意法STM32系列芯片解密，STM32芯片破解
STM32系列32位微控制器，基于ARM? Cortex??M處理器。它能支持32位廣泛的應用，支持包括高性能、實時功能、數字信號處理，和低功耗、低電壓操作，同時擁有一個完全集成和易用的開發。
以STM32為應用的產品線非常廣泛，是由于其基于工業標準的內核、有大量的工具和軟件作支持，使該系列芯片成為眾多產品的理想選擇，不管是小終端，還是一個大型的平臺。
基于上述優勢所在，STM32系列芯片也有很多破解需求，板朗科技專業破解高難度芯片，對STM系列芯片有深入的研究，以下是關于STM32系列芯片解密介紹

STM32系統結構
系統的主要部分包括：
四個驅動單元：
- Cortex-M3 內核指令總線 (I-bus)
數據總線 (D-bus)
以及系統總線 (S-bus)
- GP-DMA(通用DMA)
三個被動單元：
- 內部 SRAM
- 內部閃存存儲器
- AHB 到 APB 橋 (AHB2APBx)該橋用來連接所有的APB 設備這些通過一個多級的AHB 總線構架相互連接
ICode 總線
該總線將 Cortex-M3 內核的指令總線與閃存存儲器指令接口相連接。指令預取操作在該總線上進行。
DCode 總線
該總線將Cortex-M3內核的DCode總線與閃存存儲器的數據接口相連接(常量加載和調試訪問)。
系統總線
該總線將 Cortex-M3 內核的系統總線（外設總線）連接到一個總線矩陣，總線矩陣協調著內核和DMA 間的訪問。
DMA 總線
該總線將DMA的AHB主機接口連接到一個總線矩陣，總線矩陣協調著CPU的DCode和DMA到SRAM、閃存和外設的訪問。
總線矩陣
此總線矩陣協調內核系統總線和DMA主控總線之間的訪問仲裁。此仲裁利用輪換算法。此總線矩陣由三個驅動部件(CPU的DCode、系統總線和DMA總線)和三個被動部件(閃存存儲器接口、SRAM和AHB2APB橋)構成。
為了允許DMA 訪問，AHB 外設通過一個總線矩陣連接到系統總線。
AHB/APB 橋 (APB)
兩個 AHB/APB 橋在AHB 和兩個APB 總線之間提供完全同步的連接。APB1 被限制在36 MHz， APB2 工作在全速狀態 (根據設備的不同可以達到72 MHz)。
存儲器結構
程序存儲器、數據存儲器、寄存器和 I/O 端口被組織到一個4G 字節的線性地址空間。
這些字節在存儲器小端格式編碼，在小端格式中，一個字中最低地址的字節為該字的最低位字節，最高地址的字節為最高位字節。
可尋址的存儲器空間被分為8 個512MB 的主塊。
所有未分配給片上存儲器或外設的存儲區域被視為是保留的。

嵌入式SRAM
STM32F10x 內置20K 字節的靜態SRAM，可以以字節、半字（16 位）、字(32 位)的方式訪問，SRAM 的起始地址為0x2000 0000。
位段
TM32F10x 里，外設寄存器和SRAM 都被映射到一個位段區里，這允許執行單一的位段的寫和讀操作。
下面的映射公式給出了別名區中的每個字是如何對應位帶區的相應位的：
bit_word_addr = bit_band_base + (byte_offset x 32) + (bit_number × 4)
其中：
− bit_word_addr 是別名存儲器區中字的地址，它映射到某個目標位。
− bit_band_base 是別名區的起始地址。
− byte_offset 是包含目標位的字節在位段里的序號
− bit_number 是目標位所在位置（0-31）
下面的例子說明如何映射別名區中SRAM 地址為0x20000300 的字節中的位2：
0x22006008 = 0x22000000 + (0x300*32) + (2*4).
對0x22006008 地址的寫操作和對SRAM 中地址0x20000300 字節的位2 執行讀-改-寫操作有著相同的效果。
讀0x22006008 地址返回SRAM 中地址0x20000300 字節的位2 的值(0x01 or 0x00)。
