[Cai, Chuntian (GE Transportation)]

Hi Rossi,

Could you tell me how to make uRamdisk.image.gz with YOCTO toolchain.

Thanks.

Since you are using poky, I suspect you might be getting a large percentage of your sources from the poky source mirror. This is fine, but it means that you only need to do http downloads even for some of the recipes that have git sources.

I have seen issues with proxies before for kernel repos, this is due to the large pack files that git attempts to retrieve. And the delayed time it takes to compress the pack files on the remote which some proxies timeout on. Sometimes using a different protocol works better that others. Try to clone the repo outside of yocto. Also try the different protocols if one fails. e.g.

git clone https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_Xilinx_linux-2Dxlnx.git&d=CwIFaQ&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=Ei3floKgst6PhYpovUjTVlWwDEc4CVl_t-gxqM04eQY&m=nq8czs_U5UXDvXM4ciXRICgPDdXYu7ElFGMISg-LHBI&s=x-ZWgWgfN-aaj3mudJuBFjg1KicY-DqWbbIpbJVqwhw&e=
or (ssh)
git clone git at github.com:Xilinx/linux-xlnx.git
or (git)
git clone git://github.com/Xilinx/linux-xlnx.git

If you find that one of these protocols work, change the protocol value in the linux-xlnx.inc recipe to use it (http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/tree/recipes-kernel/linux/linux-xlnx.inc#n12),
setting the "protocol" value to either https, ssh or git.

If you have no success with that, your easiest solution is to pull down the repo with proper access to the public internet, and bring it into your network (if permitted). Although I have limited understanding of your companies IT policies, so it would be in your best interest to contact your companies IT department for assistance, as this is an issue with the service they are maintaining for you.

If you do get the repo cloned outside of yocto, you can bring the repo in manually. The following should work assuming you replace the paths with those appropriate to your setup.

git clone --mirror <path to local linux-xlnx clone> <path to yocto
build>/downloads/git2/github.com.Xilinx.linux-xlnx.git

Due to the way the recipe functions it relies on the git repository.
So it would require some work to make it operate with just the working tree source that you can get when downloading the zip from github.

Nathan

Which is why you are getting a "Connection reset by peer" error from git. You will need to figure out what setup you have for your company and then configure access to the internet via a proxy or pre-download the sources and transfer them to your internal machine.
