I have a custom board with a SC589 and I've modified the ezkit uboot code and the board boots up fine and I can run through the entire "loading Uboot for the first time" process without a hitch. It detects my serial flash, dhcp works like a charm. and I can execute the update command in uboot and it all seems to go ok but when I power cycle the board I see nothing on the serial terminal. Environment variables persist across debug sessions.
I'm at a loss as to what could be causing this.
