3.10 JTAG Flash Programming
The DLPC900 JTAG Programmer Tool is included in the DLPC900REFSW bundle. It allows a user to
program the bootloader image into the flash using the JTAG boundary scan connector if, for example, the
bootloader becomes corrupted and the board is rendered inoperable. The tool can also be used for
updating the entire firmware image. Programming the entire firmware image using this method may take a
long time. It is suggested to program only the bootloader using this method, and then use the DLP
LightCrafter 6500 & 9000 GUI with a USB connection to upload the entire firmware image. The following
steps will be for programming only the bootloader image.
The DLPC900 JTAG Programmer Tool requires the UM232H module with modifications. The UM232H
module can be purchased from Digi-key with the following part number: 768-1103-ND. The driver can be
downloaded from the FTDI website. Select the VCP CDM WHQL Certified driver for Windows.
Make the following modifications to the UM232H and use
and
as a guide.
