For the STM32F407VGT6 chip, our first step is to carry out the FIB. After the FIB finish, we will perform the wiring reading and then complete the soft encryption and subsequent actions. The whole cycle is about one week. At present, we have successfully cracked the car detection system. For equipment and other products, customers with needs are welcome to contact us.
STM32F407VGT6 is a 32-bit high-performance ARM Cortex-M4 processor from the ST company STM32F4 series. The FLASH is 1024KB. When it executes from Flash memory at up to 168MHz, STM32F407 can provide 210 DMIPS performance and utilize ST’s ART. The accelerator implements the FLASH zero wait state. DSP instructions and floating-point units expand the range of applications. At present, the product widely uses in medical and industrial fields.
STM32F4 series chip register group: There are seven low-level registers. All instructions can access all instructions; 5-bit high-group registers are used for access by only a few 16-bit thumb 32-bit thumb2 instructions. One MSP and One PSP, MSP, is used to access the program code free service; one connection register, one program counter; the other register group also contains some unique functions, status word register, interrupt mask register, control register, and will not be detailed here. Description.
When executing an instruction, the STM32F407 series processor firstly returns the current instruction address +4 value by reading the direction to the decoding and then to the execution flow. If the instruction is interrupted, an education already in the execution stage is also complete. Still, if it is necessary to execute a branch instruction, it will clear the ARM process and re-read the direction to ensure the branch instruction’s execution.
The STM32F407VGT6 chip has 100 pins and 82 IO ports, and most of the IO ports are 5V resistant. Support for debugging SWD and JTAG. 17 timers
STM32F207IGH6 is an uncommon SGA32 series ARM chip in the BGA package. Generally speaking, the difference between the BGA package MCU and the standard QFP package is the package form, and its internal structure is the same.
For the STM32F207 crack success, our first step is to carry out FIB. After the FIB is finished, we will read the wiring and perform soft encryption and other subsequent steps. The whole cycle is about one week. At present, we have successfully cracked the car detection system. For equipment and other products, customers with needs are welcome to contact us.
