Embodiment Construction

[0025] Functional Overview

[0026] In consideration of the problem that the crash that occurs when downloading in the USB mode or the UART mode in the related art cannot be self-repaired, the embodiment of the present invention provides a signal transmission scheme. In this scheme, a piece of equipment with a protocol conversion module and a personal computer ( The download board (that is, the signal transmission device) of the controllable function of the Personal Computer (abbreviated as PC) side, the software sends the data packet, and judges the state of the terminal according to whether the reply data packet is received, and the software is controlled by the download board on the download board. The module automatically opens the USB or UART channel, or completes the conversion of the USB or UART signal to the JTAG protocol, and automatically selects the protocol for downloading, which solves the problem of crashing during the terminal upgrade process and greatly improve...

Abstract

The present invention discloses an apparatus and a method for signal transmission. The apparatus is used to transmit a signal for upgrading and / or repairing a terminal, is applicable to a communication system which comprises software and the terminal, and comprises: a downloading panel control module, configured to transmit a data packet from the software to the terminal, and to transmit the signal from the software according to whether a response data packet corresponding to the data packet is received from the terminal; and a protocol conversion module, configured to receive the signal from the downloading panel control module, to convert the signal into a joint test action group (JTAG) signal, and to transmit the converted JTAG signal to the terminal. The present invention improves the efficiency of version upgrading.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signal transmission device and method. Background technique [0002] At present, with the increase in the number of global digital mobile users, the user's demand for terminals is also increasing rapidly. Therefore, the competition in the terminal market is also becoming more and more fierce. In order to cope with the supply pressure, terminal manufacturers need to continuously shorten the terminal R&D cycle, and often need to upgrade the software of a large number of terminals to meet the new needs of customers. Therefore, the efficiency of software upgrade and download has become a constraint on the production cycle. important factor. [0003] Most of the current terminal physical connection methods use Universal Serial Bus (Universal Serial Bus, referred to as USB) to map to a serial device interface for data communication with the computer, or use Universal Asynchronous ...
