Description
Technical field
The present invention relates to a kind of safe DSP firmware on line upgrading methods, the anti-DSP burnt to death of more particularly to a kind of equipment consolidates
Part online upgrading method.
Background technology
Usual DSP firmware can be with programming in FLASH.Before product export, firmware can be burnt by following two method
Write on FLASH：
1st, using programmable device firmware programming in FLASH, FLASH is then welded to circuit board；
2nd, using emulator DSP firmware programmings in FLASH.
But after product export, when needing firmware updating, because condition limits, above-mentioned two kinds of programming firmware methods
It can not all use, only can be used in line writing method.
Realize DSP in line writing, it is necessary to which DSP firmwares are in addition to comprising the module of product function is realized, it is also necessary to
Include the module for realizing firmware programming.The specific method of the online firmware programmings of DSP is：
1st, start DSP, perform programming to FLASH firmware on line upgrading program；
2nd, DSP is made to perform firmware programming module；
3rd, new firmware is copied to memory headroom by firmware programming module by external bus (network, USB, serial ports etc.)；
4th, the firmware programming of memory headroom to FLASH.
But this method have one it is fatal the defects of：(powered off when firmware programming exception during firmware error or programming),
DSP firmwares may not be activated again, can not naturally also perform firmware programming module again, and the equipment " change brick " being commonly called as.
That is, DSP normal startup and realizing that online firmware programming all relies on previous firmware programming success.
Accordingly, it is desirable to provide a kind of safe DSP firmware on line upgrading methods, when failing in line writing firmware, are remained to
It is normally carried out firmware on line upgrading next time.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art and deficiency, there is provided a kind of anti-DSP firmwares burnt to death of equipment
Online upgrading method, realize when remaining to be normally carried out firmware on line upgrading next time when line writing firmware fails.
The purpose of the present invention is realized by following technical scheme：
A kind of anti-DSP firmware on line upgrading methods burnt to death of equipment, two subregions are marked off in FLASH：One is applied journey
Sequence subregion and a safe programming firmware partition；Application partition, which is used to install, realizes that the DSP application programs of product function are consolidated
Part；Safe programming firmware partition is used to install safe programming firmware, and safe programming firmware is used to realize online upgrading DSP application journeys
Sequence firmware；The programming before dispatching from the factory of the firmware of safe programming firmware partition is good, in subsequent use or during upgrading, the subregion it is interior
It can't permit change.
Preferably, DSP has two kinds of mode of operations：Normal mode of operation and safe programming pattern.
Specifically, DSP determines which kind of mode of operation entered in powerup/reset, according to hardware setting：When the normal work of entrance
During operation mode, application firmware can be started in application partition, realize product function；When entering safe programming pattern,
Safe programming firmware can be started in safe programming firmware partition, realize the upgrading of application firmware.
Preferably, dsp chip needs to select GPIO pin for detecting user's mode of operation to be set.
Preferably, for the dsp chip of part, it can determine that DSP refers in FLASH according to specific GPIO level state
Address location startup is determined, it is possible thereby to determine the initial address of application partition and safe programming subregion.
Specifically, above method workflow is specific as follows：
(1) DSP is after powerup/reset, and according to specified GPIO incoming level state, decision enters (2) step, or enters
Perform application program；
(2) start safe programming program in safe programming subregion, perform specific initialization operation：Initialization system clock,
Memory chip and the peripheral hardware related to programming firmware；
(3) new DSP application firmwares are copied to internal memory by external bus or pluggable holder；
(4) FLASH application partition is wiped；
(5) the application firmware programming in internal memory to application partition.
Preferably, for the dsp chip that can only start in FLASH default address, the acquiescence of the FLASH can be started ground
Location is arranged to the initial address of safe programming firmware partition；DSP starts, so in powerup/reset in safe programming firmware partition
The GPIO incoming level states for determining mode of operation are read afterwards, determine to turn to jump to application partition execution application program, still
Safe programming firmware program is continued executing with this subregion.
Specifically, above method workflow is specific as follows：
(1) DSP, into safe programming subregion, is performed after powerup/reset and is started code, performs specific initialization behaviour
Make：Initialize system clock, memory chip and the peripheral hardware related to programming firmware；
(2) according to the incoming level state for specifying GPIO, decision enters (3) step, or enters and perform application program；
(3) safe programming program is started；
(4) new DSP application firmwares are copied to internal memory by external bus or pluggable holder；
(5) FLASH application partition is wiped；
(6) the application firmware programming in internal memory to application partition.
The present invention compared with prior art, has the following advantages that and beneficial effect：
The present invention performs firmware upgrade behaviour using the DSP firmware mounting means of the double subregions of FLASH by safe programming firmware
Make, avoid because firmware updating is abnormal and the problem of cause DSP firmwares to start can not to carry out with follow-up firmware programming.
Brief description of the drawings
Fig. 1 is the program initialization broad flow diagram of method 1 in embodiment.
Fig. 2 is the program initialization broad flow diagram of method 2 in embodiment.
Embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are unlimited
