Pinout of unlabled 26pin Header MOD 54415

Hello,
does anybody have a pinout / functional description of the 26pin unused header of the MOD54415 Board?
Maybe some of the pins can be used for more I/O to the processor.
Kind regards
Reinhard

These pins are specifically for the factory bring up (using a BDM). They cannot be used as GPIO for normal operations.

The header has some special pins and otherwise is a standard Freescale BDM connector...
Some of the pins can be put into GPIO mode, but we do not offer any software support for this nor do we recommend it...
However to answer the exact question you asked.....
PST0 CPU PIN J14 is pin 15
PST1 CPU PIN J15 is pin 14
PST2 CPU PIN J16 is pin 13
PST3 CPU PIN J13 is pin 12
DDATA0 CPU PIn L14 is pin 19
DDATA1 CPU PIn M15 is pin 18
DDATA2 CPU PIn M13 is pin 17
DDATA3 CPU PIn L15 is pin 16
On this connector Gnd is pin 3,5,11,20,23
VCC3V is pin 9, 25
26 is no connect...
Attaching to ANY OTHER pins on this connector will likely break your module.
