我所做的一切

我已经开始了我的第一个逆向工程项目，并从Delonghi Dedica EC 685咖啡机的PIC 16 F1938处理器中提取了HEX。股票固件可以在这里找到：Delonghi Dedica EC685 Stock Firmware
我已经使用MPLabX对模拟器内存进行了编程，然后使用“输出到文件”来保存DisAssy输出。这给了我整个程序的内存和一些小的注册表名称修复，我‘希望‘这将是一个有效的汇编文件。PIC16F1938 Assembly File

问题

当我在MPLab X IDE下使用pic-as来编译它时，我得到一个错误，看起来好像是说没有足够的程序空间！？这是错误的，因为代码是从我们正在编程的设备中提取的。
主要错误似乎是error: (1347) can't find 0x2943 words (0x2943 withtotal) for psect "code" in class "CODE" (largest unused contiguous range 0x800)，我无法理解。

帮助是非常感谢，因为我是新的PIC大会，但我是一个经验丰富的软件工程师分支：）

在从git仓库中创建了一个十六进制文件的PIC反汇编后，我将源文件（newpic_8b_asm_func.S）here。
