Description

A kind of method for burn-recording that improves VR chip FW burning efficiency

Technical field

The present invention relates to server master board manufacture craft field, relate to a kind of method for burn-recording of the VR of raising chip FW burning efficiency.

Background technology

Follow the arrival of digital Age, digital technology has been penetrated into the every field of people's daily life.Such as: the server of TV, washing machine, mobile phone and even data center module.Digital signal has: strong interference immunity, be convenient to the accuracy advantages of higher of computing machine identifying processing, good confidentiality, signal transmission of information.Along with the widespread use of digital technology, as the foundation stone of server steady operation---power supply, also start to realize the control to switch change-over with digital form, i.e. digital power technology.

Digital power belongs to a closed-loop control system, by power output end voltage is sampled, then the magnitude of voltage of sampling is done to digitized processing, and the digital signal after processing is inputed to power supply control chip carry out calculation process, produce suitable pwm signal and come the conducting of gauge tap metal-oxide-semiconductor to turn-off, finally by output filtering link, realize the stable output of voltage.To ensure the normal pulse of server in all Client applications.

Critical component---the mainboard of server, and the CPU on mainboard at present and internal memory power supply plan have started the application of digital power technology, and realize the batch of product.In server master board PCB design process, for guaranteeing that the output voltage of all digital VR can meet design requirement, and need to adjust the FW of VR chip; Because the LAYOUT of the VR circuit of different CPU and internal memory there are differences, will cause like this FW of final optimization pass also can be different.Such as: when a block server mainboard includes 2 CPU, 4 groups of internal memories, the burning plate that the FW after optimization needs YongVR manufacturer to provide passes through the address of I2C scan bus VR chip on mainboard.For 2 groups of CPU VR chips and 4 groups of internal memory VR chips, scan one by one, then select corresponding VR chip, by the I2C interface on burning plate, FW information is burnt in VR chip; Do not select a VR chip, do burning action, so, the burning that completes monoblock mainboard CPU and internal memory VR chip FW need to be done 6 burnings operation.

When server master board is produced in batches, the burning link of VR chip can become the bottleneck of production efficiency.

Summary of the invention

For addressing the above problem, a kind of method for burn-recording of the VR of raising chip FW burning efficiency is proposed herein, the method can, by under dos command, directly be moved errorlevel.Can complete 2 groups of CPU VR chips of the mainboard shown in example and 4 groups of internal memory VR chips.The burning that completes monoblock mainboard CPU and internal memory VR chip FW only need to be done 1 burning operation.

When mainboard VR chip FW is done to online burning according to following steps:

1) the hardware preparatory stage:

Take (at the mainboard as cited above) after mainboard, be ready to start USB flash disk, and on mainboard, install CPU and internal memory (the voltage fluctuation risk of bringing for the initial code of VR chip guaranteeing on mainboard, general 1 CPU and 1 root memory installed, to realize, minimize the lower normal boot-strap of configuration, enter DOS environment); With PSU, be connected with mainboard, realize to main board power supply;

2) the software preparation stage:

First compiled replication tool: VRPro.exe; Then, be ready to VR chip and want the FW file of burning and autoexec (such as AB.txt, CD.txt, EF.txt, GH.txt, CPU0.txt, CPU1.txt, VR_CODE.bat);

3) the FW burning stage:

File copy above, to starting after USB flash disk, is plugged on USB flash disk in the USB interface of mainboard, and start enters dos command prompt symbol, then keys in: VR_CODE.bat, carriage return; System can automatically perform the burning operation of VR chip FW;

4) burning is confirmed:

(this confirmation also can be self-defined by software engineer).

Above, for a kind of real case step that improves the method for burn-recording of VR FW burning efficiency, describe, according to above operating process, can realize the burning of VR FW.

The invention has the beneficial effects as follows:

1) by entering under DOS environment, under dos command prompt symbol, directly move an autoexec, can realize fast writing with a brush dipped in Chinese ink of CPU and internal memory VR chip FW on mainboard;

2) can disposablely realize the FW burning of many group VR chips on mainboard, simple and fast.

Accompanying drawing explanation

Accompanying drawing 1 is workflow schematic diagram of the present invention.

Accompanying drawing 2 is mainboard schematic diagram of embodiment.

Embodiment

Embodiment: for making the object, technical solutions and advantages of the present invention clearer, do further and describe in detail below in conjunction with 2 couples of the present invention of accompanying drawing.

The present invention proposes a kind of method for burn-recording of the VR of raising chip FW burning efficiency.As shown in Figure 2: be the mainboard of two CPU, 4 groups of memory configurations, wherein every CPU, every group of internal memory are realized voltage transitions power supply by independent VR.Together with VR chip is interconnected at the ME unit in PCH by SMBUS bus (for I2C bus).By writing with a brush dipped in Chinese ink Software tool VRPro.exe, realize ME unit in mainboard PCH the read-write of VR chip FW data is controlled.

VR chip FW is made into autoexec to be kept in startup USB flash disk.The mainboard of Fig. 2 of take is example, definition:

The name of 4 groups of internal memory VR chip FW is called: AB.txt, CD.txt, EF.txt, GH.txt, and corresponding I2C address is followed successively by: addr1, addr2, addr3, addr4;

The name of CPU0 and CPU1 VR chip FW is called: CPU0.txt, CPU1.txt, and corresponding I2C address is followed successively by: addr5, addr6;

Autoexec: VR_CODE.bat thes contents are as follows:

VRPro.exe addr1 AB.txt

VRPro.exe addr2 CD.txt

VRPro.exe addr3 EF.txt

VRPro.exe addr4 GH.txt

VRPro.exe addr5 CPU0.txt

VRPro.exe addr6 CPU1.txt

When FW burning, the preparation of hardware aspect is as follows: on mainboard, install CPU and internal memory, by starting USB flash disk, be plugged in the USB interface of mainboard, with PSU to main board power supply; After mainboard start, enter DOS environment, under command prompt, operation is to order:

VR_CODE. bat

Can realize a burning of 6 groups of VR chips of mainboard is completed.
