Hi, For my new design I am planning to make DM642 as PCI system host. The system will consist of DM642 and USB controller with PCI interface. As there is no other processor required on board, I want to make DM642 as PCI system host. I have gone thru the datasheet and found out that DM642 does not generate IDSEL and it does not have PCI arbitra

Dear all, I want to capture the images using a camera and have to display it on a monitor/TV using dm642 EVM board. My idea to proceed with this is like below: connect the camera and configure one of the Decoder of dm642(dm642 has 2 decoders). I can choose and configure DM642 using I2C module. The output of the decode will be 4:2:2 YCbCr format. This is given to the video p

Yes, I have the same problem... reset remains 1. This can only happen when the clock signal is not present... but I have a really good clock on my DM642. So I switch-off-on and hope it works again.

Just wondering about a design I recently saw which had a DM642 interfaced to SDRAM using a 32-bit wide data bus. The SDRAM chip only has a 32-bit wide bus and the other 32 bits of the DM642 are not used. Not sure why it was designed this way as it only going to slow down the EMIF that much more. Can this design work? Is this going to be problem? Any special commands required on the DM642 to s...

Hello We've successfully built a board based on DM642 and we've interfaced an SDRAM DIMM module to DM642 over EMIF (MTYPE: 64 bit SDRAM). Has anyone tried this before. I'd like to know if there's any performance hit in using SDRAM DIMM modules versus using a standard SDRAM chips. If yes, how much. We're running DM642 at 600 MHz & SDRAM is configured at 100 MHz. Thanx & regards Gaut
