Intel DBPXA210, DBPXA250 7. For ARM* Multi-ICE* JTAG Use

DBPXA250 and DBPXA210 Development Platforms Specification Update 17

Intel® DCPXA250 Processor Card

7. For ARM* Multi-ICE* JTAG Use

Problem: JTAG connection fails when using ARM Multi-ICE tools.

Implication: No JTAG debugging facility is available with ARM Multi-ICE.

Workaround: Perform the following steps to fix the problem.

Note: This ECO does not affect the performance of other JTAG tools.

1. Cut the trace on the top of the processor card between U1 pin 3 and via to the right.

2. Add 30-AWG wire from the J3-3 to the via of U1 pin 1 on the bottom of the processor card.

Note: Step 3 is not required for the Rev C and Rev D DCPXA250 processor cards and ARM Multi-ICE

with their own power supply.

3. Add a 30-AWG wire from J3-2 to +3.3V.

Status: Fixed

Board Rev: Rev C and D
