i.MX6UL Initial Load

I have a board with a i.MX6UL processor. UART1 is the only serial boot interface connected on the board. I was wondering what the standard procedure for initially loading u-boot or a first stage bootloader (FSBL) onto the system is.

 

I can communicate with the chip through the serial download protocol but I am having trouble transferring a file of more than 2kB (the protocol just seems to stop responding).

 

I have tried using the program at https://github.com/boundarydevices/imx_usb_loader with little success.

 

The JTAG port is available on the board.

 

Any advice that could be offered on how to go about initial load would be greatly appreciated.
