    Jon S.
    With the latest EZSDK release (5.04), my EVM fails to boot about 30% of the time with the following error, which causes the system to grind to a halt. (I've trimmed the path in the assertion for brevity.) Has anyone else seen this or know what could cause this? Loading HDVICP2 Firmware...

    Abhishek Gupta
    Hi, I am moving my code from C64x+ (on DM6437) to C674x (on DM8148 and J5). But the performance numbers were actually coming worse. So I tried to check the L1D, L2 and DDR access times. I have written a sample code to count the DSP cycles taken in doing a memory transfer between these memories. (I have...

    Dear all, I use the DVRRDK_03.00.00.00 and configure the 480P BT656 output to DVO2 on DM8148. However, the output will connect to a fpga that can accept the BT656 format. When I modify the HD_VENC_D_DVO2 register to 0x418 0 A031, the fpga can not recognize the video format. Can anyone give me some...

    Yes, if you want to write to memory in CCS, you have to freeze the CPU first. If you want to read, you can just do refresh. Regards, Viet

    Additional comment from our designer: "Apart from component cost (which could be higher for 2x16 configuration) there is no disadvantage in using 2x16 vs 4x8. 16x2 does help in having smaller footprint (on board) compared to 4x8 - which could be BOM saving."
