DLPC3470: Firmware for combination of DLPC3470 and DLPA3000

aki

Part Number: DLPC3470
Other Parts Discussed in Thread: DLPA3000, DLP2010

Hello everyone

I prototyped the board using the following parts.
Controller: DLPC3470
Driver: DLPA3000

The controller farm of DLPC uses the firmware "dlp2010evm-lc_7.3.1.img" of DLP2010 EVM-LC-FW.

However, the board's boot sequence does not work well and [HOST_IRQ] from the DLPC remains high and does not fall low.
[PARKZ] and [RESETZ] from DLPA appear to have been entered successfully.

Is it possible to use "dlp2010evm-lc_7.3.1.img" for the DLPA 3000?

Hello,

You will need to obtain different firmware in order to use the DLPC3470 with the DLPA3000. Could you please confirm if there are any other changes made to your board? Specifically please confirm the controller to DMD pin mapping used.

Thanks,
Kyle

Hi Kyle

Although it is not special, I have control from the top with FPGA. There are also two output destinations to the DMD. (Do not use at the same time)

I would like you to check the created schematic if possible, but can I send it by e-mail etc?

Thanks

Hi aki,

Also, please ensure you're following PCB trace guidelines to avoid SI issues due to impedance mismatch. The guidelines are available here:
