Sigh for China's set-top box industry!

Today to help an uncle to Skyworth HC2600 set-top box upgrade, even skyworth his own explanation are said not clear not Chu. Maybe I'm a little white! The serial port parameter did not say, CTRL + C in which interface Press, command which interface to lose, too much is said not clear. Just into the set-top box industry I do not understand, there is all the solution is not any document, any set-top box chip does not have any data manual, HiSilicon, LAN, Haier, for me such a small white, these materials can only say too little too little. There is no uniform standard for set-top box upgrades.

Sigh: There are too many do not understand, these days are worried dead, Wang teacher painted set-top box board, take to test, I and Guo Chengshi brother first Discussion set-top box system, the system from where, flash,flash how to burn, serial, no download tools, now from the uncle that know is to you the download tool, you will not complete. System write in Flash which paragraph! The boot program is sent in Flash which segment. It's better to learn from the beginning.

1. The data structure and algorithm of C language

Sigh for China's set-top box industry!
