Note: Be careful with Pin17 and Pin19. They are intended to carry the signals DBGRQ and DBGACK, when the Xtensa core is embedded into an Arm based debug environment (see Adaptation for Arm Debug Connector). Do not connect Pin17 and Pin 19 on the target side in other cases. Otherwise the hardware of the debugger can get damaged. Pin 2, originally intended to supply debugger hardware with power, is not in use and should not be connected to the target hardware either. Termination circuitry on the debugger hardware makes sure that these pins are not floating.

Target Connector Type

  • This is a standard 20 pin double row (two rows of 10 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 30.6mm/1.2".
  • Examples with housing: Samtec HTST-110-01-L-D (through-hole); Samtec HTST-110-01-L-DV (surface mount).
  • Examples without housing: Samtec TSW-110-23-L-D; Berg 67996-120H.
