I'm trying to build uclinux 2.6 kernel w/uclib for the 5272C3 eval
board. The board has 4M dram on it. I have dbug and u-boot running.
I downloaded the latest distro from uclinux.org <http://uclinux.org>.
I configured the board in "make menuconfig" for 0x00400000 of
available memory, memory starts at 0x0, and kernel start address as
0x20000.
I then "dn 20000 image.bin" from debug and then "g 20000"
Here is what I get:

You are basically out of usable memory.
Running a configured 2.6 kernel, with a largish root filesystem and on
a system with 4MB you are running our of RAM.
