Enter @@@ (TinySafeBoot’s start-up password) in the text field to the left of the Send button, and click Send. The bootloader should start with TSB and mainly contain information about the firmware version and AVR settings. TSB is just an identifier used by TinySafeBoot, most likely its initials. The output should match that in Figure 8-12.

Setting a Custom Password

Now we need to set a custom password so that we can monitor the power levels when a password is entered.

First, close the serial terminal. Then enter the following lines in the Python console window, which is at the bottom center of the ChipWhisperer main window.

>>> self.target.driver.ser.write("@@@")

>>> self.target.driver.ser.read(255)

We use the serial command self.target.driver.ser.write("@@@") to send the current password for the bootloader. Next, we enter the serial command self.target.driver.ser.read(255) to read up to the next 255 bytes from the bootloader to see its response to our sending the password (see Figure 8-13).
