MSP430FG4618/F2013 Experimenter Board (MSP
‑
EXP430FG4618)
5.
The MSP430FG4618 is no longer accessible through JTAG, is something wrong with the
device?
•
Verify that the target device is powered properly
•
If the target is powered locally, verify Vcc is applied to pin 4 of the JTAG header
•
If communication and power are correctly applied to the target and the issue persists, it may be
due to the MSP430FG4618 accidentally being programmed with MSP430F2xx source code. In
some conditions ‘F2xx source code loaded onto the FG4618 can configure the SVS module to
monitor SVSIN (P6.7) and reset the device in case of a low voltage condition externally applied.
Temporarily connecting P6.7 of the FG4618 to Vcc and reprogramming the target device with the
valid source code will eliminate this issue.
6.
Does the experimenter board protect against blowing the JTAG fuse of the target devices?
No. Fuse blow capability is inherent to all Flash-based MSP430 devices in order to protect user’s
intellectual property. Care must be taken to avoid the enabling of the fuse blow option during
programming that would prevent further access to the MSP430 device(s) through JTAG.
7.
I am measuring system current in the range of 30mA, is this normal?
Current consumption of the system is dependent on the functions and operation of the hardware being
performed. The RF connectivity and isolated UART communication support, when used, can reach
these current consumption levels. Take care that these elements are not accidentally enabled,
specifically the isolated UART, if such system currents are not expected.
8.
Can I use two FETs to perform simultaneous access of the FG4618 and F2013 during
program/debug?
Yes, independent flash emulation tools (either USB or Parallel for FG4618 and USB only for F2013)
can be simultaneously used to program the MSP430 target devices. When supplying power from the
FET, it is recommended to use only one FET to source power. The second FET can sense this voltage
level instead of supplying power, to avoid any voltage conflicts in-system. See
Section 5
for details
regarding supported power supply configurations.
9.
I cannot properly open the workspace and projects provided in the .zip file with IAR, how can I
open the sample code?
The IAR workspace/projects included for the sample code provided has been created using IAR
Embedded Workbench Version 3.42A. These projects are not backward compatible with older IAR
releases and will not open using prior versions. New workspace/projects can be created and the
sample code source files can be added manually in order to build these samples with older versions.
Instruction for setting up a project in IAR are described in the
IAR Embedded Workbench IDE Version
7+ for MSP430 MCUs
.
10.
I have loaded the FG4618 and F2013 sample code for the capacitive touch sensing application.
It doesn’t seem to be working. What is wrong?
Verify that the correct jumper settings are used for H1 enabling the I
2
C communication link between
MSP430s. Make sure jumper JP2 is removed, disconnecting LED3 from the touchpad circuitry. When
connected, the LED causes the measurement of the capacitive touch element on P1.0 to fail.
