DLP lightcrafter 3000 does not boot after inserting SD card

Parmiss Mojir Shaibani

Hi,

The following led to the DLP lightcrafter 3000 shutting down after the boot menu completes:

I downloaded the latest software bundle 3.0 from the website. I then tried to upgrade the DM365 through an SD card. I had previously used this SD card for upgrades and had no problems. This time, once the DLP completed booting through the SD card, the LED flashed green and everything was ok. Then I switched the switch away from the SD card (back to ON) and when I connected the power, the DLP turned off after the booting screen completed (no colored bars).

After the DLP shuts down, a blinking red LED near the power connection (on the lower board) started flashing. The red LED stays on for about 5 or 6 seconds, turns off for under a second and then flashes. I don't know if there is any relation between the attempt to upgrade and this problem. Can you please help me figure out how to overcome this issue? Is the power a possible source of the problem?

Thanks,

Parmiss

    Hello Parmiss,

    Could you create another SD card with SD boot image (file name dm3xx_sd.dat) with previous build v4.0. Now put the LightCrafter switch to boot from SD mode. Power ON the kit let me know if you are able to get the boot sequence complete.

    Hello Parmiss,

    Look at the following step by step instructions on how to upgrade the DM365 fimrware :

    Steps to follow to boot it up from SD card:

    •             Format the SD Card (The SD card I used is Transcend 4GB micro SD HC).

    •             Run this command on the Command prompt (opened with administrator permissions)

    •        Navigate to the directory “SD Card Utility” inside the downloaded 3.0 Bundle that has .dat file

    o             lcr_boot_sd.exe dm3xx_sd.dat  F:  (or whatever SD card drive is mounted) 

    •             Make sure it comes back and says , Image successfully copied.

    •             Remove the SD card and put it inside the SD card slot on lightcrafter, flip the switch towards the SD card and power it up

    •             You should see a series of images/ splash screens like the one attached

    •             You should not need to flip the switch to the other side in this process.

    •             Note that now onwards, you will always need the SD card inserted in LighTcrafter and the switch always towards the SD card.

    •             Eventually the LightCrafter should boot up completely and you should see the RGB bars and the LED D1 should be blinking Red and green continuously.

    •        After this step, you should be able to connect to it from the GUI (download the latest form LightCrafter 3.0 Software and Firmware Bundle)

     

     

    Steps to follow to boot it up from NAND:

    •             Format the SD card

    •             Run the command  lcr_boot_sd.exe dm3xx_NAND.dat  F:  (or whatever SD card drive is mounted)

    •             Now insert the SD card into the SD card slot, make sure the switch is towards the SD card

    •             Power up the Lightcrafter, again watch series of the splash images and watch the LED D1.

    •             As soon as the LED D1 turns green, then flip the switch away from SD card and power the Lightcrafter down and power it back.

    •             Now what it means is, it has copied the firmware over to NAND flash part on the board. Now you can even remove the SD card and it should boot up from NAND.

    •             Note that, now onwards the switch always needs to be in a position away from SD card.

    If you follow these steps, it should be pretty straight forward to upgrade the firmware and boot up the LightCrafter.

    Let me know if you still have any issues.

    Regards

    Hi Sanjeev,

    Thanks for your response. I did as you said and I could successfully boot up with the previous build; however, the same thing happens again when I try to upgrade to the newer version. The problem is, now even with the new SD card, I can't get the older version to work either! Doesn't boot up anymore. Do you think my new SD card is also ruined?

    Hi Manasi,

    Thanks for answering but Sanjeev's approached worked. Unfortunately I still have a problem with the new upgrade and now I can't even use the older version to boot up the system.

    Hello Parmiss,

    We have already put the Technical Advisory about the SD card here looks like the problem  could be with SD card damaged or not supported. 

    See 1.3 in this http://www.ti.com/lit/er/dlpt003/dlpt003.pdf

    Sorry, but even a new SD card in compliance with your standards (Kingston 4GB) no longer helps me boot the system. It just turns off and now I cannot do any of my experiments. It's as if it doesn't even try to read from the SD card anymore. I don't know what the problem is, but it all started when the new upgrade was introduced.

    Hello Parmiss,

    As you know there are two boot dat files one that program the NAND flash and other that boot from SD card directly. You can use the SD for debugging the file name is dm3xx_sd.dat. 

    Please send us the UART log dump when you try either. It will he helpful for us to figure out what is going wrong.

    Hi Sanjeev,

    Thank you for replying. I have never used the NAND file, always the other file. So is there any other file that has the UART log stored or is it just the dm3xx_sd.dat that is modified? Please walk me through getting the UART log dump so I can send you the right information.

    Thanks,

    Parmiss

    Hello Parmiss,

    The DM365 f/w has two flavors dm3xx_nand.data and dm3xx_sd.dat. 

    dm3xx_nand.data - when you use the file in the SD card, it will basically program the NAND flash. So if you remove the SD card and put the switch to boot from NAND flash, it will now boot from NAND flash with firmware you upgraded.

    dm3xx_sd.dat - it will not program or update the NAND flash, it will basically boot from SD card so this flavor not touches the DM365 firmware already stored in NAND flash.

    UART log is the something output from the DM365 f/w via UART port as debug print statements more about UART is discussed here http://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/f/850/t/253060.aspx
