Synopsis
This failure relates to a non-critical memory failure for
radios equipped with an expansion board containing a
soldered eMMC part.
All necessary testpoints are located under the
Expansion board shields and VOCON board shields.
The memory signal lines are only traceable at series
zero-ohm jumpers, and is not accessible when the radio
is functionally assembled.
A special test fixture is required to access the signals,
along with short wires soldered at the desired testing
points. Signal integrity is affected by passive probes
and long test wires. Testing scripts for eMMC functional
operation are only possible with a special software build
which enables these test script commands.
Measure voltage
on R2313 on
Expansion board
and verify 1.85v
Measure voltage
on R2312 on
Expansion board
and verify 2.775v
Measure voltage on
R2465 on Expansion
board and verify
AVR_STATUS_3.3v
Voltage
present on
output of U2410

Measure clock at TP6301
on VOCON and verify
F2_TIMER_OUT. See
