Abstract

The invention discloses a USB (universal serial bus) burning device for directly burning an SPI ROM (serial peripheral interface read only memory) on a mainboard. The USB burning device comprises a plurality of clamping structures, a power source, an SPI burning connector, a burner and a computer for burning, one ends of the clamping structures clamp a power source pin, a grounding pin and a plurality of other pins in one-to-one correspondence, the power source comprises a forward end and a grounding end, the forward end is electrically connected with the other ends of the clamping structures clamping the power source pin, the grounding end is electrically connected with the other ends of the clamping structures clamping the ground pin, the other ends of the clamping structures clamping the ground pin and the other pins are all connected to the SPI burning connector, the burner comprises an SPI burning port connected with the SPI burning connector, and the computer for burning comprises an USB port connected with a USB port of the burner. By the USB burning device, programs can be burned without demounting the SPI ROM from the mainboard.

Description

[0001] 【Technical field】 [0002] The invention relates to a burning device of SPI ROM, in particular to a USB burning device for directly burning SPI ROM on a main board. [0003] 【Background technique】 [0004] When the factory analyzes or repairs the motherboard that does not display after booting, it often needs to reprogram the SPI (Serial Peripheral Interface--Serial Peripheral Interface) ROM (Read-Only Memory--read-only memory). [0005] The current method is usually to replace the SPI ROM, and the current SPI ROM is an integrated circuit with 8pin or above, which requires the use of a heat gun and an electric soldering iron to disassemble the SPI ROM. After that, take the replaced SPI ROM to the burning room for burning, and then install the SPI ROM on the motherboard after burning. In this way, it is time-consuming and laborious, which affects the efficiency of analysis and maintenance, and the multiple installation and removal of the SPI ROM will also affect the serv...
