| 24 | |||
| 25 | h4. 3-pin UART header |
||
| 26 | |||
| 27 | 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: |
||
| 28 | |||
| 29 | |_.Pin|_.Signal| |
||
| 30 | |left|P0 [1] / URX| |
||
| 31 | |center|GND| |
||
| 32 | |right|P0 [0] / UTX| |
||
| 33 | |||
| 34 | 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. |
||
| 35 | |||
| 36 | h4. 2-pin jumper |
||
| 37 | |||
| 38 | 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: |
||
| 39 | |||
| 40 | |_.Pin|_.Signal| |
||
| 41 | |left|GND| |
||
| 42 | |right|P2 [5] / ADC1| |
||
| 43 | |||
| 44 | h4. Row of large test pads |
||
| 45 | |||
| 46 | 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: |
||
| 47 | |||
| 48 | |_.Pin|_.Signal| |
||
| 49 | |1 (left)|P2 [5] / ADC1| |

| 60 | 1 | laforge | h2. Open Source Tarball |
| 61 | |||
| 62 | 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. |
||
| 63 | |||
| 64 | h2. building |
||
| 65 | |||
| 66 | It can be built on a current (Debian 11) system, if you install the following dependencies: |
||
| 67 | |||
| 68 | <pre> |
||
| 69 | apt install genromfs build-essential default-jdk gcc-multilib lib32z1 |
||
| 70 | dpkg --add-architecture i386 |
||
| 71 | apt update |
||
| 72 | apt install liblzo2-2:i386 |
||
| 73 | </pre> |
||
| 74 | |||
| 75 | After that, you shoul be able to compile it using the instructions from the README_BUILDING file that's in the source code. |
