Abstract
The utility model relates to an ARM embedded terminal remote upgrading device based on a GPRS network. The device consists of a main control chip ARM, a GPRS Modem and an RS-232 bus which is used for connecting two modules. A Flash memory arranged in the ARM is divided into a boot sector which stores codes of system initialization and starting, a user code jumping region which stores instructions that are jumped into a corresponding user code region, a user code 1 region which stores the user codes executed by a current ARM embedded type terminal and a user code 2 region which stores remote upgrading data received by the GPRS Modem stored by an IPA. The format of an upgrading data block received by the GPRS Modem is divided into an ID area of the upgrading data block, a data area of the upgrading data block and an inspection area of the upgrading data block. The device utilizes the Flash resources of the ARM, manual field upgrading treatment is not needed, etc., thus realizing remote software updating on the ARM embedded type terminal, reducing system cost and the complexity of engineering. The device of the utility model has the function of transmission resuming at break-points, which shortens upgrading time.
Description
Technical field
The utility model relates to the update device of built-in terminal, relates in particular to a kind of ARM built-in terminal remote upgrade device based on GPRS network.
Background technology
Domestic embedded system has been widely used in fields such as industry, communication, information household appliances, and has been penetrated into other industry.Along with new technology continue to bring out and to the improving constantly of systemic-function, performance requirement, the user must be at the variation upgrade-system of client's demand, to prolong the life cycle of system, the application of enhanced system is improved systematic function.Traditional embedded system upgrading mode normally attendant arrives device context, unpacks to rewrite or change Flash, and is huge and when being distributed in different places when number of devices, will cause problems such as the upgrade maintenance process is loaded down with trivial details, cost is high, the time is long.And adopting the systems soft ware remote online upgrading of distributed monitoring system on-site terminal to exist update time longer, escalation process takes place to interrupt causing upgrading successfully not wait defective.If can construct a kind of device effectively, by the relevant ROMPaq code of GPRS network transmission, realize remote radio upgrade, can effectively address the above problem.
Summary of the invention
The purpose of this utility model is that the system that utilizes ARM realizes ARM built-in terminal remote radio upgrade at application programming (hereinafter to be referred as IAP) and inner Flash memory thereof by GPRS network transmission ARM ROMPaq code.
For reaching the purpose of this utility model, the technical scheme of employing is: device includes main control chip ARM and GPRS Modem functional module, and connects two RS-232 buses between the functional module; Flash memory with main control chip ARM inside is divided into promoter region, personal code work redirect district, four parts in personal code work 1 district and personal code work 2 districts simultaneously, and the form of the upgrade data piece that GPRS Modem is received is divided into the data field of upgrade data piece ID district, upgrade data piece, the check field of upgrade data piece.
The code of system initialization and startup is deposited in promoter region described in the utility model.
The instruction that jumps to the relative users code area is deposited in personal code work redirect described in the utility model district.
In personal code work described in the utility model 1 district and personal code work 2 districts, personal code work 1 district is used for depositing the personal code work that current ARM built-in terminal is being carried out, and personal code work 2 districts are used for depositing by IAP deposits the remote upgrade data that GPRS Modem receives.After upgrade data finishes receiving, revise the instruction in personal code work redirect district by IAP, make the new upgrade code of ARM built-in terminal operation.Upgrade data is carried out the piecemeal transmission, and each little blocks of data is numbered, main control chip ARM preserves the numbering that last piece receives successful upgrade data, realizes the breakpoint transmission function.
Adopt the beneficial effect of technical solution of the present invention to be: to pass through GPRS network, realized remote software upgrade to the ARM built-in terminal, make full use of the Flash resource of main control chip ARM own, without external RAM or eeprom chip, need not artificial field upgrade, reduce the complexity of system cost and engineering, reduced expending of field upgrade.Shorten update time by the breakpoint transmission function, avoid interrupting causing not success of upgrading because of upgrading.
