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=>

Subject: EXT: Re: uRamdisk.image.gz

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
