2.6. JTAG Programming
The GW2342 Flash memory is programmed through the JTAG port. Gateworks
offers a low cost GW16102 JTAG programmer that enables the developer to
program or recover the Flash image through a standard PC parallel port.
Gateworks also offers a GW16013 JTAG gang programmer for simultaneously
programming up to 16 GW2342 processors in a production environment.
The following are the steps required to use the GW16012 JTAG programmer.
1. Connect the GW 16012 JTAG programmer to a PC parallel port using the
standard DB25 cable included with programmer.
2. Connect the 10-pin IDC female from the GW16012 dongle to the GW2342
JTAG connector.
3. Create a bootable DOS floppy with the FLASH.EXE program and the
binary image. The FLASH.EXE program is a DOS program, which must
be run from a DOS prompt, it cannot be run from a Windows DOS box.
The development kit CDROM contains both the FLASH.EXE program and
the default factory programmed image.
4. Insert the DOS bootable floppy, with the FLASH.EXE program and binary
image into the PC’s floppy drive and boot to DOS.
5. Run the FLASH.EXE program with the following syntax
CC:> flash
image.bin
{p} {v} where p=program, v=verify and
image.bin
is
the binary image.
Examples:
C:> flash gw2342.bin p
Program the Flash with the gw2342.bin image
C:> flash gw2342.bin v
Verify that the Flash matches the gw2342.bin image
C:> flash gw2342.bin pv
Program and verify the Flash with the gw2342.bin image
