Dear All, I need some advice on the data transfer from the C3088 cmos camera to the 8MB SDRAM of the C6713 board EMIF. Firstly can we use the GPIO to transfer pixels to RAM or do we need to use the EMIF for DMA allocation? We need to transfer the data pixel by pixel, not frame by frame, since we have 16 YUV pins from the camera going into the board as 16 external interrupts. Can you tell...

Hi all: Before plugging my card to pci slot, I tested it in EMIF boot mode through JTAG port, all the chips worked very well. But when I test the card in pci mode (using the EVMDM642 example pci drvier SIC6XWDM.sys and test app in "\\ti\boards\evmdm642\examples\pci" ), all operations of writing to/ reading from DM642 registers and IRAM seem ok, but just can't operate SDRAM. I didn't use ...

hi, i use dsk6711 with network daughtercard and the network example Filexfer from ndk/examples, i want that the running filexfer example loads a new .out file and stores it to the sdram. And finally jump to the new .out file and run it. 1.do i have to load a .out-file or a .hex-file? 2.how can i store it to a place in sdram? 3.how can the dsp jump to the new .out-file and run it? than...

Hello, I am trying to use an already existing DSP BIOS project built for C67xx and migrate it to be usable in C64xx. In the C67xx project there is SDRAM configuration present under the EMIF settings. In case of C64xx there is EMIFA and EMIFB. I want to be able to delete the SDRAM configuration from under EMIF settings and add new configurations under

TI showing example of secondary bootloader to copy code from Flash to SRAM and SDRAM. It seems that the code copy word by word from flash to SRAM and SDRAM. Isn't it more efficient to use DMA to move big blocks. How does one do this if DMA is to be used instead of copying word by word. ;* ------------------- File: boot.asm ------------------------------- ----* .title "...

Hi All, We have a DM640-based custom board with CPU operating at 400MHz. This board was working fine. Now we have replaced the DM640 with DM642-720 chip. The input PLL clock is same, i.e. input PLL clock is 33MHz and DM642 CPU is also running at 400MHz. Is this fine? We are trying to access SDRAM using the same GEL file as used for DM640 board. Since we have not changed any cloc...

Hi All, I am using C64x processor. I am having 32-bit SDRAM and 16-bit FIFO as external memories which are connected to DSP through EMIF. As C64x DSP has 64-bit EMIF bus width, I have connected pins D0-D31 to 32-bit data bus of SDRAM and pins D32-D47 to 16-bit data bus of

Hi all, I have created 32kbyte cache on dm642, and the other part is SRAM. When i use cpu filled a part of off chip SDRAM(bufferA) with some data, and then i use EDMA to transfer this data from bufferA to a part of on chip SRAM(bufferB), at last i use cpu to copy this data from bufferB to another part of off chip SDRAM(bufferC). The algorithm was like this, for(;;) { use cpu change ...
