 Here it is the binary and the source code of **{{:doc:appunti:hardware:lacie:eeprom_write_byte.tar.gz|eeprom_write_byte}}**.
+===== The EEPROM =====
+With a proper kernel (2.6.32 with the above patch, or 2.6.37) the EEPROM content is exposed for read and write via the pseudo file **''/sys/bus/i2c/devices/0-0050/eeprom''**. This is what I know about its content:
+^ Offset  ^ Length  ^ Content  ^
+|       0 |       6 | Ethernet MAC address.  |
+|       6 |       1 | Power flag.\\ If set to **''LACIE_POWER_OFF''** (0), U-Boot will stop the boot process and wait for Wake-on-LAN.\\ If set to **''LACIE_POWER_ON''** (1), U-Boot will reboot.  |

 ===== Compiling the Linux kernel =====
+You can download the kernel I compiled (vanilla with patches for LEDs) here: [[http://www.rigacci.org/pub/Linux/kernel-lacie/]]
 After several tries, I compiled a **2.6.32 kernel** suitable to boot the LaCie from an **ext3 Debian Lenny partition**. No initrd is required to boot (this is fortunate FIXME, because I don't know how to install initrd with U-Boot). Here it is the **[[http://www.rigacci.org/pub/Linux/kernel-lacie/config-2.6.32-lacie.0.10|config file]]**.

+===== Backporting minidlna =====
+We run **Debian 6 Squeeze** on our LaCie d2 Network and we want it to be a [[wp>Digital_Living_Network_Alliance|DLNA]] server. We choosed [[https://packages.debian.org/search?keywords=minidlna|minidlna]] because it is targeted to embedded systems. The package exists for **Debian 7 Wheezy**, so we have to backport it.
+Into a **[[..:prog:qemu_arm|Qemu armel virtual machine]]** we installed the packages required for Debian developing and build dependencies, we need also debhelper from backports.
+<code>
+apt-get install build-essential dh-make debhelper dpatch
+apt-get install libavcodec-dev libavformat-dev libavutil-dev libexif-dev \
+    libflac-dev libid3tag0-dev libogg-dev libsqlite3-dev libvorbis-dev libjpeg-dev
+wget http://ftp.at.debian.org/debian-backports//pool/main/d/debhelper/debhelper_9.20120909~bpo60+1_all.deb
+dpkg -i debhelper_9.20120909~bpo60+1_all.deb
+</code>
+Then we downloaded the minidlna sources and compiled the sources:
+<code>
+mkdir /usr/local/src/minidlna
+cd /usr/local/src/minidlna
+wget http://ftp.de.debian.org/debian/pool/main/m/minidlna/minidlna_1.0.24+dfsg-1.dsc
+wget http://ftp.de.debian.org/debian/pool/main/m/minidlna/minidlna_1.0.24+dfsg.orig.tar.gz
+wget http://ftp.de.debian.org/debian/pool/main/m/minidlna/minidlna_1.0.24+dfsg-1.debian.tar.gz
+dpkg-source -x minidlna_1.0.24+dfsg-1.dsc
+cd minidlna-1.0.24+dfsg
+dpkg-buildpackage -rfakeroot
+cd ..
+</code>
+The resulting **{{.:lacie:minidlna_1.0.24_dfsg-1_armel.deb|minidlna_1.0.24+dfsg-1_armel.deb}}** package installed fine into the LaCie, just make a symlink ''/run -> /var/run''.
+Configuration file is **''/etc/minidlna.conf''**, default share directory is **''/var/lib/minidlna''**, used ports are **8200/TCP** (http and media transfer), **3307/UDP** and **1900/UDP**.
