Chip testing tool

The utility model relates to a chip testing tool which comprises a first circuit board, a flexible circuit board and a second circuit board. The first circuit board is suitable for being arranged on one side of the embedded system board; the first circuit board is electrically connected with the second circuit board through the flexible circuit board; the second circuit board is provided with a logic analyzer interface circuit, a serial port debugging interface circuit and a Socket seat; the Socket seat is arranged on one side of the second circuit board, and the Socket seat is detachably connected with the chip to be tested; the logic analyzer interface circuit and the serial port debugging interface circuit are electrically connected with the Socket seat. The to-be-tested eMMC chip is placed in the Socket seat and taken out and replaced with a new to-be-tested eMMC chip after the test is completed, the eMMC chip is not directly welded to the embedded system board, the eMMC chip and the embedded system board
