Follow these steps to install the
firmware.
- Configure the MCU on the SCB to
be in Device Firmware Update (DFU) Mode. DFU mode can be entered manually
through one of the following methods while the SCB is powered on:
- Through software:
- Send the command
"bsl" on the SCB's USB Serial (COM) port.
- Though hardware (with the
EVM removed):
- Short the two
test points labeled DFU (see Figure 4-3) with a pair of tweezers (or wire) while pressing the RESET
button. If this is done correctly, then LED D1 on the SCB turns
off while the LED D5 (the power LED) remains on. If LED D1 is
still on, then the GUI firmware is still active and the device
has not entered DFU mode.
- With the MCU in DFU mode, the
firmware can now be uploaded through the USB Bootstrap Loader (BSL) scripter
tool and batch file by doing the following:
- Download the firmware
package and BSL scripter tool from the EVM page, or use the link: https://www.ti.com/tool/download/sbac295.
- Unzip the firmware folder
and run the .bat file.
- Unplug the USB cable from
the PC after the firmware is flashed, then plug the cable back in to
reset the SCB.
