Currently, I am trying to build a linux image for my custom board with MCF5445x processor. I take M54455EVB linux image as a start point. I bootm the M54455EVB linux image from uboot (I use uboot-1.3.2). The uboot works well, the kernel booting hit the start_kernel(). But there is nothing output from console!!
With debugger, I saw that the printk() functions were called many times without any console output. Tracing into the kernel source code, I found that the printk() called "con->write" operation... Still puzzled.
Can anyone guide me to solve this?
