Hello:

 

The board I use is ezkit533(rev0.2),a very old one. But now I just can get this board. I have tried many uclinux and uboot versions. It seems that only the very old version, 2005 R3-RC3 can make the board start.

 

I have successfully booted that board,but when I download uclinux image kernel, there are still some errors.

 

  ezkit> bootm 0x1000000

All the things I have done when making menuconfig is cancel the support part of busybox. Because compling kernel fails when including busybox.The error message is:

I am quite sure 2005R3 supports my borad. Some one else has successfully compled one image base on this uclinux version. But I don't know the host linux distro. Does it  have much influence in compling kernel?

 

my environment:

 

gcc version 4.1.2 20070502 (Red Hat 4.1.2-12)

 

GNU Make 3.81

 

And I am confused that whether I should do some changes to kernel, in addition to the following step:

 

1. make mrproper;

 

2.make menuconfig  ,just cancel busybox and leave other options default.

 

3.make all.

 

Above all,I found the file      uclinux /romfs/etc/rc:

 

hostname blackfin

#/bin/expand /etc/ramfs.img /dev/ram0

mount -t proc none /proc

mount -t ramfs /dev/ram0 /var

mkdir /var/tmp

mkdir /var/log

mkdir /var/run

mkdir /var/lock

#dhcpcd &

#ifconfig eth0 10.100.4.251 up

ifconfig lo 127.0.0.1

inetd &

#cat /etc/issue

cat /etc/motd

 

 

While initalizing, the kernel do the instruction in this file, I just don't why it fails.

sorry, but your hardware and software are way too old and not supported.  you're on your own.

 

buy a newer ezkit and use the latest distro if you want support.
