If the firmware becomes corrupted or requires
manual reinstallation for any reason, follow these steps to restore the firmware.
This is demonstrated in the TMAG5170 EVM Quick Start Video:
- Configure the MCU on the TI-SCB
Controller to Device Firmware Update (DFU) Mode.
- The MCU entering DFU mode
is possible. If so, then the GUI sends a notification and tries to
update the firmware to the latest version after the GUI is connected to
the PC.
- DFU mode can be entered
manually through one of the following methods while the TI-SCB
Controller is powered on:
- Through software:
- Send the
command 'bsl' on the TI-SCB's USB Serial (COM)
port.
- Though the
hardware:
- Make sure
TI-SCB is connected to the PC through a USB
- Short the
two test points near PK1 and PK2 of the header pins (see
Figure 3-7) with a pair of tweezers (or wire)
while pressing the RESET button.
- LEDs D1 and D2 are off if
successful.
- With the MCU in DFU mode, upload
the firmware through the GUI:
- Open the File menu
and select Program Device.
- The firmware update
initiates.
- After the GUI
re-initializes, the TI-SCB automatically connects.
If the firmware programming was unsuccessful, then TI recommends to repeat the above
steps with a different USB port connection on the machine.
