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?
Thanks
With some debugging enabled (I deleted all the memory allocation print statements):
Trying to boot from eth device env_driver_lookup: No environment driver for location 2 Using default environment Initial value for argc=3 Final value for argc=3 No ethernet found. No Ethernet devices found SPL: failed to boot from all boot devices
