Abstract
The invention discloses a method of burning EC (embedded controller) firmware in made-in-China computer platforms. The method includes: adding a functional interface FlashEC to an EC code to upwardly receive an ACPI (advanced configuration and power interface) command and to downwardly operate a SPIFLASH (serial peripheral interface flash) according to such command; adding a copy function to the EC code, finding an on-chip memory from an EC on-chip RAM (random access memory), copying a functional interface function from the FLASH to the EC on-chip RAM, and after copying, and directly redirecting to a FlashEC entry of the EC on-chip RAM to perform execution; running a burn application program running in an EFIShell environment to communicate with an EC, interact with FlashEC () of the EC, read binary files of the EC, transmit commands and data and transmit the data to the FlashEC. The method has the advantages that software burning tools can be used in mobile disks to burn the ECs under the EFIShell environments of the made-in-China computer platforms, the trouble of disassembly is omitted, and time of burning the EC firmware is greatly saved.
Description
Technical field
The present invention relates to EC firmware techniques field, be specifically related to a kind of method of home brewed computer platform burning EC firmware.
Technical background
Nowadays, the notebook of Domestic Platform starts slowly to rise.At use Godson, when the domestic CPU such as Shen Wei manufactures notebook, a chip being called EC can be used.EC chip is except CPU, outside the bridge of north and south, and an other important chip on mainboard.Use EC can do built-in keybad, touch pad, battery management, fan control, the functions such as power supply sequential.
In X86 computer industry, the software burning of EC is all carried out under DOS.But because domestic CPU can not run DOS system, so the software replication tool that EC manufacturer provides also cannot use.So can only the burning of choice for use cd-rom recorder or use debugging acid JTAG burning.Use cd-rom recorder burning, first will take casing apart, then take out the FLASH on mainboard, use corresponding cd-rom recorder to drive, coordinate cd-rom recorder to carry out programming.Use JTAG burning, first casing will be opened, debug machine and target mainboard are connected, then use the drive software of EC JTAG to carry out programming.No matter choice for use cd-rom recorder or select JTAG, when upgrading EC firmware, all invariably cannot will take machine apart, exposing mainboard, and then burning.The machine of tearing open needs to have gained some understanding to machine element, even if understand machine element, also the regular hour will be spent to take casing apart.So just cause the waste of manpower and unnecessary trouble.
Summary of the invention
The technical problem to be solved in the present invention is: the present invention is in order to solve this trouble, write the software replication tool under a Domestic Platform, can under the EFI SHELL environment under Domestic Platform, software replication tool is placed in mobile disk burning is carried out to EC, so both eliminate the trouble of the machine of tearing open, and greatly save the time that burning EC firmware spends.
The present invention needs the realization of two parts function, and a part will add interface code (LPC communication communicates with SPI) in EC code, and another part will write a burning application tool under EFI SHELL.
The technical solution adopted in the present invention is:
A method for home brewed computer platform burning EC firmware, described method is included in EC code, adds functional interface FlashEC, up receives ACPI order, down according to command operation SPI FLASH;
A copy function is added in EC code, when program of writing with a brush dipped in Chinese ink is run, EC functional interface function can not operate in EC FLASH, so a slice internal memory will be found out in RAM on EC sheet, functional interface function to be copied to EC sheet in RAM from FLASH, after having copied, the FlashEC porch directly jumping into RAM on EC sheet performs;
Run a burning application program run in EFI Shell environment, be responsible for communicating with EC, mutual with the FashEC () in EC, be responsible for reading EC binary file, send order and send data, its data are passed to FlashEC.
Described data refer to EC firmware content.
Described order comprises chip erase command, sector check command, sector erasing order, page program command and dragging down with CS level, and CS level is drawn high.
In described method, the flow process of EC burning interface is:
1) EC is started;
2) programming pattern is entered;
3) forbid all interruptions of EC, copy on EC programming code all FLASH in RAM, and give programming code by program control power;
4) judged whether that order is sent to;
5) the finish command is judged whether;
6) when selecting no, fill order also repeats step 4;
7) when selecting to be, terminate.
The flow process of described burning application program is:
1) start, send FLASH device detection and receive orders, fetch equipment model;
2) read configuration file, determine the order code corresponding to command adapted thereto;
3) select printer function option: 1, download FLASH data, 2, fast programming FLASH, 3 programme FLASH entirely;
4) select 1, create message part, send order, and be saved in file, step 11)
5) select 2, open the file wanting burning, and file reading size, calculate the sector number that it takies, then verification also burning from first sector;
6) judge all whether all burning is complete in sector, in this way, then step 11)
7) as no, then carry out sector verification, judge that whether FLASH is consistent with file content, in this way, then repeat step 6);
8) as no, then carry out sector erasing, by Page Program, file content is burnt to current sector, then repeats step 6);
6) select 3, open the file wanting burning, and file reading size, calculate the sector number that it takies;
7) chip erase is carried out;
8) verification also burning from first sector;
9) judge all whether all burning is complete in sector, in this way, then step 11)
10) as no, by Page Program, file content is burnt to current sector, then repeats step 9);
11) EOP (end of program).
Beneficial effect of the present invention is: the present invention can under the EFI SHELL environment under Domestic Platform, software replication tool is placed in mobile disk burning is carried out to EC, so both eliminate the trouble of the machine of tearing open, and greatly save the time that burning EC firmware spends.
