Recently, the company's products need to increase the remote upgrade function, the boot loader program is written and handed to the production department when they feedback each product process needs to brush write two times (a boot loader an app), production progress slowed waste time, so study how to two programs and for one.Reference: http://blog.csdn.net/yx_l128125/article/details/13591743 After the successful implementation of the two programs merged into one.How to combine IAP +appThere ar

The bad thing is this base64 strings are stored in a variable and there ' a limitations for it ' s size. But for a small strings it wokrs.

What is Intel HEX format?
An Intel HEX file is an ASCII text file that records text lines. In an Intel
Conversion between JAVA Hex and string, and java hexToHexStringPublic static String toHexString (int I) returns the String representation of an integer parameter in the hexadecimal notation.If the parameter is negative, the unsigned integer is 232. Otherwise, the value is equal to the parameter. Convert the value to an ASCII numeric string without leading 0 in hexadecimal notation (base 16. If the value of the unsigned number is zero, it is expressed

For the embedded, the hex file may be familiar to everyone, yes, we study in the University of the 51 single-chip computer code compiled on the Keil generated after the hex file. What does that bin file mean, and what's the difference between it and the hex file? This is not the focus of this article, the following simple description:Most commonly speaking,

Note:A previous article translated during format conversion. At that time, I didn't know much about these things, so it was not good at translation. I have not been exposed to this information for about 3 or 4 years, so even if there is an error, it cannot be corrected now. I hope I will not be laughed at when I figure out my computer. Thank you for your criticism.
