Bug#809611: d-i fails to boot on HP mv2120



Control: tags -1 patch

Hi

Dixit Martin Michlmayr, le 08/08/2016 :

>Please add the following to the release-notes on armel in the upgrade
>section:

[...]

I used copy&paste and formatting to put this in the Upgrading chapter.
I choose the integral doc, as it's not so long and clearer that linking
to Martin's webpage.
Please comment and correct.

+In most cases, packages should upgrade smoothly between &oldreleasename;
+and &releasename;.  There are a small number of cases where some intervention
+may be required, either before or during the upgrade; these are detailed
+below on a per-package basis.

+  <para>
+    The default u-boot settings from HP no longer work with &debian; &Releasename;.
+    Before you can upgrade to &debian; &release;, you have to change some settings
+    in the u-boot configuration. 
+    The new settings are compatible with &debian; &oldrelease; and &debian; &release;, so it's
+    recommended to make the changes before the upgrade.
+    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:
+  </para>
+  <screen>
+    setenv loadAddr 0x0600000
+    setenv bootcmd 'bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb'
+    saveenv
+  </screen>
+  <para>
+    If you don't have a serial console, you can make the changes from
+  within Debian. Run the following commands:
+  </para>
+  <screen>
+    cat &gt; /etc/fw_env.config &lt;&lt;EOF
+    /dev/mtd0           0x00000         0x1000     0x20000
+   EOF
+
+   fw_setenv loadAddr 0x0600000
+   fw_setenv bootcmd "bootext2 0,1:1,2 0x0600000 /boot/uImage /dev/sda /dev/sdb"
+  <screen>
+  <para>
+    This creates a config file so the u-boot environment can be modified
+    and uses <command>fw_setenv</command> to update two boot variables.
+  </para>
+  <para>
+    Please note that &debian; &release; will be the last release to support the HP mv2120.
