Hi all, I'm using u-Boot 0.4.0 with our custom board based on IBM walnut. I noticed that if I do not have the HyperTerminal running, the boot process never proceeds.
If I power up the target with out HyperTerminal running, it never comes up. As soon as start HyperTerminal, I see print out for Kernel download and the board boots up. It looks as though it was waiting for the serial communication before it starts downloading the kernel over the ethernet.
Is this normal behavior? Is there a way to make it boot up regardless of whether a serial terminal is connected or not?
Hi,
did you by any chance enable CONFIG_SERIAL_SOFTWARE_FIFO ? In that case the driver uses CTS/RTS handshake, which would explain your problem.
