Can I put an EFI boot partition on the MMC that will boot your latest version of Ubuntu off an SSD drive?
I am currently using a mini USB stick boot inside of the Joggler to boot the SSD to Linux.
I want to leave the wireless USB stick inside and just boot from the mmc to the SSD.
Can I just copy the EFI boot directory on the USB stick stuff over to the MMC EFI boot partition?
boot.nsh reads
fs1:
grub
startup.nsh reads
fs1:boot2
fs0:boot
grub.cfg reads
loadfont /unicode.pf2
terminal_output gfxterm
set timeout=5
menuentry "Xubuntu 14.04 LTS (Trusty) - 3.2.69joggler1" {
linux /vmlinuz-3.2.69joggler1 root=LABEL=linux-root ro quiet splash
initrd /initrd.img-3.2.69joggler1
}
would I break my Joggler doing this or will it still boot from a USB stick if I disconnect the SSD drive?
I have put your server base on the 2Gb Openpeak device and it runs fine.
Could I just put the server base on the Joggler MMC and change the grub cfg to boot main OS from the SSD instead of the MMC?
Trying a bit to shrink down the Ubuntu base to maybe copy it. So far looked at the MMC space.
Disk /dev/mmcblk0: 1028 MB, 1028128768 bytes
4 heads, 16 sectors/track, 31376 cylinders, total 2008064 sectors
Units = sectors of 1 * 512 = 512 bytes
Then current Ubuntu partition shrinking got it to 1002.98 Gb
This is taking me to when I played with XBMC running on the OF2 with the 2Gb.
Thinking of maybe trying to thin it out even more and maybe doing a dual boot; little Ubuntu big Ubuntu thing maybe?
Created a new SSD boot image using the new posted Ubuntu image. Works with a USB stick EFI boot partition as before.
Next wondering now if I wipe out the MMC EFI boot partition if I can still boot with a USB stick?
Does the primary EFI boot ROM look only at the USB stick first then MMC boot partition next?
