无论是生成二进制固件的机器还是使用此二进制固件会闪光的设备,它们的字节存储顺序都需要小心对待。
One thing to be very careful here is the endianness of either the machine that produces the binary firmware and the device that will be flashed using this binary firmware.
Endianness是指多字节字在内存中的存储顺序。
Endianness refers to the order in which the bytes of a multi-byte word are stored in memory.
如果可以选择的话,请使用标准库函数来进行字节交换操作,并按照字节在数据文件中存储的顺序进行标准化;网络字节顺序最适合这种工作。
If you have the option, use standard library functions to do byte-swapping operations, and standardize on the order in which bytes are stored in your data files; network byte order is the best.
CHAR存储固定长度的单字节或多字节的文本字符串(最高可达32,767个字节);在整理文本数据时支持使用代码集顺序。
CHAR Stores single-byte or multibyte text strings of fixed length (up to 32,767 bytes); supports code-set order in collation of text data.
VARCHAR存储可变长度的单字节或多字节文本字符串(最高可达255个字节);在整理文本数据时支持使用代码集顺序。
VARCHAR Stores single-byte or multibyte text strings of varying length (up to 255 bytes); supports code-set order collation of text data.
存储器存取的字节顺序(Big -Endian或Little - Endian)是由操作系统指定的。
The byte ordering (Big-Endian or Little-Endian) for a storage access is specified by the operating system.
第一个阶段是将字符序列从字节顺序(字符在内存中如何存储)转换成正确的手写顺序(字符如何在纸面上显示)。
The first phase translates the sequence of characters from byte order (how the characters are stored in memory) to the proper written order (as it would appear on paper).
big -endian意味着最高位字节存储在最低地址(按高位优先的顺序存储字)。
Big-endian means that the most significant byte has the lowest address (the word is stored big-end-first).
而little -endian意味着最低位字节存储在最低地址(按低位优先的顺序存储字)。
Little-endian means that the least significant byte has the lowest address (the word is stored little-end-first).
文件是一些具有永久存储及特定顺序的字节组成的一个有序的、具有名称的集合。
A file is an ordered and named collection of a particular sequence of bytes having persistent storage.
文件是一些具有永久存储及特定顺序的字节组成的一个有序的、具有名称的集合。
A file is an ordered and named collection of a particular sequence of bytes having persistent storage.
