Embodiment Construction

[0030] Functional Overview

[0031] As mentioned above, in the prior art, manual sintering tools are used to solidify the configurable firmware of the single board, which leads to a high error rate, and then makes the system fail during operation, affecting the normal operation of the system. Based on this, the present invention combines configurable firmware and SJTAG to realize sintering of configurable firmware content. The basic idea of ​​the present invention is: the ETC scans the specific pin of the EPLD (Electrically Programmable Logic Device) of the single board to obtain the ID number of the single board, obtains the sub-chain information to be sintered according to the single board ID, and then, according to the The corresponding connection relationship between the device pins and the configurable firmware in the sub-chain information controls the BSC in the device pins, simulates the interface timing of the configurable firmware, and realizes the sintering of the co...

Abstract

The invention provides an agglomeration method and device configurable firmware, wherein the collocating method comprises: obtaining the subchain information to be agglomerated based on a single-plate identification ID by a controller ETC, wherein the subchain information at least comprises the corresponding connection relationship between a device pin and a configurable firmware; based on the subchain information, a boundary scanning unit BSC in the ETC control device pin simulating the interface time sequence of the configurable firmware and realizing the agglomeration of the configurable firmware based on the simulated interface time sequence. The agglomeration method and device can solve the problem that the error ratio is higher due to the single-plate configurable firmware solidified using a manual agglomeration tool, furthermore the error in the action of the system is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a sintering method and device for configurable firmware. Background technique [0002] With the increase in the demand for single boards in communication equipment, the increase in the number of smart devices on the single board and their integration, and in order to cooperate with the start-up of the single board and the electronic identification of the single board, most of the single boards are equipped with I2C bus or SPI (Serial Peripheral Interface, Serial Peripheral Interface) bus non-volatile electrically erasable programmable read-only memory (Electrically Erasable Programmable Read-Only Memory, referred to as E2PROM). figure 1 It is a structural schematic block diagram of E2PROM and a controller in the related art, such as figure 1 As shown, the E2PROM is used to record the startup information of the board and the configuration information of the board, for example, t...
