Hi,I keep getting this error at the final stage of cpmplilation when the ZImage is begin created.THe erroris as follows:
SYSMAP System.map
OBJCOPY arch/arm/boot/Image
Kernel: arch/arm/boot/Image is ready
AS arch/arm/boot/compressed/head.o
arch/arm/boot/compressed/head.S: Assembler messages:

make: *** [uImage] Error 2
What could be the problem, please help
Oh, and by the way Thank a lot for doing this work it's helping a lot . Also do you by any chance have a detailed tutorial on how to port Linux kernel new Soc or a new processor or a given development board, and also the same for u-boot.
Thanks
Hello Friend,
I'm trying to build stock kernel from your linux-k70 bsp. When i entered /projects/networking directory and execute make iam getting this error output

bc package at latest version, how do i fix this error ? thanks a lot of.
Hi,
fb.c was last updated here 676994c with the comment
doesn't work yet
What is the status? Are you planing to fix it? If not, can you give any hints on what is left to do?
Thanks for your help!
Cheers,
Francois
Hi,
I was wondering whether there are any plans to integrate this work into the mainline kernel, or at least port it to a more recent version of Linux.
I tried to compile the sources for Cortex-M4.
It's my first attempts and I really confused... I started with `make menuconfig' where I disabled MMU-options and chose STMicro STM32 processor. Then I lunched 'make' and got these errors.

Hello Dear, thanks a lot of for uCLinux,
I was tried to boot Linux to our TWR-K70F120M Development board. I applied all requirements from your Linux Kinetis BSP Guide for the Freescale TWR-K70F120M Board pdf's . That include(code warrior, elevator modules setup, debugger options, flash operations) etc.
So i prepared Linux System for building u-boot from source code and i can compile u-boot. I successfully flashed to u-boot file to FLASH but problem is when i flashed to u-boot to our development board i see "HARD FAULT exception" on RS232 Serial of elevator serial module.
All u-boot prints listed below. I tried prebuild u-boot image too. But same problem occuring. What's is wrong is here?. Is that jumper or hardware fault?. What can i do? Thanks you.

The default configuration is unknown, so compiling the kernel requires a lot of additional knowledge. Can you please add a defconfig for the lpc1850?
Hi, I'm to use this kernel for the a2f-actel-dev-brd platform. The kernel build sucessifully, and load using u-boot. I've build busybox 1.16.0 sucessifully and update my initramfs-list-min file with basic character devices in /dev i.e console and the necesary $slinks for the busybox including /bin/init, but I keep getting the above error.
Please help
