel_flash}'
setenv boot_ext2_hda 'run load_rd_ext2; run load_kernel_hda; run addmisc; bootm ${load_addr}'
setenv boot_ext2_tftp 'run load_rd_ext2; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
setenv boot_tftp_hda 'run load_rd_tftp; run load_kernel_hda; run addmisc; bootm ${load_addr}'
setenv boot_tftp_ext2 'run load_rd_tftp; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
setenv boot_tftp_flash 'run load_rd_tftp; run addmisc; bootm ${kernel_flash}'
setenv boot_tftp_tftp 'run load_rd_tftp; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
setenv load_hello_tftp 'tftp ${load_addr_hello} /examples/hello_world.bin'
setenv go_tftp 'run load_hello_tftp; go ${load_addr_hello}'
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

PART 2)
Connect the BDI2000 Cable to the Sandpoint/Unity 8240:
BDM Pin 1 on the Unity 8240 processor board is towards the
PCI PMC connectors, or away from the socketed SDRAM, i.e.:

====================
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
PART 5)
Power up the target Sandpoint:
If the BDM connections are correct, the following will now appear:
- TARGET: waiting for target Vcc
- TARGET: waiting for target Vcc
- TARGET: processing power-up delay
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed

This document contains different information about the port
of U-Boot for the OXC board designed by Lucent Technologies,
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):
- TARGET: waiting for target Vcc
- TARGET: waiting for target Vcc
PART 5)
Power up the target Sandpoint:
If the BDM connections are correct, the following will now appear:
- TARGET: waiting for target Vcc
- TARGET: waiting for target Vcc
- TARGET: processing power-up delay
- TARGET: processing user reset request
- BDI asserts HRESET
- Reset JTAG controller passed
- Bypass check: 0x55 => 0xAA
- Bypass check: 0x55 => 0xAA
- JTAG exists check passed
- Target PVR is 0x00810101
- COP status is 0x01
- Check running state passed
- BDI scans COP freeze command
- BDI removes HRESET
- COP status is 0x05
- Check stopped state passed
- Check LSRL length passed
- BDI sets breakpoint at 0xFFF00100
- BDI resumes program execution
- Waiting for target stop passed
- TARGET: Target PVR is 0x00810101
- TARGET: reseting target passed
- TARGET: processing target startup ....
- TARGET: processing target startup passed

PART 8)
Connect PC to Sandpoint:
Using a crossover serial cable, attach the PC serial port to the
Sandpoint's COM1. Set communications parameters to 8N1 / 9600 baud.
PART 9)
Reset the Unity and begin U-Boot execution:
BDI>reset
- TARGET: processing user reset request
- TARGET: Target PVR is 0x00810101
- TARGET: reseting target passed
- TARGET: processing target init list ....

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 oad_addr 80500000
setenv load_addr2 80F00000
setenv kernel_flash BFC38000
setenv load_addr_hello 80200000
setenv bootargs 'root=/dev/ram0 init=/bin/sh'
setenv load_rd_ext2 'ide res; ext2load ide 0:2 ${rd_start} /boot/initrd.gz'
setenv load_rd_tftp 'tftp ${rd_start} /initrd.gz'
setenv load_kernel_hda 'ide res; diskboot ${load_addr} 0:2'
setenv load_kernel_ext2 'ide res; ext2load ide 0:2 ${load_addr} /boot/uImage'
setenv load_kernel_tftp 'tftp ${load_addr} /qemu_mips/uImage'
setenv boot_ext2_ext2 'run load_rd_ext2; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
setenv boot_ext2_flash 'run load_rd_ext2; run addmisc; bootm ${kernel_flash}'
setenv boot_ext2_hda 'run load_rd_ext2; run load_kernel_hda; run addmisc; bootm ${load_addr}'
setenv boot_ext2_tftp 'run load_rd_ext2; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
setenv boot_tftp_hda 'run load_rd_tftp; run load_kernel_hda; run addmisc; bootm ${load_addr}'
setenv boot_tftp_ext2 'run load_rd_tftp; run load_kernel_ext2; run addmisc; bootm ${load_addr}'
setenv boot_tftp_flash 'run load_rd_tftp; run addmisc; bootm ${kernel_flash}'
setenv boot_tftp_tftp 'run load_rd_tftp; run load_kernel_tftp; run addmisc; bootm ${load_addr}'
setenv load_hello_tftp 'tftp ${load_addr_hello} /examples/hello_world.bin'
setenv go_tftp 'run load_hello_tftp; go ${load_addr_hello}'
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
