AM335X Bootp of u-boot-spl.bin followed by tftp of u-boot.img. Is it possible?

I am working with a board with the AM3352 that only has ethernet and a
serial port (UART0). I am able to use the bootstrap of the AM3352 to
network boot the u-boot-spl.bin file. I can't get the second stage
u-boot.img to network load via TFTP. My spl image says there are no
etjermet devices found.

1) My first question, is TFTP booting u-boot.img possible with the AM3352?

2) If it is, any thoughts on how I get u-boot-spl.bin to use ethernet for
loading the second image?


With some debugging enabled (I deleted all the memory allocation print
