DLPC410: not receive rst_active signal

Roy Messinger

Part Number: DLPC410
Other Parts Discussed in Thread: DLP9500

Hi,

Working with custom board and custom flex cable towards DLP9500 (controller is DLPC410ZYR, driver is DLPA200PFP, PROM is DLPR410AYVA).

I am receiving the init_active signal but after the frame is sent, not receiving any rst_active signal from the board. blk_md is sent as needed by the FPGA.

I've disconnected the DLP and flex cable, still receiving init_active from the controller, so obviously this does not help.

Any help will do. I'm currently stuck.

Issue resolved.

Part of the solution was the differentiation between Intel and XIlinx FPGA's. In my older board (Intel based FPGA) it worked well, and now in my new board (Xilinx), according to the following comment in the DLPC410 data sheet, I should have sent a different pattern:
