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 +3.3 V.

Status:

Fixed

Board Rev:

Rev C and D
