• BSL command format:
bsl
– This command puts the device in BSL mode, which is necessary before reflashing the SCB firmware. An
alternative to entering BSL mode is to do it in hardware as described in step 1b of
. Before
BSL is entered, LED D1 is ON. If BSL mode is successfully entered, LED D1 is turned OFF so that only
the Power LED (LED D5) is on. After entering BSL mode, the device does not accept any of the above
commands.

5.2 Evaluation Without SCB and GUI (EVM Stand-Alone Mode)
The TMAG5328EVM can operate in a stand-alone mode that does not require the SCB or GUI. To operate in
stand-alone mode, an external power supply must be connected to the TMAG5328EVM (see
When in standby mode, B
OP
can be set using either the DAC, potentiometer, or fixed resistor options.
Remember that the DAC output voltage cannot be changed without the SCB. The DAC output voltage will
only be set to the value that was previously stored in its nonvolatile memory by the GUI. As a result, the DAC
cannot be swept to find the sensed magnetic flux density of the TMAG5328 unless the SCB is connected. The
potentiometer, however, does not require the SCB to estimate the sensed magnetic flux density TMAG5328 (see
).
When in stand-alone mode, the TMAG5328 OUT pin can be probed at the test point that is labeled "OUT" on the
board or on pin 9 of header J1. In addition, LED D1 can be used to visually observe the state of the TMAG5328
