    Viet Dinh
    Abhishek, The diff between the 2 is the AM3871 does not have the HDVPSS display subsystem where as the AM3872 has. So, if you don't need HDVPSS, the AM3871 is closest to AM3872 you can get. BR, Viet

    Hi, Based on some other postings in the forums, I think we can just pull up the EMU0 and 1 pins if we are not planning on using them to debug. However, we are not convinced if we need them or not. I was reading the TI wiki (link and snippet below) on the XDS100-class emulator function, and it seems...

    Hi, We are testing a LCD module on DM814x EVM. the LCD requires negative HS and VS signals. but DM814x EVM provides positive HS and VS signal once we modified timing follow VPSS Video Driver User Guide. So my question is, is there anyway to modify polarity of HS and VS signal with sysfs?

    Hello, We want to be able to test the external board characteristics of the PCIe traces as well as the daughtercard design (FPGA portion). The TRM (sprugz8a.pdf) lists on page 2121 that the PHY supports a loopback in RC Mode. Is this for the internal software testing within the device, or can we use...
