Intel®DCPXA210 Processor Card

4. Remove Coin Cell Battery

Problem: Specification change to BATT_VCC. Discontinue to use the backup battery and connect

BATT_VCC to VCCQ.

Implication: VCCQ could attempt to charge battery if BATT_VCC is lower than VCCQ.

Workaround: Follow the steps below to fix the problem:

1. Remove the 0-ohm resistors R29B and R38B and battery holder B1.

2. Add 30-AWG wire from TP11 (red) to TP22 (red) .

Status: No Fix

Board Rev: Rev A

5. Incorrect Boot Mode Selected For PXA210 Processor

Problem: The DCPXA210 processor card is configured to boot the PXA210 processor in 32-bit mode.

Implication: PXA210 does not function correctly. It only supports a 16-bit data bus.

Workaround: Follow the steps below to change the boot mode:

1. Remove the 0-ohm resistor, R65B.

2. Add 30-AWG wire from R65B pad attached t o ball F14 to +3.3 V.

Status: No Fix

Board Rev: Rev A
