Honored Contributorlet me explain the question, after the iZmage boot in the Cyclone II designed as a custom board. the terminal only show the string.
Uncompressing Linux... Ok, booting the kernel no other message prompt Someone told me that the zImage contains the printk statement, if it booted successfully, it will show the message info. Thus, I considered that it would not like to start OK. --- Quote Start --- I usually debug kernel with printk (if any other method is impossible).... --- Quote End --- Thanks to carlob, would you like to give more details about debug the kernel. how to do it .I have never written the codes about the linux kernel. This was my first to compile the zImage files,and I have touched the uclinux kernel for about fortnight. Usually, I programmed in the NIOS2 IDE using the debug icon to trace the problem in real time, but for the kernel I did not get any ideas. So I appeal to acquiring some correlated advices or aspects below Any tools to debug the kernel,especial the zImage Is there any Virtual or analogue environment to debug the zImage Any method or procedure to build the enviroment to trace the error or problem. I would like to contribute my result to the web to help others who experienced this question like me.
