Hey thanks for that.

Using my Sam460ex I downloaded the 2GB image, decompressed with 7za and wrote with rawdisk then booted linux in text mode from the USB thumb drive with no problems .
Seem to have to use MediaToolbox to Install the USB thumbdrive before the rawdisk copy .

rawdisk from Data:Downloads/Amigaone_Ubuntu_16.04-Base-1.img to usb0:

maybe from http://amiga.sourceforge.net/?showpackage=p7zip

I have encountered problems booting both AmigaOS4.1 and Linux with an EXT4 partition on my hard drive so have removed ub2lb as the bootloader and gone back to slb_v2.
ub2lb gets stuck and won't load the boot menu due to the EXT4 partition.
I now boot the kernel from USB thumb drive .
The new Uboot variables set from AmigaOS 4.1 are ( the example is with a root partition as the 8th partion on the hard drive so /dev/sdb8)

Code: Select all
nvsetvar bootargs="console ttys0,115200 console=tty1 root=/dev/sda8"
nvsetvar lb1="ext2load usb 0:3 1000000 uImage-460;ext2load usb 0:3 2000000 sam460.dtb;bootm 1000000 - 2000000"
nvsetvar bootargs_usb="setenv bootargs 'console ttys0,115200 console=tty1 root=/dev/sdb2 rootdelay=10' "
nvsetvar lb2="run bootargs_usb;run lb1"


To get to uboot command prompt quickly at boot hold down the escape key
From the uboot command prompt

To use the hard drive partition /dev/sdb8 as root
Code: Select all
run lb1


To use the usb drive partition /dev/sdb2 as root
Code: Select all
run lb2


The kernel is stored on the /dev/sdb3 partition of the usb thumb drive with the name uImage-460.
The partition type is EXT2 and you have to be root to copy on to this partition from Linux .

Used TFTPD (using vmware and a very plain/simple linux distro with tftpd-hpa) to load kernel 4.6.2 and worked fine and faaaaaast. Now I just have to remember what usr/psw do I have on my Ubuntu installation ¿:-/
