Welcome to the Hardware quest! There are three levels of difficulty in it, but foe all of the tasks the main idea is to fine a password that unlocks the board. To do it, you need to dump the firmware from the board and than reverse engineer it.
## Dump firmware ## Dump firmware
You can use `OpenOCD` to dump firmware from STM32F103 mcu: You can use `OpenOCD` to dump the firmware from STM32F103 mcu:
