U-BOOT >bfin prompt 'u-boot-bf526-ezbrd-uart-2011R1-RC5'

After loading the latest u-boot release, u-boot-bf526-ezbrd-uart-2011R1-RC5 on BF526-EZBRD I don't get the >bfin prompt. I'm using the documented commands, is there a step I am missing? Output below.

SW1 is set to 8, the UART loopback jumper is removed and I'm using an USB to RS232 serial cable.


I also have a couple of questions if anyone can help.


-After U-Boot is loaded and the board reset, should U-BOOT respond to a Kermit connection with the bfin prompt?


-I want to boot out of SPI flash, after loading the u-boot SPI image is the UART enabled for TFTP kernal download?

You may want to run minicom or kermit now

Quick tip: run 'ldr <ldr> <devspec> && minicom'

Connecting to /dev/ttyUSB0, speed 57600

Escape character: Ctrl-\ (ASCII 28, FS): enabled

Type the escape character followed by C to get back,

or followed by ? to see other options.
