CCS/DLPDLCR2010EVM: Projector no longer streams HDMI after the MSP430 is programmed with the sample code

Part Number: DLPDLCR2010EVM

Tool/software: Code Composer Studio

Hello,

I'm working with a DLPDLCR2010EVM, and I want to understand and modify the firmware on the MSP430. I've downloaded the MSP430 HDMI sample code (DLP2010-MSP430-SW) from the product page, and programmed it with an MSP-FET flash emulation tool. After loading this sample code, the projector still turns on and shows the splash image, but it no longer streams HDMI. My laptop can't detect the projector anymore. This module was working fine before I programmed it.

It seems like the code that enables the HDMI receiver chip (ITE6801) is missing from the sample code. What changes do I have to make to the sample code to get the projector to stream HDMI? Is there a copy of the original code that came with the EVM?

Hello Andy,

Could you please confirm what version of firmware you have on the 2010 EVM?

Thanks,
Kyle

Hi Kyle,

Thanks for the response.

DLP2010-MSP430-SW was downloaded just now, V1.0

The DMD flash image was also downloaded just now, V3.0.0

Uncommenting the following code on line 4162 in ite680x.c causes my laptop to recognize the module, but it still doesn't stream HDMI, it just shows the splash screen.
it6802HPDCtrl(0,1); // MHL port , set HPD = 1

Hi Andy,

I tested the sample code available on ti.com on my EVM and HDMI input is detected automatically. Can you list the exact steps you followed to build and load the sample code onto the MSP430? Moreover, have you made any changes to the code?

Regards
Azad

Hi Azad,

I've downloaded the code again and reprogrammed the projector, it seems to work now. For some reason it wasn't working yesterday.
