2.6.3 ARM 10-Pin Debug Header

An ARM 10-pin Debug Header (J7) is included on the LP-AM13E230 for connecting an isolated JTAG debugger to the AM13E230x MCU. This allows for flexibility in debugger hardware if an emulator other than the on-board XDS110 is desired.

To debug the AM13E230x MCU using an external emulator, the corresponding jumpers on J12 (denoted on the PCB silkscreen) must be removed in order to isolate the ARM 10-pin Debug header signals from the on-board XDS110:

  • TDI
  • TDO
  • TCK
  • TMS
  • Optional: RX and TX - still can be used to enable a serial interface to the connected USB host if needed

The pinout of the ARM-10 Header is as follows:
