Embodiment Construction

[0010] The present invention will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

[0011] A method for simultaneously programming multiple NANDFLASHs in a single task, the implementation steps are as follows: first read the image file to be programmed from the external memory, and then write the image file into the master chip; At the same time, import the data in the master chip to all NANDFLASH chips on the programming socket; in this process: use the method of simultaneously controlling the signal pins of multiple NANDFLASH chips in a single-threaded task to perform programming operations on multiple chips; In the way of error handling: every time the programming code initiates a programming operation on all chips, that is, first set the address corresponding to each NANDFLASH chip, and do not skip abnormal or absent NANDFLASH chips. As long as one piece of programming is successful, the upper layer burns The prog...

Abstract

The invention provides a method for simultaneously programming multiple NANDFLASH chips in a single task, comprising the steps of: reading data from an external memory; programming the data into a master chip; obtaining the data from the master chip during the practical programming, and simultaneously and concurrently programming the data into NANDFLASH chips on all the programming seats in the single task. In the invention, the method for simultaneously programming multiple NANDFLASH chips in the single task is adopted to replace the traditional serialized method of chip by chip programming and a multitask method of one programming task for each chip to greatly enhance the programming and producing efficiency.

Description

【Technical field】 [0001] The invention relates to a terminal product with the function of programming NANDFLASH (NANDFLASH is a storage medium), in particular to a method for simultaneously programming multiple pieces of NANDFLASH in a single task. 【Background technique】 [0002] In the production of embedded terminals, the software is generally written to the NANDFLASH before the NANDFLASH is mounted. The traditional programming method is: 1. Use the method of programming piece by piece, programming one piece at a time. 2. Concurrent programming, assigning a separate programming task to each chip. [0003] When the embedded terminal has a single function and the software scale is relatively small, the above two methods are good implementation methods, because the program image to be programmed will be relatively small at this time. But with the development, the functions of the embedded terminal become more and more complex, and the software scale becomes huge. The progra...
