Problem in booting the kernel

[Altera_Forum]

Hello everyone. I am a newbie in uclinux. 

 I follow the UClinuxDist in  http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist) compile the kernel and download it.   In the uart terminal, it's displayed  "Uncompressing Linux... Ok, booting the kernel." and nothing more.  I don’t know how the uclinux works.  Is there something wrong with boot process? Or I must use u-boot to boot the kernel? Or the setting of the kernel is not correct?   thanks!  The following is what i have done. I just want to test the uclinux on the sdram, so I didnot use the u-boot as smcnutt recommends. QuartusII 5.0, NiosII5.0 The board is UP3 (sls.com) with 2MByte flash, and 8MByte SDRam.  http://www.slscorp.com/up3support/tutorial...c6%20manual.pdf (http://www.slscorp.com/up3support/tutorials/up3-1c6%20manual.pdf) and I test the sdram and the flash with the design example from sls.com.  http://www.slscorp.com/up3support/tutorials/ref_design.zip (http://www.slscorp.com/up3support/tutorials/ref_design.zip)  First, I download and install the nios2linux-1.4.zip from the forum, and follow the “Linux Quick Start Guide.pdf” to compile the kernel under the nios2 IDE. It’s success. But I don’t know how to download it to ram.   Then, I compile the kernel following the instruction in UClinuxDist under Ubuntu http://nioswiki.jot.com/wikihome/operating...nux/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist) using uClinux-dist-test-20060511.tar.bz2 and uClinux-dist.diff.gz from http://nioswiki.jot.com/wikihome/operating...ux-dist.diff.gz (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist/uclinux-dist.diff.gz) and download the kernel in win-xp, with nios II SDK shell. It shows the zImage is download to 0x00500000. The display "Uncompressing Linux... Ok, booting the kernel."  Final, I try the method in  http://nioswiki.jot.com/wikihome/operating.../buildrootguide (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/buildrootguide) and build the kernel with: build0411.zip uClibc-0.9.29-pre,busybox-1.1.1-pre0 binutils-2.15.tar.bz2 gcc-3.4.6.tar.bz2 linux-libc-headers-2.6.11.0.tar.bz2 buildroot-20060320 uClibc-20060320 busybox-20060320 and the uart terminate display the same.

hi hammer 

If u want to run Linux on flash , then for store image into flash you have to store u-boot with some changes or u have to make new the sysem through SOPC builder with CFI-coponent. but just if u want to run linux from sdram ,then first compile kernel with required configuration as per“Linux Quick Start Guide.pdf” and then run it. it will boot through jtag console.     --First, I download and install the nios2linux-1.4.zip from the forum, and follow  --the “Linux Quick Start Guide.pdf” to compile the kernel under the nios2 IDE.
