choose the "csb337", and in the "Select an Image to build:" column
choose "bootrom.hex" and press the "OK" button.
2.3 After the build process will finish successfully (You will see "Done" in
the "Build window" without error), you will have the bootrom_uncmp.hex in
your BSP directory "$(WIND_BASE)/target/config/csb337".
3. Programming bootrom to CSB337 NOR FLASH:
If you are using visionCLICK please follow the instruction in section 3.1
The emulator files are provided in a separate package.
3.1 Using visionCLICK:
3.1.1 Install the visionPROBE II or visionICE II and power it on.
Connect the JTAG interface cable from the visionPROBE II or
visionICE II into the CSB337 board JTAG connector.
Once all the connections have been made, power up the CP2
board and start the visionCLICK executable on the host.

visionCLICK installation. After choosing the register file press
on the "Open" button to confirm the selected reg file. You will
return back to the "Record / Playback" dialog box. Now press on
the "Start" button located in the same group. In the "Terminal"
window you can see that the visionCLICK is running the script.
When visionCLICK will finish the playback you will get back the
">BKM>" or the ">ERR>".
3.1.4 Get into Background Mode:
Execute the "IN" command to reset the board and initialize it with
the register setting.
IN
This command is the reset command to initialize the board.
3.1.6 Converting the bootrom:uncmp.hex to bootrom_uncmp.bin:
3.1.6.1 In visionCLICK, choose "Convert Object Modules" from the
"Tools" menu. The "CONVERT BINARY AND SYMBOL OBJs" dialog
box will pop up.Select "All Files" in the "Files of Type"
box. Go to the "Select Input Object Module To Convert"

this window using the "visionICE Utilities Panel" and follow the
steps below:
3.1.7.1 Click the "Select" in the "Flash Card or PC Host File
Name and Path" group. The "CHOOSE A FILE FROM HOST PC"
dialog box will popup. In the edit box enter the full path
to the location of the "bootrom_uncmp.bin", or use the
"<--Browse" button to browse to the file location. Go to
the "+/- Bias" group and enter the number "0" in
the edit box. Now click the "OK" button, this will bring
you back to the "TF FLASH PROGRAMMING" dialog box.
3.1.7.2 In the "Programming Algorithm" group in, the edit box
press on the "Select" button, and select one of the
following Flash devices:
For the 8MB Flash: "INTEL 28F640Jx ( 4096 x 16 ) 1 Device "
3.1.7.3 Set the proper address of the Flash to "10000000", check
the "Erase All" radio button,and set the
"Available RAM Workspace" setting to "00200000", set the
"Bytes Of Target RAM Required" to "00200000".
3.1.7.4 Press the "Erase and Program" button.
3.1.7.5 Now the Flash memory is programmed with the new boot
program.
3.2 Using Flash tool programmer in a vxWorks image
3.2.2 Build a new bootrom_uncmp.bin image with the project tool for CSB337 BSP with
the Menu Build->Build BOOT Rom and copy the bootrom_uncmp.bin file in the same directory
as the vxWorks image downloaded by FTP.
3.2.3 Boot the rebuilt vxWorks image and type the following command on the shell :
->sysFlashUpdateFromFile "host:bootrom_uncmp.bin",0
4. Running the VxWorks Boot ROM program:
4.1 Disconnect visionPROBE II or the visonICE II if it still connected to the
board, because it still connected to the board in some case it can stop
the processor at the first instruction.
4.2 Connecting the Ethernet channel and the serial channel:
4.2.1 First, connect the supplied serial cable with the board. On
one said connect the SUB-D9 connector to the RS232 port on the "Serial 1"
of the CSB337 board, and on the other connect it to your host. The UART
devices is set as follow: 8 data bits, 1 stop bit, hardware
handshaking, and parity disabled. The serial console (38400 bps).
4.2.2 Second, connect a standard Ethernet cable to the the RJ45
connector on the CSB337 board.
4.3 Launch a terminal program on the host side, and configure it according
to the following details: 8 data bits, 1 stop bit, no parity no hardware handshaking.
The serial console baudrate is 38400 bps.
4.4 Now to execute this new boot program turn the board off,and on. and you
should get the vxWorks boot count down on the terminal window. Press any
key to stop the count down. Now follow the instruction in the
instructions in the "Getting Started" chapter of the
"VxWorks Programmer's Guide." for more detail how to configure vxWorks.
.CE
.SH "SPECIAL CONSIDERATIONS"
This section describes miscellaneous information that the user needs
to know about the BSP.
.SS "ARM Thumb mode"
The ARM Thumb mode is not supported in this BSP.
.SS "Delivered Objects"
No pre-compiled objects are delivered with the BSP.
.SS "Make Targets"
The make targets are listed as the names of object-format files. Append `.hex'
to each to derive a hex-format file name. Append `.bin'
to each to derive a bin-format file name.
In order to program the flash using VisionClick, please use the bootrom hex files.
'vxWorks', 'bootrom', 'bootrom_uncmp', 'vxWorks_rom' have been succesfully
generated and tested with GNU compiler.
.SS "Special Routines"
The following routines are specific to this BSP and are available
to the user. The are written in C code in sysLib.c. For
further details see the man pages:
.TS
expand;
sysPeripheralIntConnect() | connect a routine to a system peripheral interrupt
sysPeripheralIntEnable() | enable system peripheral interrupts
sysPeripheralIntDisable() | disable system peripheral interrupts
sysLedSet() | set a user LED value
.TE
NOTE: The first three routines are reserved for managing the interrupt level 1 (system peripheral interrupts).
.SS "SRAM usage"
The first 0x120 Bytes are reserved for VxWorks for the vector table,
FIQ code (not supported in this BSP) and the Exception Pointers.
The END Driver for the EMAC interface use the SRAM at offset 0x200 for the receive
buffer descriptor (8 bytes per descriptor).
The amount of memory used is depending on the number of descriptors defined for
the driver (see initialisation string in sysEnd.c).
.SS "Divide by Zero Exception"
The ARM architecture does not provide for an integer divide by zero
exception. Consequently, no exception is generated when an integer
divide by zero operation is performed programmatically and may provide an unpredictable result.
.SS "Target server options"
When the BSP is configured for using the serial interface as WDB connection.
It is necessary for the target server to increase the backend timeout and backend retry counts
(the "-Bt" and "-Br" options) from their defaults. For example, -Bt 20
-Br 5 when using PPP at 38400 baud.
.SS "Known Problems"
BSP Validation Test Suite (VTS)
For the test the serial lines shall be configured to 38400.
An host computer with real COM port is required. Test on Host with emulated port
(i.e. laptop or USB to serial adapter) may fail.
error1:
Divide by zero is failing (see "Divide by Zero Exception).
This a known behavior on ARM architecture.
timestamp:
As the timestamp is based on the system clock, it cannot be disabled.
This is why the test "disable the timestamp timer" is skipped.
unsupported tests: scsi, busTas (specific VME Bus), procNumGet (not implemented).
The CSB337 BSP pass all other tests
.SS "Other"
.IP "Instruction/Data Cache Mode"
When MMU is enabled, instruction cache has to be set to CACHE_WRITETHROUGH and
data cache to CACHE_COPYBACK (only supported for ARM920T).
For more details refer to the architecture suplement documentation.
