| 4 | This is s small PowerPC based embedded system. It communicates with the TETRA Site Controller (TSC) over 10-Base-2 Ethernet and controls all the other units of the Base Radio via the backplane of the BR cabinet. |
||
| 5 | |||
| 6 | It has the following connections: |
||
| 7 | |||
| 8 | * RS-232 on the back of the BR |
||
| 9 | * RS-232 on the front of the BR |
||
| 10 | * Site Alarm I/O on the back of the BR |
||
| 11 | * 10-Base-2 Ethernet on the back of the BR (BNC) |
||
| 12 | * Clock input on the back of the BR (BNC) |

| 19 | |||
| 20 | The hardware is a typical embedded design centered around MPC860 PowerPC: |
||
| 21 | * XPC860DECZP33C1 (MPC860 PowerPC SoC) |
||
| 22 | * User Manual: http://cache.freescale.com/files/netcomm/doc/ref_manual/MPC860UM.pdf |
||
| 23 | * Hardware Specs: http://cache.freescale.com/files/32bit/doc/data_sheet/MPC860EC.pdf |
||
| 24 | * BDM/JTAG: http://cache.freescale.com/files/netcomm/doc/app_note/AN2387.pdf |
||
| 25 | * Seems like P3 is the BDM/JTAG port for it |
||
| 26 | * 4x AM29LV017D (16MBit NOR Flash), total capacity = 8MByte |
||
| 27 | * http://www.datasheetcatalog.org/datasheet/AdvancedMicroDevices/mXwrvv.pdf |
||
| 28 | * CT2M64S4D10.8T66 (16MByte SDRAM module) |
||
| 29 | * NE83C92A coaxial Ethernet transceiver |
||
| 30 | * http://pdf1.alldatasheet.com/datasheet-pdf/view/17992/PHILIPS/NE83C92A.html |
||
| 31 | * XC56307GC100E (24-bit DSP56307 Digital Signal Processor) |
||
| 32 | * http://www.datasheetcatalog.org/datasheet/motorola/DSP56307.pdf |
||
| 33 | * Seems like P1000 is the OnCE/JTAG port for it |

| 35 | 2 | laforge | == Software == |
| 36 | |||
| 37 | === boot loader === |
||
| 38 | There is a bootloader pre-installed in the Base Radio. |
||
| 39 | |||
| 40 | === radio application === |
||
| 41 | It seems like the BR Controller is downloading its software via the Ethernet link from the [[wiki:Dimetra_EBTS/Site_Controller]] |

| 43 | == Console logs == |
||
| 44 | |||
| 45 | === Normal boot === |
||
| 46 | During normal boot, the console output is as follows: |
