Install LightcrafterGUI on Pandaboard

Hi,

I've just received a lightcrafter module which will be connected to a Pandaboard for further study. This Pandaboard (armv7) is running ubuntu 11.10 and using Xfce as the graphical desktop.

I downloaded the latest DLP LightCrafter Firmware and Software Bundle for Linux (DLPLCr_FW_SW_v2.0_LNX_05_06_2013).

Before running the GUI installation, libqtgui4 was installed. Then, I followed the instruction to install the DLP LightCrafter GUI v4.0. After I ran ./LightcrafterGUI 

I got an error:

bash ./LightcrafterGUI: cannot execute binary file

Form the Readme file, I understand the LightcrafterGUI is using libqtgui4:i386. Therefore, I think the error is caused by running an executable file on a different architecture (x86 vs ARM).  Is it possible for TI to provide a LightCrafterGUI version which can support ARM architecture?

Thank you very much.

Can

    Hi Can Can,

    Welcome to TI E2E Community!

    Unfortunately the LightCrafter GUI is supported only in x86 and x64 (with libQTgui4:i386 library). We haven't seen any demand in the past for ARM compatibility, and might consider providing this version in near future (4-6 months).

    Hi Divya,

    Thank you very much for your reply.

    Initially, I thought the the DLP development platform had been supporting ARM architecture since the DLP Pico Projector Development Kit was developed on Beagleboard. My Lightcrafter project aims to use Pandaboard as a system control, therefore, I look forward to seeing the ARM compatible Lightcrafter GUI  from TI.

    Meanwhile, I upgraded the latest firmware and FPAG of Lightcrafter through Windows PC. Then, I compile the simple API code on Pandaboard and I have no problem to connect to the Lightccrafter.

    Results of running Demo #1:

    DM365 Revision: 3.31

    FPGA Revision: 2.4.39

    MSP430 Revision: 2.5

    There are 9 domes in the API package. However, I can only run Demo#1, #2 and #3. When I try to run Demo#4 to #9, I get an error:

    INFO: Command packet has ERROR in it

    COMMAND PACKET ERROR: Command Failed.

    I look at the API code, the error seems to come from any demo related to download Pattern Sequence. Am I wrong?

    Could you help me to solve this error?

    Thank you very much.

    Hi Can,

    I apologize for the delay. The API Sample Code v1.0 was developed for DM365 v2.5. Th DM365 v3.31 has added features like Internally Generated Pattern Mode and Extended Pattern Sequence Mode. Due to addition of extra byte in the DM365 code, the demos 4 through 9 does not work in API Sample Codev1.0.

    The new version of API Sample code (v2.0) and DM365 (V4.0) are available as a part of DLP LightCrafter Firmware and Software Bundle v2.0. Scroll down to "Available Versions" section. The Sample code is developed to support both Windows and Linux users. Click on appropriate OS link.

    Regards,
