Troubleshooting Guide
Table 3-1. Troubleshooting Guide
Problem
Reason
The SRAM is not connected.
Solution
Verify all solderings, and
make sure the Pin1 on the
SRAM matches the one on
the footprint. Make sure the
SRAM pinout is correct.
SRAM does not work
properly.
SRAMEN is not mounted.
XRAM interface is not
enabled in the AVR device.
Some of the ADDRESS
HIGH BYTE jumpers may be
set incorrectly.
Make sure that the SRAMEN
is connected to GND on the
AUX connector.
Verify that the code actually
enables the XRAM interface.
Connect some or all of
ADDRESS HIGH BYTE
jumpers.
AVR ? STK501 User Guide
SRAM does not work when
used by devices on the
STK500 board.
After doing a High-voltage
Programming of the AVR, the
SRAM does not work
properly.
WR, RD and ALE signals
must be strapped using two
2-wire cables.
The SRAM might be
damaged due to the High-
voltage needed to program
the AVR.
Use two 2-wire cables, and
connect these signals to the
appropriate pins.
Make sure the SRAM
handles 5V, if High-voltage
Programming mode should
be used.
