趁熱打鐵，在上一PIC32MZ UDP ethernet bootloader的基礎(chǔ)上我又完成了采用TCP協(xié)議的PIC32MZ ethernet bootloader。兩款ethernet bootloader基本架構(gòu)都一樣，數(shù)據(jù)包格式也一樣。TCP ethernet bootloader 也分兩部分，我將他們命名為PhnLoader_v4.0和PhnBoot_v4.0。

PhnLoader_v4.0

　　PhnLoader_v4.0 是PC端host 程序。

運(yùn)行環(huán)境：Window + .NET Framework 4.5

開(kāi)發(fā)語(yǔ)言：C#

通信類(lèi)型：TCP Server

IP 地址： 192.168.1.105

端口號(hào)： 8720

　　UI 如下：

　　主要代碼如下：

try{while(loaderReader.Peek()>=0){pBarLoading.PerformStep();recordLine=loaderReader.ReadLine();if(recordLine.Contains(EXTEND_TOKEN)==true){if(recordLine.Contains(USER_ID_TOKEN)==true){isNextLineUserID=true;continue;}//elseif(recordLine.Contains(CONFIG_BITS_TOKEN)==true)//{//constintADDR_U_START_INDEX=9;//constintADDR_U_LENGTH=4;//stringaddrU=recordLine.Substring(ADDR_U_START_INDEX,ADDR_U_LENGTH);//loaderUpperAddr=Convert.ToInt32(addrU,16)<<16;//isNextLineConfigBits=true;//continue;//}elseif(recordLine.Contains(PIC32_CONFIG_BITS_TOKEN)==true){constintADDR_U_START_INDEX=9;constintADDR_U_LENGTH=4;stringaddrU=recordLine.Substring(ADDR_U_START_INDEX,ADDR_U_LENGTH);loaderUpperAddr=Convert.ToInt32(addrU,16)<<16;isNextLineConfigBits=true;continue;}else{constintADDR_U_START_INDEX=9;constintADDR_U_LENGTH=4;stringaddrU=recordLine.Substring(ADDR_U_START_INDEX,ADDR_U_LENGTH);loaderUpperAddr=Convert.ToInt32(addrU,16)<<16;continue;}}elseif(recordLine.Contains(END_OF_HEX_FILE_TOKEN)==true){break;}if(isNextLineUserID){isNextLineUserID=false;//donothing;}elseif(isNextLineConfigBits){if(!DownloadConfigLine(recordLine)){Debug.WriteLine("Errorfoundduringconfigurationbitsprogramming");loaderReader.Close();loaderServer.Close();btnDownload.Enabled=true;return;}isNextLineConfigBits=false;}else{if(!DownloadDataLine(recordLine)){Debug.WriteLine("Errorfoundduringdataprogramming");loaderReader.Close();loaderServer.Close();btnDownload.Enabled=true;return;}}}}catch(Exceptionex){Debug.WriteLine("Error:"+ex.Message);textBoxStatus.ForeColor=Color.Red;textBoxStatus.AppendText("Downloadingfailedrn");textBoxStatus.ForeColor=Color.Black;loaderServer.Close();loaderReader.Close();btnDownload.Enabled=true;return;}textBoxStatus.AppendText("Downloadingcompletedrn");
