DLPLCR90EVM: DLPLCR90EVM Issue

Hello Jejomar,

Please have the customer take a screenshot of the main GUI page during operation of this particular DLPLCRC900DEVM board with the particular DLPLCR90EVM attached.

Please post it here.

Also please clarify, do they have one controller EVM and three DMD EVMs or do they have three controller EVMs and three DMD EVMs?

Hello Fizix,

Below are images that shows the different board design from the standard one. Attached DLP1 image is the old one the customer has and the DLP2 image is the new one purchased recently.

DLP1:

DLP2:

It seems they are the same model, yet the old one looks more like the board design of the screenshot image.

Here are also the some screenshots and video recording regarding the errors that the customer has encountered.

Please let me know if you need further information.

Hello Fizix,

Just to add, the customer has three sets of DLP board combination - two old sets and one new set. So, they are "three controller EVMs and three DMD EVMs".

Hello Jejomar,

I would suggest the customer to reprogram the complete flash image, including the bootloader. See Section 4.9 in DLPC900 dual EVM user guide.

Let us know if this works. If not, please share a screen capture of the status flag in the GUI.

Thank you,

Hello Aishwarya,

Customer attempted to follow the procedures from the User Guide section 4.9 and 4.12 but unfortunately, nothing seems to work. Below is his feedback:

"I have checked flash memory is empty, and LUT never worked as before. Also, JTAG flash programmer does not open. I attached the error image below.

It is not in English but it's kind of saying that the application program side-by-side composition is wrong, therefore the program can't be initiated. Please refer to the application program event log or use sxstace.exe tool on the command.

Also, can I use the black jumper cap on the J11 as a boot-hold jumper? it seems like the cap does not fit. Hope we'll get this problem fixed as soon as possible.

Lastly, there's nothing on the status checkbox that's also shown in the video I had recently attached."

Kind Regards,

Jejomar

Hello Jejomar,

For now you can simply use a lead with clips to short the pins of J11 together or a clip that will span the two pins.

I notice that the FW on the board you have is 6.0.0, but you are using GUI 5.3.0.  Do you still have GUI 5.0.0.  If so please try programming FW 6.3.0 from GUI 5.0.0.  I suspect the Flash Parameters file is does not have the correct entry the flash on the EVM you are trying to program.

Regarding the "side-by-side" error, that is a windows issue.  I do not know if Aishwarya has a solution to that or not.

Hello Fizix,

Thanks for the update. The customer tried programming FW 6.3 from GUI 5.0 but still encountered an issue.

Hello Fizix,

Here are some latest updates from the customer:

1. Here I have another error message as shown in the screenshot attached. It says "Bootloader needs an update. Existing on HW- v0.0.0. New - 3.0.0." When I yes to update it. It has come full circle and shows the "unable to read the flash device ID" again.

2. I installed a jumper on J11 and followed the instructions for the bootloader, but it didn't work.

3. Our lab turns out to have other two pairs of DLPLCRC67DEVM sets. I tried them with DLPLCRC900DEVM, but it still did not work.

4. We have spare flex cables, so I switched them, yet it didn't work.

5. I reprogrammed the flash image again, but the results are the same.

6. I have changed the positions of some jumpers, please refer to the screenshot and let me know if jumper relocation is necessary.

7. Including the screenshot of the error message, here's also an image of another DLPCR90EVM in our lab that is working fine. It appears to be showing some random pattern on the display as soon as the power is on, and I have never seen them on the new sets with problems.

After trying a total of 5 sets of DLP ( 2 sets of old DLP90 + 1 set of new DLP90, and 2 sets of old DLP67), I suspect that the new DLPCR900EVM board has some malfunction. The four other sets work fine with their own pairs.

Please let me know if there are other ways to try. We'll also consider to purchase another EVMs if necessary. However, if that's the case, we want to know if the defective EVMs can be replaced

Kind Regards,

Jejomar

Jejomar,

When did the customer purchase the board in question?  If they first reported it to you within the warranty period (90 days I believe for EVMs), then it will be able to be replaced.

Please enquire as to when the board in question was purchased (i.e. an invoice would be good).
