10-pin 1.27mm ARM ECU14 Debug Adapter
|
The ECU14 connector and the pinout has been defined by Bosch. This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to ARM Cortex based target featuring a 10-pin 1.27mm pitch target debug connector with Bosch ECU14 pinout.
The debug adapter connects to the 25 cm 40-pin ribbon cable coming from the BlueBox and to the target debug connector on the other side.
|
This debug adapter supports only the JTAG debug interface. |
The following pinout is valid on the target side:

10-pin Bosch ECU14 target pinout
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
This Debug Adapter features resettable fuses on all connected pins. These protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away. Mandatory pins on the microcontroller side are GND, TMS, TDO, TDI, nTRST, TCLK and nRESET.
Pin 1 position
|
The pin next to the alignment pin is pin 10 and not pin 1! Pin is marked with a number 1 directly on the converter target connector. |
 |
|
The pin 1 position is marked with a small white square on the PCB. Additionally, the pin is marked with a number 1 directly on the debug adapter target connector from revision C1 on. |
|
Make sure this adapter fits on your target connector - check Cross Table. |
