AVR内存和intel十六进制(AVR memory and intel hex)

 我为我的大学项目工作了一个简单的AVR程序员，并且我一直在理解如何将内存从十六进制文件映射到实际的闪存。  
 例如，intel hex为我们提供了有关数据块起始地址，其中的字节数和数据本身的信息。 麻烦来自于AVR MCU，特别是ATmega16，通常有两个字节的地址：高和低。  
 起初，我写了一个简单的函数，它只是读取hex文件中的所有数据并按顺序写入，每传递两个字节就增加一个地址。 令我惊讶的是它在简单的闪烁代码上工作。 但是，我不确定，如果这种方法可行，如果有人需要复杂的内存结构。  
 所以问题是：  
 
  此解决方案是否可以用于复杂的内存结构？  
  如果没有，我怎样才能将intel十六进制地址映射到实际的flash地址？ 问题是在intel hex格式中没有高和低字节，只有地址=字节。  

I work on a simple AVR programmer for my university project, and I am stuck with understanding how I can map memory from hex file to actual flash memory.  
For instance, intel hex provides us the information about start address of data block, number of bytes in it and data itself. The trouble comes from that AVR MCUs, in particular ATmega16, often have one address for two bytes: high and low.  
At first, I wrote a straightforward function, that just reads all the data from hex file and write it sequentially, increasing address by one each two bytes passed. To my surprise it works on simple blinky code. However, I am not sure, if this approach would work, if someone needs complex memory structure. 
So the questions are: 
 
 Will this solution work on complex memory structures? 
 If not, how can I map intel hex address into actual flash address? The problem is there is no high and low bytes in intel hex format, only address = byte.

 withReader块隐式返回闭包的最后一行，在您的情况下是：  
        println "YamlTapeLoader : inside readFrom : "+reader
 
 并且println返回null ，因此将代码更改为：  
    def tape = file.withReader(FILE_CHARSET) { reader ->
        def ret = YamlTape.readFrom(reader)
        println "YamlTapeLoader : inside readFrom : "+reader
        ret // Return the result of YamlTape.readFrom
    }
 
 它应该工作

 您的readFrom方法具有相同的错误...将其更改为：  
static YamlTape readFrom(Reader reader) {
  try {
    println "YamlTape : inside readFrom reader.size() = "+reader+" YamlTape: "+YamlTape

    def ret = Yaml.loadAs(reader, YamlTape)
    println "YamlTape : after readfrom"

    ret // Return the YamlTape
  } catch (YAMLException e) {
    println "YamlTape : inside catch block"
    throw new TapeLoadException('Invalid tape', e)
  }
}

The withReader block implicitly returns the last line of the closure, which in your case is: 
        println "YamlTapeLoader : inside readFrom : "+reader
 
And println returns null, so change the code to: 
    def tape = file.withReader(FILE_CHARSET) { reader ->
        def ret = YamlTape.readFrom(reader)
        println "YamlTapeLoader : inside readFrom : "+reader
        ret // Return the result of YamlTape.readFrom
    }
 
And it should work 
Edit 
Your readFrom method has the same error... Change it to: 
static YamlTape readFrom(Reader reader) {
  try {
    println "YamlTape : inside readFrom reader.size() = "+reader+" YamlTape: "+YamlTape

    def ret = Yaml.loadAs(reader, YamlTape)
    println "YamlTape : after readfrom"

    ret // Return the YamlTape
  } catch (YAMLException e) {
    println "YamlTape : inside catch block"
    throw new TapeLoadException('Invalid tape', e)
  }
}
