custom board bringup issue

[devesh_nagar]

We are using imx7d with customized board. We connected board to our laptop via OTG cable. It is detected as "hiddev0,hidraw0: USB HID v1.10 Device [Freescale SemiConductor Inc  SE Blank ULT1]" device.
We are using 256x16 bit RAM (is43tr16256bl-125kbli).

We are trying to load u-boot from usb otg using imx_usb tool:
    $ ./imx_usb u-boot-dtb.imx
It loads binary to 0x877ff400 address, But fails when try to jump on 0x877ff400 address. We think some RAM configuration is required, but dont know how to do it. Let us know there could be any other problem. Please help us on this problem.

These are the logs of imx_usb tool:

Hi Devesh

usb_loader tool was developed and supported by third parties, it is not supported by nxp.

One can look at its description below and try to debug it using sources

Imx usb loader - Variscite Wiki 

GitHub - boundarydevices/imx_usb_loader: USB & UART loader for i.MX5/6/7/8 series 

Best regards
igor
