Hello everybody, I would like to have some indication about the implementation of a MPEG4 codec on DM642 DSP. I think I will start my job from XVID codec, is there someone that can evaluate the complexity of this task? How many month can I need to accomplish this task (I'm not a super expert DSP engineer)? Any suggestion/advice will be appreciated. Thanks a lot also for any link that can pr

Hi, I have problems configuring the I2C module... When the DM642 is reset, it is not possible at all to write anything to the I2C registers, all registers remain 0. Whatever function of the csl-I2c I call, the registers remain 0. It seems that the I2C is

I have run into an issue on one of my boards (custom) where the DM642 will assert multiple reads without dropping any of the CEn signals. This happens when the DSP supposedly reads from CE3. I have tried both a mem-copy and EDMA with the same results on this particular board. Other boards work fine, but this one does not seem to drop the CEn signal. It does on test code, but not my "full up"...

Since I have never done this before, I nearly have no idea where to make this device driver to FX2 from DM642. Is there someone who had been familiar with it? Please give me some pieces of advice or references. Thanks in advance!

I'm using the PCI bus on the DM642 and I've been having a rather annoying problem with PCI_xferTest() saying that a read DMA is done, but the data doesn't check correctly. However, if I check the data a second time, it will be magically correct. It seems that even though PCI_xferTest() returns 0, the data hasn't actually made it to memory. So doing a read
