Hi,
I uploaded my code n the web:
http://files.kooltek.net/linuxlpc24xx.tar.bz2
Could somebody have a look at it? I know there is some port fof uClinux for
lpc24xx, but this uses the 2.6 kernel, which is very old compared to the 3.x
kernel. It also doesn't use the device tree, but I would like

In cases like these I tend to search fo
ine-specific
initialisations (which reside in arch/arm/mach-* directory).

Hi everyone,
I am trying to run uClinux on an ARM7 LPC2000 chip from NXP. I have some
external SDRAM (64M) and Flash (8M). In the Flash, I plan to store the zImage,

which sets up the device tree and then boots the zImag
