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"...

Hi all, I'm capturing 720p progressive video with DM642. I'm using the video port 4:2:0 horizontal resample. As it said in the user guide, the vertical resample is to do in software. Do you know any good solutions to do this during EDMA transfer or after frame transfer ? Any good ideas ? Thanks for your help

Good morning everybody, I would like to perform a software reset of a program on DM642. I tried to use c_int00(), and it does what I desire (I call it when uP host sebd me an ad hoc message), but I would like not to automatically start main() routine. In fact I would like to start the program through the HDCR register, bit DSPINT (controlled through a uP). How can I perform reset operations thr...

Hi All, Good morning. Kindly help me out in solving the problem. I am getting error after I disconnect the target DM642. I am not able to understand the error as there is no breakpoint SET. The error is as follows: " Failed to remove the debug state from the target before disconnecting. There may still be breakpoint opcodes embedded in program memory. It is recommended that you reset the...

Hello Everyone! I am relatively new to the field of embedded system design and am interested in doing a demo project that involves the DM642 board. My team and I are particularly interested in the development of a system that can process video in real-time for automotive, aerospace, defense, or semiconductor, and electronics type applications. We would like this project to be rep

Hi there: Recently I have worked on a project which uses FX2 slave FIFO from DM642. FX2 is Cypress CY7C68013(56 pin). 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!

Hi all, If there is any example which explains how edma is used to transfer between FIFO buffer and capture/ display buffers,Further how can we manage field/frame synchronization and capture/display timings using edma (i am not sure is edma the right choice to do that) on DM642 platform. If anyone has read SPRU629D document and understoo

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

Hi All, I am a newbie to this group. I have just started learning about DM642 and using the EVM board. I have few doubts that are raised from reading the documents from TI regarding the Video ports. Using Video port in raw-video mode, we would like to make 8-bit transfer with SUM=00 and DUM=11. The information coming in the video port is like

hi: recently, i encountered a problem during my dm642 developing. that is the i2c is out of work. when i run a demo program , the i2c's scl and sda pins are all high voltage. so the dsp can not communication with any other device . and the program is loop excuting in the i2cxrdy function forever.and check all i2c registers and perpherial registers , i found out that their value are all right ...

Hi, I use the EVM642 board with CCS 2.21. I try to configure port 2 DM642 as VGA display port (using CSL). I have taken the example in appendix B.2 of spru629.pdf as a base program to initialize the VP registers. When the board is power cycled, using my initialization, VP doesnt start outputting data, VDSTAT remains 0 (no line count...). When

Hello friend, After you set PEREN and VPCTL =0x8000 (reset), wait for (VPCTL&0x8000) ==0... if this takes more than 100.000 cycles, you have the same problem as I have... and I don't know the solution... just power-off-on and hope it works again. greetings, Bart > > Hi, > > I use the EVM642 board with CCS 2.21.

Hello, I have recently acquired a DM642 board from spectrum digital. I am currently trying to interface it with an KAC9637 CMOS active pixel sensor from Kodak. The sensor needs about at 27MHZ clock to run at top speed. I tried generating this clock via the TImer and the TImer output pins but was only

Hi, I am trying to communicate to a M25P32 SPI Flash from ST using the Mcbsp1 of a DM642 DSP, but I have some problems. There are some fundamental instructions in this flash where I need to send a command and wait for the answer (The READ, for example). In this case, in the same FSX low period, I need the clock signals first to send the instruction READ code and more three bytes of ad...
