GUI 5.3 Added debug functions shown in Figure 6-21.

Click the Debug Tab button at the side of the Peripherals Panel to display Figure 6-21.

Figure 6-21 Debug Tab

Selecting the Enable Debug mode checkbox enables the debug functions shown in on the Debug Tab.

• The Destination ASIC does not apply to single controller systems and the options remain grayed out.
• The Controller Memory Read/Write box allows Reading from and Writing to memory address on the controller.

  The From box is grayed out for single controller systems since there is only the default (primary) controller.

  CAUTION: Read from or write only to defined addresses. Reading from or writing to undefined addresses results in unpredictable behavior!

  There are two virtual interfaces to assist in debugging. For example Reading from or Writing to some addresses can result in changes in other memory locations. The result of writing to a memory using Interface 1 can be tracked in Interface 2.

  The Secondary - Read Data box is grayed out for single controller systems.

  The following are valid memory address ranges:

  • 0x00000000 - 0x00003FFF
  • 0x11000000 - 0x11003FFF
  • 0x11005000 - 0x1100AFFF
  • 0x1100F000 - 0x110137FF
  • 0x11014000 - 0x110177FF
  • 0x11018000 - 0x110187FF
  • 0x11019000 - 0x110197FF
  • 0x11020000 - 0x11023A40
  • 0x11024000 - 0x11025FFF
  • 0x20000000 - 0x27FFFFFF
  • 0xA7000000 - 0xA7FFFFFF
  • 0xF7FEC000 - 0xFAFFFFFF
  • 0xFFFF0000 - 0xFFFFFFFF

• The Debugging Trace box allows the user to enable various debug areas to report detailed debug information to the DLPC900 UART beyond the always printed debug messages output during regular operation. Select the Enable debug message checkbox to allow the following individual masks to be enabled or disabled separately:

  Dubug Masks - detailed descriptions:

  • System information - Enable printing of debug messages regarding system functions like system initialization, memory allocation, batch command execution.
  • Datapath information - Enable printing of debug messages regarding datapath like datapath initialization to process video input, ITE, HDMI, DP information, and System state transition.
  • Projector Control Information - Enable printing of debug messages regarding projector control like initialization of USB and I2C command port, command message handler, and command processing.
  • I²C handler - Enable printing of debug messages regarding I2C communication interface.
  • UART handler - Enable printing of debug messages regarding UART communication interface.
  • USB handler - Enable printing of debug messages regarding USB communication interface.
  • Always Printed (on by default) - Enable printing of debug messages regarding system, power-up, illumination, memory initialization, state transitions, application layer command processing.
  • Mailbox message - Enable printing of debug messages regarding application mailbox interface.
  • Environment information - Not used
  • PTN Information - Enable printing of Pattern Info debug messages regarding loading of splash images to FMT memory or loading a BMP pattern.
  • PTN debug - Enable printing of Pattern Info debug messages regarding sequence database, selected sequence information, encode and decode of sequences, pattern parameter setup, etc.
  When debug messages are enabled, pressing Get retrieves the currently enabled masks. After selecting the desired masks pressing Set enables the selected masks. The Debug Mask text box shows, in hex, the overall mask value. The value can be used in the Firmware Power up Defaults section to build a firmware with the desired masks enabled at power up.
  Note: Deselecting Enable debug message disables all debug output except Always Printed items

  Max String Length - reads the maximum allocated string size for the debug message

  Currently Used - reads the string size currently used by the debug message

• The Memory Access Batch Files box enables special batch files that can be provided by TI during advanced debugging.

  Select the Record result check box to record the result of running a provided batch file. Results are recorded in the same directory that the batch file resides.

  Use Open memory access batch File button to navigate to a memory access batch file provided.

  Use Run memory access batch file button to run the batch file selected by the Open memory access batch File.

• Diagnostic Window Settings

  Select the Enable or Disable button to show or hide diagnostic log windows. Enablilng this option shows a command log window under the main GUI window are as shown in Figure 6-22.

  Figure 6-22 Diagnostic Window

  These logs are available:

  • Select the Enable Projector Control Log tab. Records every command sent to the DLPC900 and the status of transaction. Records the system initialization and status commands the first time the DLPC900 is powered up.
  • Select the Enable Command Log tab. Records information such as command name, command ID, sent and received message packet, status of transaction.
  • Select the Enable Periodic Status Log to show the periodic status polling commands in the Projector Control tab. Records the DLPC900 main, HW, system status query commands sent by the GUI. This occurs at 120 second intervals. Enabling this records these commands each time the commands are sent. This causes slow response from the GUI.

  For the Projector Control log and Command log the following options are available:

  • Select all - selects all of the contents of the selected log tab to be copied.
  • Copy - copies to the clipboard the currently selected items in the selected log tab. Drag click to select a subset of the log to copy.
  • Clear all - clears all of the current entries in the selected log tab.
  • Save to File - saves the current selected log tab entries to a file.
