50-pin ERF8 MPC5xxx Nexus
Some targets based on NXP MPC5xxx / ST SPC5 family can feature a 50-pin Samtec ERF8 connector for the Nexus debug interface instead of the popular 38-pin Mictor connector. In this case use and connect the converter to the target first and then connect the 38-pin Mictor MPC5xxx Nexus 16-bit Debug Adapter to the converter.
It has been noticed that the 50-pin Samtec ERF8 target connector may not always provide good mechanical stability in a vertical direction which can in worst case yield an unreliable debug connection. Special care must be taken when connecting this debug adapter to the target to prevent potential connection problems. |
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
The converter connects to the target via a 50-pin Samtec ERM8 connector, Samtec ERM8-025-01-L-D-EM2-TR. A target should feature a matching part, for example Samtec ERF8-025-05.0-L-DV.
Make sure this adapter fits on your target connector - check Cross Table. |
Refer to Hardware Setup and Configuration Tutorial to get more information on how to connect the hardware. |
The following pinout is valid on the target side:
