Part Number: DLPDLCR2010EVM

Hi, 

I have DLPDLCR2010EVM-PCB. Before powering it up, I detached the upper board "DLP board" and connected a 5V, 3A adapter to the board. Only one LED was on "SYSPWR". However, I noticed that U12, U9 and U1 were getting very hot. Hence I disconnected the power and found that U9 looks burnt (I am not sure). measuring the resistance between the positive and negative pins of the input, I found it 6 Ohms. This means that there is a short circuit somewhere. To measure the powers, I had to connect the power again and remove it within few seconds to avoid the heat. The measured voltages were: 
U1 = 1V6

U12 = 1V8

U17 = 0V8

As you can notice, these numbers are not as expected from the schematics. Do you have any suggestion? 

It was the very first time to operate the EVM!

Kind regards,

Anas

    Hi Brandon, 

    I replaced the DLP board with a brand new one then connected the LEDs as recommended to J2. The board works now and LEDs D15, D16, D5 and D7 turn on when the board is live and the projector is on. However, after connecting the board to my PC, the provided GUI tool recognized DLPC3430 as shown in the attached file but did not recognize either the DLPA2005, EVM software or the EVM firmware. Will it be possible to fix that?

    Thanks in advance.

    Kind regards,

    Hi Anas, 

    Do you have a DMD connected in addition to the LEDs?

    Thanks,

    Hi Brandon,

    No actually. I didn't connect it. I will connect it and try again.

    Thanks for your help.

    Kind regards,

    Hi Anas,

    No problem! The DLPC3430 shuts down when a DMD is not detected, so that is likely why you were not able to communicate with the DLPC3430 over the GUI.

    Thanks,

    Hi Brandon,

    But is it normal that the EVM software and EVM firmware are 0.0.0?

    Kind regards,

    Hi Brandon, 

    As the software did not recognize the EVM software nor the firmware, I tried to install the firmware on the external Flash memory I installed. Hence, I tried to do that through the software and I got these messages. 

    Unfortunately, this did not work. Do you have any idea how to solve this issue? 

    Kind regards,

    Hi Anas, 

    Were you able to connect a DMD in the system? Please try this an see if the EVM creates an image. 

    If you connect the DMD and no image is created by the system, you may have corrupted the image. To fix this, power the EVM on but do not flip the proj_on switch and try to re-download the image. 

    Thanks,

    Brandon

    Hi Brandon, 

    Unfortunately, this did not work. To summarize, the problem now is that the software does not recognize neither the EVM firmware nor the EVM software, is this normal for DLPDLCR2010EVM-PCB? 

    In addition, I am not able to install the firmware through the software. Finally, there is no image shown on the DMD even after re-downloading the image. I am not sure if the image is re-downloaded successfully as it is not shown in the software.

    Thanks in advance. 

    Kind regards,

    Hi Anas, 

    Thank you for your quick reply. Let me summarize this situation to make sure I understand everything correctly, as you have tried many different things to get your EVM working. I have not seen the firmware version read back v0.0.0 before and I do not believe this is normal. 

    1. You purchased a DLPDLCR2010EVM-PCB EVM from TI store or a distributor. 

    2. You tried to power on the EVM (without LEDs or a DMD connected) and that caused damage to the EVM. 

    3. You replaced the DLP board with a new board, and tried to communicate with the EVM. The GUI was able to read a DLPC3430 controller in the system, but the DLPA2005 and DLP2010 DMD was not recognized. 

    Where did you get this new DLP board? Did you purchase an additional DLPDLCR2010EVM-PCB, or did you fabricate your own board?

    4. You tried to install the DLPC3430 firmware on the external flash memory. 

    Can you detail the procedure for this? Did you remove the memory from the board? Where did you get the firmware to install?

    Thanks, 

    Brandon

    Hi Brandon,

    Many thanks for your reply!

    I bought an EVM from Mouser and powered it on without connecting any LED or DMD. Hence DLPA2005 blew up. Therefore I had to replace it by a new one and solder it to the board. In addition, I bought another EVM from Mouser too. Hence, I have two EVMs now. After that, I connected both the LEDs and DMD and powered both boards on. The power consumption was around 105mA with the projector on. Connecting the boards to the PC, I found that the tool did not recognize neither the software nor the firmware of the EVM. This held for the PMIC and the ambient temperature fields in the GUI. I doubted , as there was no flash memory, probably the software and the firmware need to get installed manually on the flash memory. Hence I tried using the GUI Tool. This operation used to fail as shown in the previous attachments.

    Can you help me with this issue?

    Kind regards,
