h1. Gigaset Elements Base This is a DECT [[ULE]] base station for a variety of _IoT_ style devices such as burgler alarm, switchable power sockets, etc. FIXME: External Pictures h2. Hardware * Dialog SC14452 CR16C based DECT SoC * Dialog LMX4181 RF frontend * Winbond W9825G6KH-6 RAM * SMSC 8720A Ethernet PHY * MX25???

Connectors / Test Pads h4. 3-pin UART header There is an unpopulated 3-pin 2.54mm header on the board. It has the following pin-out, in left-toright direction when looking at the component side of the PCBA with the ethernet jack facing downwards: |_.Pin|_.Signal| |left|P0 [1] / URX| |center|GND| |right|P0 [0] / UTX| The voltage of the UART is about 3.2V; the data sheet states up to 3.45V should be fine, so a normal 3.3V UART should work. h4. 2-pin jumper There is an unpopulated 2-pin 2.54mm header on the board. It has the following pin-out, in left-toright direction when looking at the component side of the PCBA with the ethernet jack facing downwards: |_.Pin|_.Signal| |left|GND| |right|P2 [5] / ADC1| h4. Row of large test pads There is a row of large (3mm?) test pads close to the unpopulated 3pin header / 2pin jumper. It has the following pin-out, in left-toright direction when looking at the component side of the PCBA with the ethernet jack facing downwards: |_.Pin|_.Signal| |1 (left)|P2 [5] / ADC1| |2|6.5V voltage input| |3|GND| |4|P0 [1] / URX| |5 (right)|P0 [0] / UTX| h4. test pads on the back side FIXME: Picture with annotations. So far we know the single-wire JTAG pin. h2. Open Source Tarball In remarkably good compliance with the GNU GPLv2, Gigaset has published a tarball containing the _complete and corresponding_ soure code for the open source parts of the firmware. h2. building It can be built on a current (Debian 11) system, if you install the following dependencies: <pre> apt install genromfs build-essential default-jdk gcc-multilib lib32z1 dpkg --add-architecture i386 apt update apt install liblzo2-2:i386 </pre> After that, you shoul be able to compile it using the instructions from the README_BUILDING file that's in the source code. h2. flashing <pre> HomeConnector_001.000.026/uniprog $ ./uniprog.sh Creating empty file: size 0 kB file: 'reef_boot_rec_sys_fs.bin' Inserting image file: file 'image452.bin' at offset 0 size 131072 Inserting image file: file '../reef_vmlinuz-recovery' at offset 131072 size 819200 Inserting image file: file '../reef_vmlinuz' at offset 950272 size 2560000 Not creating new filesystem image.
