Every thing is fine. I want to thank Mr. Wolfgang Denk and all the people who contributed to u-boot. My interested is to boot Linux on this board. I downloaded linux-2.6.6. I followed EST8260 board in the kernel and made changes accordingly for my board. I did not add board define in "arch/ppc/boot/simple/embed_config.c" because u-boot-1.1.1 passes clock speed in Hz and so as the kernel versions from 2.4.5 (DULG FAQ) accepts in Hz. After successful compilation. I tried to boot the kernel. Here I am encountering problem with serial console. We are using serial port on SMC u-boot baud rate is set at 115200. I am using hyper terminal for serial console. Before booting the kernel, my display is ok. I can interact with the console normally After uncompressing the image and before loading the Linux. Many characters are skipped, And display can not be interpreted. I tried to change the baud rate using "setenv baud rate 9600". But u-boot in hanging. I am pasting the text capture for your reference. kindly help in overcoming this Issue. Does reducing baud rate helps? Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ...
