| 10 | * DBB: Ti Calypso Baseband, D751749ZHH model (Calypso Lite G2), includes 256kBytes of internal SRAM |
||
| 11 | * ABB: Ti TWL3025BZ |
||

| 23 | === Test points === |
||
| 24 | |||
| 25 | There are some easily accessible test points (i.e. bigsqare and not very small round pads behind the rf shields). |
||
| 26 | |||
| 27 | Theses test points are divided in two groups (when looking from behind the phone) : |
||
| 28 | |||
| 29 | * A group of 7 TPs at the lower left of the PCB. Accessible from the battery compartment without disassembly except for the first one. From left to right : |
||
| 30 | * '''TP16''': JTAG TDO |
||
| 31 | * '''TP9''': CTS MODEM |
||
| 32 | * '''TP13''': TX MODEM |
||
| 33 | * '''TP14''': RX MODEM |
||
| 34 | * '''TP3''': DL PWR |
||
| 35 | * '''TP107''': GND |
||
| 36 | * '''TP19''': VBAT |
||
| 37 | * A group of 5 TPs at the middle/upper right of the PCB. Theses are not accessible without disassembly, but could be by cutting a small plastic strip just right of the hole made for the battery connector. From left to right: |
||
| 38 | * '''TP18''': JTAG TMS |
||
| 39 | * '''TP20''': BAT_TEMP |
||
| 40 | * '''TP17''': JTAG TCK |
||
| 41 | * '''TP15''': VCHG |
||
| 42 | * '''TP8''': JTAG TDI |
