Problems solved by technology

However, for eflash, if there are preset parameter exceptions, unpreset parameters or other abnormal problems during power-on initialization, eflash may not work normally, resulting in the processor being unable to read from the eflash storage module. Get the correct program and cause the MCU to work abnormally

Abstract

The invention discloses a data processing method and device. When a storage control sub-module determines that the storage module needs to be powered on and initialized, if an analog parameter writinginstruction is received, an analog parameter is written into the storage sub-module. If a first configuration instruction is received, the storage sub-module is controlled to perform configuration according to the written analog parameter. After the system parameter is written into the storage sub-module according to the received system parameter writing instruction, and a second configuration instruction for configuring the data processing equipment is received, the system parameter is read from the storage sub-module so as to perform system configuration on the data processing equipment according to the system parameters. Thus, only when the related instruction is received, the related operation is executed, the storage module can successfully complete the power-on initialization process, the debugability of the storage module can also be improved, and therefore it is guaranteed that the data processing equipment can be normally started and then normally work.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data processing method and equipment. Background technique [0002] MCU (Microcontroller Unit, microcontroller) generally includes: flash memory (eflash), static random-access memory (Static Random-Access Memory, SRAM), and read-only memory (Read Only Memory, ROM), processor and other structures, eflash , SRAM and ROM can be used as data storage units. Wherein, the eflash may include a storage module, the startup program of the MCU may be stored in the eflash storage module, and many other application programs may also be directly executed on the eflash. [0003] Moreover, after the MCU is started, the processor in the MCU needs to normally read the program from the eflash storage module to run normally. However, for eflash, if there are preset parameter exceptions, unpreset parameters or other abnormal problems during power-on initialization, eflash may not work normally, ...
