Embodiment Construction
[0047] Burning device of the present invention such as Figure 1a As shown, the burning device 101 includes a burning circuit 104 and a burning jig 102 . The burning circuit 104 is a BOOTROM that has been burned outside the board, and the target circuit 105 is the BOOTROM that needs to be burned in the target system 103 . The burning circuit 104 and the target circuit 105 are fixedly connected on the burning target single board by the burning fixture 102, and the burning target single board loaded with the burning device 101 is as follows: Figure 1b shown. The models of the replacement circuit 204 and the target circuit 105 are exactly the same or the circuit parameters are consistent, and the pins of the two BOOTROMs correspond one to one. In order to prevent bus conflicts when the two BOOTROMs are accessed by the processor, the control signals (such as CS chip select signals) of the two BOOTROMs need to be processed separately, that is, to ensure that the two BOOTROMs cann...

The utility model discloses a method of achieving on-board imprinting of the processor system BOOTROM; wherein, the steps comprise: connecting the imprinting device with an imprinting circuit with the imprinting jig to the target circuit on the imprinting target single board; enabling the replacement circuit of the imprinting circuit while disenabling the target circuit through switching the circuit; the target system starting from the replacement circuit, enabling the target circuit while disenabling the replacement circuit through switching the circuit; the target system reading the imprinting mapping into the target circuit. The method of the utility model can remove the jack of BOOTROM directly and achieve the BOOTROM on-board imprinting after the inserted BOOTROM is welded to the single board directly, which has the advantages of not changing the original design, not adding the design cost of the software and hardware of the single board, and having easy operation.
Description
technical field [0001] The invention relates to a device and a method for burning a boot code chip (BOOTROM) of a processor system, in particular to a device and a method for burning a BOOTROM on a board. Background technique [0002] Existing processor systems all have a BOOTROM for storing startup programs. Usually, the BOOTROM selects a low-cost plug-in flash memory (FLASH) chip, burns the startup program into the FLASH through the burner, and then inserts the FLASH into the corresponding socket of the single board as the BOOTROM of the processor. [0003] During production, processing, transportation, and use, problems such as damage to the BOOTROM socket and poor contact of the BOOTROM often occur due to the socket, so removing the BOOTROM socket and directly soldering the BOOTROM to the board has become a requirement. However, if you remove the BOOTROM socket, you will face the problem of how to burn the BOOTROM on the board. [0004] In the Chinese patent 02125596.2...
