DLPC3430: DLPC3430 bring up

Part Number: DLPC3430
Other Parts Discussed in Thread: DLPA2000, DLP2010, DLPDLC-GUI

Hi there

      We are using DLPC3430 + DLPA2000 + DLP2010 combination for display. I selected the firmware from TI website like below combination. And download it to NorFlash which is connected to SPI0 of DLP3430 controller. After enable all the power supply of the chipset, the HOST_IRQ pin is never goes to low when I pull the RESETZ pin to high. This means the system is not boot correctly.

Question 1:

     Did I selected the correct firmware ?

Question 2:

     Because the firmware is end with .img extension. But my Jlink Flash tool can only recognize .bin file. So I modified the firmware extension name to .bin manully. Can this operation be allowed?

By the way, I flashed the firmware to address 0x0000 of norflash, is this begin address correct ?

Question 3:

     Because the DLP2010 DMD module is under production, So the system only contains DLPC3430 + DLPA2000 currently. Can DLP3430 controller boot correctly without DLP2010 DMD ?

     Any help would be much appreciated.

    Hello User,

    Welcome to the E2E forum and thank you for your interest in DLP® technology!

    So long as the pin-mapping and I2C address correctly corresponds to your system, this should be correct. In the case where the pin-mapping and I2C addresses are incorrect, HOST_IRQ should still be driving low but you will see a garbage image projected in the case of incorrect pin-mapping.

    Changing the extension from .img to .bin may make the firmware unusable though there are no functional differences besides the extension for these two file types.

    I am not familiar with Jlink but it may be able to handle .img files if properly searched for. If the tool truly cannot flash the image, I recommend going through the steps in the DLPC3430 Corrupted Flash Debug FAQ page for instructions on how to flash the image through our DLPDLC-GUI. There is also a link at the bottom of the page for flashing the device directly with an SOIC clip, though this is a more expensive and difficult procedure.

    Yes, this should be correct.

    No, the DLPC3430 will not complete initialization without a DLP2010 DMD. In this case HOST_IRQ will always drive high.
