DM816x development: EZSDK or PSP?

Hi,

I am new to 816x development. I started with Linux PSP for TI81XX, then I realized that it didn't include root filesystem.  I also noticed that there is the EZSDK for DM816x processors.  Here are my questions:

Q1. How can I build the root filesystem to be used with the kernel included in the PSP?

Q2. Should I use EZSDK instead?  Is PSP a part of EZSDK, or they are different products?  It seems the latest PSP 04.04.00.02 is slightly newer than the latest EZSDK 5_05_02_00.   For the time being, I only need basic features, such developing software for ARM and accessing DSP using syslink, and no need for QT or SGX.

Thanks,
tamo2

    Just to add that with EZSDK you can use two types of root file systems:

    1. EZSDK file system

    2. ARAGO minimal file system

    WIth PSP only, you should use ARAGO minimal file system.

    These file systems are available at:

    ~/ti-ezsdk_dm816x-evm_5_05_02_00/filesystem/ezsdk-dm816x-evm-rootfs.tar.gz and arago-base-tisdk-image-dm816x-evm.tar.gz

    More information you can get from the following documents/sites:
