Mike, can you please give these instructions a go? This is what I
intend to post to the mv2120 list.
Mike Thompson reported that Debian stretch (the upcoming Debian 9)
doesn't boot on the HP mv2120 anymore. I don't know how many Debian
users are left who run Debian on their mv2120. I gave away my device
several years ago. Recently I bought an mv2120 from eBay in order to
debug this issue.
While I found a solution, it requires users to change a setting on their
device. Please make sure to make this change, otherwise your device
will no longer boot when you upgrade to Debian 9.
The new settings are compatible with Debian 8 (jessie) and Debian 9
(stretch), so I suggest you make the changes now.
If you have serial console access to the mv2120, you can run some
commands in u-boot. Simply interrupt the boot process by pressing a key
and type the following:
setenv loadAddr 0x0600000
setenv bootcmd 'bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb'
If you don't have a serial console, you can make the changes from within
Debian. Run the following commands:
cat >/etc/fw_env.config <<EOF
/dev/mtd0 0x00000 0x1000 0x20000
fw_setenv loadAddr 0x0600000
fw_setenv bootcmd "bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb"
This will create a config file so you can modify the u-boot environment
and use fw_setenv to update two boot variables.
Once you made the changes, upgrades to Debian 9 should work fine and you
can also use the Debian installer if you want to perform a new
Please note that Debian 9 will be the last release to support the HP
Note that the installer from
will not boot right now with these settings. However, you can change the
loadAddr to 0x0500000 and it should work. I just commited a fix in Git so
it should work in a day or so with 0x0600000.
