CortexA15_0: GEL: File: D:\TI_WORKSAPCE\vps_loopbackExample_evmAM572x_armExampleProject\Debug\vps_loopbackExample_evmAM572x_armExampleProject.out: a data verification error occurred, file load failed.

    Hi,

    The VPS examples are built by makefile. First thing, please build the VPS using the makefile, following the user guide: software-dl.ti.com/.../index_device_drv.html, make sure that you can load and run it on AM572x EVM, so this is just the CCS project problem. Save your build log for reference.

    The CCS project is provided for very limited cases for reference. So far, only VPS loopback example for idkAM57x EVM are available. I am not sure where did you get "vps_loopbackExample_evmAM572x_armExampleProject" in pdk_am57xx_1_0_13. It doesn't exist!

    If you create this CCS project by yourself, please look at the same VPS user guide: How to create a CCS project other than VPS loopback example? It is most likely that you missed "In rtsc.setConfiguroOptions, add -DBOARD=<board_name>, which can be idkAM571x, idkAM572x, evmAM572x or idkAM574x". Please add this.

    If that still can't resolve your loading issue, you need to compare the CCS build log and makefile build log to see what the difference.

    Regards, Eric
