Abstract
A method for adaptively identifying flash memory type includes driving a flash memory interface according to a predetermined configuration and a predetermined protocol of the flash memory interface to send a reading command to a flash memory module to obtain a flash memory identity by successfully reading the flash memory module; changing at least one of the configuration and the interface protocol of the flash memory interface then performing the obtaining the flash memory identity again until all preset adjustments have been tried; and storing the obtained flash memory identity and a firmware corresponding to the obtained flash memory identity to a designated address of a non-volatile memory when the flash memory module is successful read. The above automated method can solve the disadvantages of high cost and low manufacturing flexibility caused by conventional manual identification and re-burning of eFuses.
