IDA Pro插件LoadProcConfig

## Overview **LoadProcConfig** is an IDA Plugin to load processor configuration files. With just a couple of clicks configuration files can turn this:  Into this, adding memory regions, entries and registers/ports:  By default IDA is shipped with configuration files for many processors in **IDA/cfg** folder. These configuration files are loaded automatically when corresponding processor module is loaded. However, this approach has some disadvantages: 1. You have to keep your own configuration files inside IDA 2. There is no easy way to load and apply configuration file on existing database 3. Most important, ARM processor module doesn't have configuration file Current plugin was implemented to address all these issues. ## Installation Just copy **LoadProcConfig.pmc** and **LoadProcConfig.pmc64** to IDA plugins folder. ## Usage From **Edit / Plugins** menu choose **Load Processor Config**. Then open configuration file using the file dialog. IDA will parse this file and display all available devices. Pick your device and press **OK**.  Choose what do you want to load from this configuration file.  Plugin will reanalyse entire database using device description and create additional memory regions. ## Configuration files There are many configuration files in **IDA/cfg** folder. While the format has no proper documentation, we can get some ideas by looking into **idasdk/module/iocommon.cpp** Every configuration includes following parts: ``` ; Default device in current configuration file .default MYDEVICE ; Device description .MYDEVICE ; RAM/FLASH specification RAM=512 ROM=8192 EEPROM=512 ; Memory Map area DATA I_SRAM 0x00060:0x00260 Internal SRAM area DATA E_SRAM 0x00260:0x10000 External SRAM ; Interrupts and reset vector assignments entry RESET 0x0000 External Reset, Power-on Reset and Watchdog Reset entry UART_RX 0x0009 UART, Rx Complete ; Registers (with bit fields) USR 0x000B UART Status Register USR.RXC 7 UART Receive Complete USR.TXC 6 UART Transmit Complete USR.UDRE 5 UART Data Register Empty USR.FE 4 Framing Error USR.OR 3 Overrun ``` You can find example for STM32F40x in **Configurations** folder
