Reverse Engineer STM32F050K4 Microprocessor Protection over flash memory, and break stm32f050k4 secured mcu firmware file, extract source code from stm32f050k4 microprocessor flash memory;
The device has the following features:
- 4 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states and featuring embedded parity checking with exception generation for fail-critical applications by restoring microcomputer stm32f072cb firmware file.
- The non-volatile memory is divided into two arrays:
- 16 to 32 Kbytes of embedded Flash memory for programs and data
- Option bytes
- The non-volatile memory is divided into two arrays:
The option bytes are used to write-protect the memory (with 4 KB granularity) and/or readout-protect the whole memory with the following options:
- Level 0: no readout protection
- Level 1: memory readout protection, the Flash memory cannot be read from or written to if either debug features are connected or boot in RAM is selected
Level 2: chip readout protection, debug features (Cortex-M0 serial wire) and boot in RAM selection disabled.
At startup, the boot pin and boot selector option bit are used to select one of three boot options:
- Boot from User Flash
- Boot from System Memory
- Boot from embedded SRAM
The boot loader is located in System Memory. It is used to reprogram the Flash memory by using USART1.
