We are looking for an http client now as well. Our major issue revolves around the download times for tftp. Can Volkmar Uhlig kindly provide the patches? Our units automically update themselves inside of uboot giving us the most control over our firmware. The issue is that it takes 20 minutes via a DSL line in Africa to update our units. An http test showed that the same firmware downloads in 30 seconds. We have also added things like the blksize parameter to the uboot tftp client to get it down to 20 minutes, our original download times were ~50 minutes. We would like to work to integrate or add the necessary http client functions to achieve this. If there are no patches obtainable, is anyone interested in working on this with us?

I am not so sure about that, but that's just my opinion. http://lists.denx.de/pipermail/u-boot/2006-March/013697.html but a simple client would be helpful in many situations. There is such in IBM's port of U-Boot for the Blue Gene super- computer, and Volkmar Uhlig promised to submit patches. But so far he didn't. Hmm.. That sounds interesting. Do you know if there is a public repository? or Do I need to buy a Blue Gene to get access to the source :) According to: http://domino.research.ibm.com/comm/research_projects.nsf/pages/kittyhawkindex.html/$FILE/Kittyhawk%20OSR%2008.pdf We added a simple HTTP server to U-Boot so that individual nodes can be booted via a PUT command that pushes the desired boot images and kernel command line. The command line is evaluated via the scripting environment before it gets passed on to the OS kernel thereby allowing per node customizations. With this simple extension to U-Boot we are able to construct powerful scripted environments and bootstrap large numbers of nodes in a controlled, flexible, and secure way. What is in RedBoot is a "HTTP GET". So -- while it shouldn't be hard to extend from there... If a port of the redboot functionality is done - any thoughts on if it would be accepted? Well, you are aware that such a thing would need a TCP/IP stack, which is far beyond what we currently have in U-Boot support? Yes - I'm aware. My thoughts were to do something like what IBM and other suggestions were - use lwip. -Robin _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot __________ NOD32 4266 (20090722) Information __________ This message was checked by NOD32 antivirus system. http://www.eset.com
