Hi,

I have a 6678EVM board , AMC-PCIe adapter card and DM8168EVM board, TI provide ubuntu desktop-linux-sdk and mcsdk_video_xxx package  based on the the pc machine, which can achieve the communication  between pc machine and 6678 through  AMC-PCIe adapter card .Now, I  want to use 8168EVM board instead of a PC to execute ./init_dsp.sh and the other operation on 8168.

1.Can it possible to achieve?
2.If it can achieve, how to cross-compile desktop-linux-sdk correctly?
3.If it can not be achieved, is there any other examples can achieve   transfer image files from 8168PCIe to 6678 and let 6678 run?

    Hello,

    For DM816x device, you can use EZSDK 5.05.02.00 (latest), available to download from http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html

    For which PCIe modes of operations are supported in the DM816x EZSDK (which includes PSP), check the following documents:
