4.2.1.2.1 Firmware Debug
If the firmware gets corrupted or must be manually reinstalled for any reason, follow these steps to
reinstall the firmware.
1. Configure the MCU on the PAMB Controller to be in Device Firmware Update (DFU) Mode.
a. It is possible that the MCU has already entered DFU mode. If so, the GUI will notify you and try to
update the firmware to the latest version after the GUI is connected to the PC.
b. DFU mode can be entered manually through one of the following methods while the PAMB
Controller is powered on:
• Through software:
– Send the command 'bsl' on the PAMB's USB Serial (COM) port.
• Though hardware (with the EVM removed):
– Short the two test points near PK1 and PK2 of the header pins (shown in Figure 2 ) with a
pair of tweezers (or wire) while pressing the RESET button.

2. With the MCU in DFU mode, the firmware can now be uploaded through one of the following methods:
• Through the GUI:
– Plug in the PAMB Controller to a PC via the USB port and launch the GUI. DFU mode should
be automatically detected, and the firmware will be uploaded automatically.
• Through the USB Bootstrap Loader (BSL) scripter tool and batch file:
– Download the firmware package and BSL scripter tool from the EVM page, or use the following
