Hi all! I have adapted barebox for work with picotcp network stack. Picotcp is not a small piece of code so I can't easyly send a patch to the barebox maillist. I have put results of my work on github, see mini-howto below. This picotcp integration is a dirty hack in many ways. We need additional effors for adapting barebox and picotcp for more easy joint operation. Please express your opinion on my work. I'm awaiting your comments. Many thanks to Alessandro Rubini for his pointing on picotcp! barebox picotcp mini-howto ========================== 1. clone and build sandbox barebox $ git clone https://github.com/frantony/barebox -b picotcp.20140525 ... $ make sandbox_defconfig ... $ make 2. run sandbox barebox # ./barebox 3.
