1. To poky/meta/recipes-core/images/core-image-minimal.bb<https://urldefense.proofpoint.com/v2/url?u=http-3A__core-2Dimage-2Dminimal.bb&d=CwMFaQ&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=Ei3floKgst6PhYpovUjTVlWwDEc4CVl_t-gxqM04eQY&m=lMGlFDCNiCakR9W8kBbZHK2NLyOPyjP-Y3DFkHI9-JE&s=wuhk-KkTThAj7xDj8W8iExGuKFBpAB57nWw2xMZYwno&e=> add:
IMAGE_INSTALL_append += " \
mtd-utils \
mtd-utils-misc \
"
2. Or create a core-image-minimal.bbappend file in the meta-xilinx layer and put the text above there.
3. Or create your own recipe - example: core-image-elphel393.bb<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_Elphel_meta-2Delphel393_blob_master_recipes-2Dcore_images_core-2Dimage-2Delphel393.bb&d=CwMFaQ&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=Ei3floKgst6PhYpovUjTVlWwDEc4CVl_t-gxqM04eQY&m=lMGlFDCNiCakR9W8kBbZHK2NLyOPyjP-Y3DFkHI9-JE&s=ZV_lig-vczuQfDSKrlC9XjJSNVnzh-io3KDaRsWUu2Y&e=>

Hi Rossi,
I want use mtd-utils to test MTD dirver, could you tell me how to install it when I build rootfs.
My board is ZC706 and I use bitbake core-image-minimal make uboot,uimage and dtb
Thanks.

Hi,
"uramdisk.image.gz" is just another name for "*.cpio.gz.u-boot" (or any initramfs/initrd format e.g. ext. Which is gzipped and wrapped with the u-boot image header).
All meta-xilinx machines are setup by default to generate the *.cpio.gz.u-boot for the images you build. You can get other formats like ext.gz.u-boot, etc by adding them to IMAGE_FSTYPES (http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/tree/docs/Rootfs).
If you want it named as "uramdisk.image.gz" renaming it to that when writing it to the sd card/etc is sufficient.
Regards,
Nathan

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.

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.

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.
