I think I figured out what was going wrong with my attempts on the ML507 board, you can specify a 16550 compatible serial UART (ttyS0), or the Xilinx UARTLite IP core (ttyUL0). So, because the correct serial console wasn't specified, I couldn't see the login prompt. I could see the boot progress on an LCD display, but didn't see the login prompt. The reason for asking was 'cos I remember that the core-image-minimal was more that 15mb a couple of months back, and now it has dropped to around 4mb, and I vaguely recall seeing a patch that resulted in its size reduction.

Best regards,
