New Firmwares on "old" LightCrafter

Erik Klaas

Hi everybody,

I wonder whether I can try to install all the latest firware versions (4.0 for DM365, 2.6.43 for FPGA, 2.6 for MSP430) on my old lightcrafter that is about one year old and still hardware version 1.0.

Is there any risk or will I not be able to use all new features?

    Hi Erik,

    The LightCrafter hardware version 2.0 will have the R205 installed for Extended Pattern Sequence mode to establish a GPIO connection with the NAND flash to send patterns.

    Other than that, I believe the rest of the features should work as expected.

    Regards,

    Thanks Divya,

    I updated the software to the following versions on my LightCrafter 1.0 hardware:

    DM365: 4.0

    FPGA: 2.6.43

    MSP430: 2.6

    It boots normaly and I can also connect throught USB as expected and also see the test images.

    But I have an issue with the pattern sequence mode: when I try to go to the pattern sequence mode it looses the USB connection and I have to go throught a power cycle to make it wotk again. Any ideas what else I can try?

    Unfornuately going back to an older DM365 (3.0) doensn´t help either, it still shows this behavious of loosing the USB connection.

    Hi Erik,

    This behavior is strange. When the display mode is set to pattern sequence, do you see the LED D1 blinking on the systems board?

    what is the status of D3 on driver board? I am trying to understand if the board is still operating as expected in this mode.

    Dear Divya,

    after reading through some of the other threads I decided to start over and reformatted the SD Card, put the firmware on it and reinstalled the DM365 4.0 version. This seems to have solved the problem. Everything works! Thank you!

    But one more question regarding differences betwenn 1.0 and 2.0 hardware. Is it correct that the maximum exposure time in pattern sequence mode is something like 20000 µs adn much longer in the 2.0 Hardware? What are the exact maximum times?

    Best regards

    Erik

    Dear Erik,

    Its good to know that re-flashing the NAND fixed the booting problem.

    In extended pattern sequence mode, you can set an exposure period of 2 secs for 1-bit patterns and up to 5 secs for 8-bit patterns.

    To enable this mode on LightCrafter bard with 1.0 hardware, you have to install R205 on the system board to establish a GPIO connection with NAND flash to send patterns.

    The limitation in this mode is that when more than 96 patterns are uploaded in "Pattern Sequence Mode", the minimum trigger period is 18ms.

    More details are explained by Sanjeev in this E2E post.

    Regards,

    Divya

    Thanks Divya,

    so I will install R205 and test it. Just one last question: In some other post I read that I also do have to remove R202.

    Is that still the case?

    Erik,

    I believe R202 is not populated by default. But, please double check on your board.

    Divya,

    I installed R205 and R202 was installed too on my board. I left it installed and everything is working now as expected, which I am very happy about ;-)

    Just out of curiosity, what is R202 good for? What would change if i remove it?

    Erik,

    R205 connects a signal from the FPGA to a DM365 interrupt. 

    R202 connects a signal from the MSP430 to a DM365 interrupt.

    The MSP430 signal is not used in the current software version. 

    Best regards,
