Abstract
The invention discloses a method for remotely reliably upgrading XIP (execute in place) chip software. The method aims to upgrade products designed on the basis of an XIP chip and provided with a GPRS (general packet radio service) or 3G (third generation) network or a WIFI (wireless fidelity) module. When upgrading firmware of the products, the firmware can be upgraded directly remotely through the network, and upgrading failure caused by power outage or other factors during upgrading can be avoided, and reliable upgrading can be guaranteed. Meanwhile, by the method, BOOT function definition is simplified, and downloading the firmware from a server in the BOOT area is omitted. The method can remotely reliably upgrade the XIP chip, and cost for field upgrading by operators can be evidently reduced, and the problem that the firmware cannot be reset caused by power outage during upgrading is avoided.
Description
Technical field
The invention belongs to electronic information technical field, relate to a kind of method of the XIP of upgrading chip software, especially a kind of method of long-range reliable upgrading XIP chip software.
Background technology
At automotive electronics or industrial control field; For safe and reliable; Use has a large amount of XIP chips; Because the software of XIP (execute in place) chip directly moves in Flash, can't guarantee reliable read write flash upgrading in the operational process, major part need be upgraded in 4S shop maintenance process.Legacy network upgrading is through retreating to BOOT district, and download and upgrade requires equipment internal battery or device power supply (DPS) to stablize again.
Therefore, a kind of mode that can long-range reliable upgrading is continued in this area, realizes that the long-range reliable upgrading of this series products can significantly reduce the cost of operating personnel to field upgrade, and avoids because the problem that the firmware that outage causes in the escalation process can't recover.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art; A kind of method of long-range reliable upgrading XIP chip software is provided; This method can realize the long-range reliable upgrading of XIP chip and can significantly reduce the cost of operating personnel to field upgrade, avoid because the problem that the firmware that outage causes in the escalation process can't recover.
The objective of the invention is to solve through following technical scheme:
The method of this long-range reliable upgrading XIP chip software may further comprise the steps:
1) downloads redaction APP firmware through wireless network;
2) subregion marks two isolated areas that can deposit the APP firmware in external storage medium, and wherein zone 1 is used for the firmware updating of redaction, and zone 2 is used to store the firmware of current version; With redaction APP firmware stores in external storage medium;
3) backup to the APP firmware of current version in the zone 2 of external storage medium and check errorless;
4) the upgrading sign is set;
5) restart the XIP chip and get into BOOT;
6) detect the upgrading sign, if then jump to the 7th) step; Then jump to the 9th if not) step;
7) begin to detect in the external storage medium whether the APP firmware in zone 1 complete, whether version than new in the XIP chip; If firmware is complete and newly then jump to the 8th than APP firmware in the XIP chip) step; Then redirect the 9th if not) step;
8) firmware of redaction is write in the XIP chip, and detection writes success;
9) remove the upgrading sign;
Whether the APP software that 10) detects in the XIP chip is complete, if then jump to the 12nd) step;
11) the APP firmware of backup is write in the XIP chip, and detection writes success;
12) jump to the operation of APP firmware.
Above-mentioned wireless network is GPRS, 3G network or WIFI module.
Above-mentioned external storage medium is EEPROM, SPI Flash or N or Flash.
The integrality detection method of the APP firmware in the above method is: define the file layout of APP firmware, need deposit in fixing position the CRC check code of identifier, firmware length, firmware in the APP firmware, utilize the CRC check sign indicating number to guarantee that firmware is errorless.
Above-mentioned CRC check sign indicating number is with MD5 check code, SHA1 check code or self-defined reliable check code replacement.
Compared with prior art, the present invention has following beneficial effect:
The method of long-range reliable upgrading XIP chip software of the present invention is based on the remote upgrade method of disaster tolerance Flash backup, though need take the certain space of external storage medium in the equipment.But directly through the network remote upgrading, this upgrade method is simplified the BOOT functional definition, need be in the BOOT district from the downloaded firmware for it.Through to the long-range reliable upgrading of XIP chip, effectively avoided because the unit exception that outage causes in the escalation process has significantly reduced the cost of upgrade maintenance personnel to field upgrade.
Description of drawings
Fig. 1 is a FB(flow block) of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1; The method of long-range reliable upgrading XIP chip software of the present invention; Can be described as remote upgrade method based on disaster tolerance Flash backup; Be that it is to the product based on the XIP chip design, and have GPRS or 3G or network or WIFI module, need take the certain space of external storage medium in the equipment.It specifically carries out according to following steps:
1) downloads redaction APP firmware through wireless network; Said wireless network can be GPRS, 3G network or WIFI module.
2) subregion marks two isolated areas that can deposit the APP firmware in external storage medium, and wherein zone 1 is used for the firmware updating of redaction, and zone 2 is used to store the firmware of current version; With redaction APP firmware stores in external storage medium; Said external storage medium can be EEPROM, SPI Flash or Nor Flash.
3) backup to the APP firmware of current version in the zone 2 of external storage medium and check errorless;
4) the upgrading sign is set;
5) restart the XIP chip and get into BOOT;
6) detect the upgrading sign, if then jump to the 7th) step; Then jump to the 9th if not) step;
7) begin to detect in the external storage medium whether the APP firmware in zone 1 complete, whether version than new in the XIP chip; If firmware is complete and newly then jump to the 8th than APP firmware in the XIP chip) step; Then redirect the 9th if not) step;
8) firmware of redaction is write in the XIP chip, and detection writes success;
9) remove the upgrading sign;
Whether the APP software that 10) detects in the XIP chip is complete, if then jump to the 12nd) step;
