We're using a variation of it developed by Emcraft for that very same chip.  It 
currently only uses the M4 portion, but it has worked pretty well for us.  The 
source code is located at: https://github.com/EmcraftSystems/linux-emcraft

We also used their expertise to perform a few modifications specific to our 
project.  I hope that helps get you started.

Thanks,

Doug Brainard

Subject: [uClinux-dev] boot uClinux from a Cortex-M should be simple

Hi everyone,
I have been working with uClinux on a microcontroller with Cortex-M4/M0, 
specifically with LPC4357.
I have to say that I have previously worked with embedded linux, and in this 
project I managed properly configure and compile the kernel.
However I am not able to boot uClinux. I think the easiest way is to load the 
u-boot directly to the RAM, because I had problems when I tried to boot the OS 
from iflash, flash, spiflah, emc8, emc16 or emc32.

All opinions interest me to try to solve the problem. In principle I would like 
to boot into core Cortex-M4 and Cortex-M0 in'll try to install another OS more 
primitive.

Thanks in advance!

Sincerely,

Cristobal
