I got the U-Boot prompt on my serial console now. The problem was with setting of one of the display clocks. However, I still get stdout: serial. I am trying to setup JTAG debugger to debug the U-Boot and see what is happening. Meanwhile, I looked at the console.c file and it seems like the overwrite_console() function must be returning 0 (because I have define CONFIG_CONSOLE_IS_IN_ENV ). But in the console_init_r() function, my lcd device is not found probably so it is using serial as stdout. Does it mean my device is not being registered with U-Boot framebuffer? I am using the common lcd.c and lcd.h files for common functions like registering the device etc. and am defining my board specific routines in a different file. Any help is greatly appreciated.

Thanks, Jigisha

I realized about the Bad CRC warning afterwards. Anyway, the U-Boot hangs

Are you sure that it hangs? Do you have the LCD display connected? What do you see on it.

after that message and I do not see stdout, stdin and stderr that should come up on the console. How can I change that to my target LCD?

I know that stdin cannot be LCD, it has to be UART, But how can I change stdout to LCD? Can any one help?

Read the code. If LCD is enabled, both stdout and stderr will go to the LCD by default - which is probably why you don't see anything so you think the board is hanging while it's running fine.

Try typing a few times ENTER, followed by a "setenv stdout serial" (even if you don't see any echo for your typing).
