[0024] Functional Overview

[0025] 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 improves...

Abstract

The invention discloses a signal transmission device and a method. The device is used for transmitting a signal for updating and / or repairing a terminal and can be applied to a communication system comprising software and the terminal. The device comprises a download board control module used for sending a data packet from the software to the terminal and transmitting a signal from the software according to the fact that whether a reply data packet corresponding to the data packet is received from the terminal; a protocol conversion module used for receiving a signal from the download board control module, converting the signal to the signal of a joint test action group (JTAG) and transmitting the converted JTAG signal to the terminal. The invention enhances the efficiency of the updated edition.

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 ...
