Debugger and Trace Connectors


BDM Connectors for ColdFire V2, V3 and V4

  • The signals needed for debugging and tracing are combined in a single connector.
  • Some of the pins in the schematics below have multiple alternate signal names. Please check the "BDM Connector Pinout" chapter of the reference manual for the exact CPU you are using for further details or contact our support team.
  • The pins 2, 7 and 26 need a pull-up resistor on the target ranging from 1 kOhm to 5 kOhm.

  • This connector cannot be used for tracing, because the CPU variants with the ALLPST signal miss the necessary PST3..0 and DDATA3..0 signals.

Target Connector for ColdFire


Dimension

Connector Type

  • This is a standard 26 pin double row (two rows of 13 pins) connector (pin to pin spacing: 2.54mm/0.100").
  • If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 38.2mm/1.5".
