Hi .
I try to test Angstrom RFS as ramrfs on BeagleBone Black, these are my steps:
-I get ramdisk.gz after compress with gzip this RFS:
*Angstrom-systemd-image-eglibc-ipk-v2012.05-beaglebone.rootfs.tar.bz2
*modules-3.2.42-r19b+gitr720e07b4c1f687b61b147b31c698cb6816d72f01-beaglebone.tgz
I use mkimage to do format at that file:
mkimage -A arm -O linux -T ramdisk -C gzip -d ramdisk.gz ramdisk.gz
I have use the last uboot image with this uEnvt.txt:
bootpart=0:1
bootdir=
loaduimage= load mmc ${bootpart} ${loadaddr} ${bootfile}
uenvcmd=run loaduimage;run loadramdisk;run findfdt;run loadfdt; run ramargs; bootm ${loadaddr} ${rdaddr} ${fdtaddr}
That’s the results:

¿Someone have do it that test with Angstrom like ramfs?
