Introduction
The TSB42AA9 (StorageLynx) EVM is a free-standing evaluation module
that acts as a bridge between a PC or Macintosh 1394 bus and an ATA/ATAPI
device. It is used to evaluate system compatibility, to develop optional soft-
ware that resides in external memory for StorageLynx, and to develop device
drivers. It also provides a TSB42AA9 hardware reference design for connec-
tion to an ATA/ATAPI device such as a hard disk drive (HDD), ZIP drive, Mag-
neto-Optical drive (MO), ORB, CD-ROM, CD-R/W, DVD-ROM, and DVD-
RAM.

3.2 StorageLynx EVM Hardware Installation
The following parts/devices are needed to set up the EVM:
1394 cable
ATA/ATAPI device (HDD, etc.)
ATA/66 ribbon cable
PC power supply for ATA/ATAPI device
PC/Macintosh with 1394 connection (PC with Windows 98SE is
necessary for the programming application)
To set up the EVM, perform the following steps:
1) Ensure the ATA/ATAPI device power supply is off.
2) Connect the ribbon cable between the EVM board and the ATA/ATAPI
device.
3) Connect the ATA/ATAPI device to the power supply.
4) Configure the StorageLynx EVM switch settings as shown in Figure 3–3.
Mode 1 will be used for most development applications.
5) Turn on the ATA/ATAPI device power supply.
6) Connect the 1394 cable between the EVM and the PC/Macintosh. The
PC/Macintosh can be running.

StorageLynx EVM Programming Application Overview
4-2
4.1 StorageLynx EVM Programming Application Overview
The StorageLynx EVM bundle contains the following software files:
S2LynxVC.exe. StorageLynx programming application executable file.
Support files:
SEQFWAPI.reg. Registration file for registry edits.
SEQFWAPI.sys.
WAPI1394.dll.
Sbp2lynx.hex. Flash memory software. Intel Hex file format output by
most 8051 compilers.
TI_HDD.eep. Config ROM file for HDD, ZIP, MO, and ORB devices.
TI_CD.eep. Config ROM file for CD–ROM, CD–R/W, DVD–ROM, and
DVD–RAM devices.
The EVM programming application software is used to download code to the
flash memory or the EEPROM on the EVM to allow normal or developmental
use of the ATA/ATAPI device attached to the EVM. The S2LynxVC program
can load a configuration ROM file into the serial EEPROM or program code
(firmware) into flash memory. When the software is loaded, a message ap-
pears on the computer screen that Flash or EEPROM reprogramming has
been completed. The ATA/ATAPI device connected to the EVM is then avail-
able for normal use or, in the case of custom software, the ATA/ATAPI device
can be tested to ensure proper operation.
Custom software may be loaded to the flash or EEPROM using S2LynxVC.
Example firmware code, with licensing restrictions, is available from Texas
Instruments for use in custom software development. The following general
guidelines should be followed for developing custom .eep files:
Configuration ROM files must be in the same format as the included
Config ROM file (TI_HDD.eep).
Comments are allowed, but must be preceded by //.
The first line in the file must be a header, because the application
calculates cyclic redundancy checks (CRCs) and places them in the
proper locations. CRC values are all F in the .eep files.
The first number in the header is the number of blocks after the
BUS_INFO_BLOCK (in TI_HDD.eep this is ROOT DIRECTORY, UNIT
DIRECTORY,AND3TEXT LEAVES). The next 5 numbersaretheoffsets
of each block from 0x400.

Note:
Included software will run only under Windows 98SE.
There is currently no automatic install utility included with the EVM. To install
the software on the PC, perform the following:
Copy WAPI1394.dll to c:\windows\system.
Copy SEQFWAPI.sys to c:\windows\system32\drivers.
Create a folder for all other EVM files and copy the rest of the files to that
folder.
Execute SEQFWAPI.reg by double clicking on the file.
Reboot the PC.
