Firmware update method and firmware update device
TLDR
In this article, the authors propose a firmware update method for embedded Linux, which uses a client for loading firmware and writing the firmware into a second memory space so as to update the firmware in a nonvolatile random access storage device; the address space is an address space which enables the firmware to be mapped into an internal memory through a user program.Abstract:
The invention provides a firmware update method and a firmware update device, relates to the field of embedded Linux, and aims at solving the problem that firmware existing in the prior art is quite difficult to update. The firmware update method includes that a client is used for loading firmware and writing the firmware into a second memory space so as to update the firmware in a nonvolatile random access storage device; and the second memory space is an address space which enables the address space, in the nonvolatile random access storage device, of the firmware to be mapped into an internal memory through a user program. Due to the facts that the address space, in the nonvolatile random access storage device, of the firmware is mapped into the internal memory through the user program, and then the internal memory is updated through the user program, the updating difficulty of the firmware is enabled to be low.read more
