Actual operating position of the present invention is following:

The burn a CD method of ROM of mobile phone of the present invention is to write mobile phone EFS mirror image to the packing of CD mirroring ISO file to produce, and when handset starting, accomplishes the work that is burnt to CD mirroring ISO file mobile phone USB-CDROM by mobile phone.

Mobile phone NAND Flash marks off a FTL2 subregion more, is used to store the CDROM file content.

Increased mobile phone USB-CDROM below and can correctly have been discerned more necessary contents by PC:

Changed the block size of mobile phone FTL2 subregion, thereby can correctly read and write the UDF file system of 2048 block of bytes size at the SCSI of PC end.

Changed the device type descriptor of USB flash disk, in the demonstration of PC end is CDROM equipment rather than USB flash disk equipment.

Increased the peculiar SCSI CMD43 of USB-CDROM (read toc), SCSI CMD 4601, SCSICMD4600, SCSI CDM51, the response of SCSI CMD 4A makes Linux and Windows system all can correctly discern USB-CDROM.

As shown in Figure 1, in fact the imprinting of mobile phone CDROM is divided into plurality of processes, is the flow process of producing below:

(a) making of ISO file mirror image

Use UltraISO to make the optical data disk of a UDF form, its content is that mobile phone that mobile phone CDROM comprises drives with the mobile phone synchronization means etc., and size is made the back change that finishes and is called cdrom.iso about 10M.

(b) mobile phone EFS mirror image is made

Use a mobile phone of opening EFS mirror image export function, use the W80 mobile phone of high pass 6270 platforms here, pull cdrom.iso tool using EfsExplorer into the root directory of mobile phone file system.Do not restart that tool using qpst backs up out under the situation of mobile phone to the file system of current phone then, be stored as the efs.mbn file.

(c) mobile phone factorylmage makes

Use high pass Qfit instrument, produce the total program mirror image of the mobile phone Factorylmage.mbn file that has program and file system mirror image to the packing of efs.mbn file.

(d) production of mobile phone

Use download tool, download to the Factorylmage.mbn file among the NandFlash of mobile phone.

(e) mobile phone is to the operation of ISO image file

Mobile phone is after program is downloaded; Whether can check during startup has the cdrom.iso file to exist in the file system; If have, so just write the FTL2 subregion of Nand Flash to the content that changes mirror image by piece, this subregion is that USB-CDROM creates; Its size is 16M, is large enough to hold the ISO mirror image of 10M size.Write finish after, deletion cdrom.iso file.

(f) mobile phone CDROM imprinting finishes, and at this moment connects USB and can see USB-CDROM to computer

When connecting computer, the content of the USB-CDROM that computer is seen is consistent with content in the ISO mirror image.At this moment can move or duplicate the content among the mobile phone CDROM, its form is the UDF form.

After production finishes, if the content of the CDROM that only upgrades can be used following flow process:

(a) use EfsExplorer to pull the cdrom.iso file of making in the mobile phone file system root directory into.This process need mobile phone file system has the above enough spaces of 10M to hold the cdrom.iso file.

(b) restart mobile phone, whether mobile phone can exist by self-verifying cdrom.iso file when startup, can be burnt to it in the FTL2 subregion so if exist, and the imprinting process probably needed for 15 seconds, and USB-CDROM promptly can use after imprinting finished.

After if production finishes; Need upgrade the simultaneously content of mobile phone Efs file system and CDROM; Can use (b) in the production procedure to generate the mobile phone file system mirror image efs.mbn that has cdrom.iso so, use download tool Qpst that it is directly downloaded to mobile phone and restarts and get final product.

Introduce of the change of mobile phone FTL2 blockette size below from 512 bytes to 2048 bytes:

The default tile size of mobile phone FTL2 subregion is 512 bytes, if change to 2048 bytes, the logical block number should change to 1/4 of original number so, and the read-write logical block size of transmitting in the SCSI read write command will multiply by 4.

Simultaneously in the fetch equipment capacity command of SCSI CMD25, the pairing block size of FTL2 is changed to 2048, number of blocks changes to original 1/4.

Introduce mobile phone USB-CDROM below and can correctly be discerned necessary scsi command by PC:

SCSI?CMD?12(inquriy)

When equipment was CDROM, returning device type was 5, when equipment is USB flash disk, returns 0.

SCSI CMD43 (read toc), SCSI CMD 4601, SCSI CMD4600, SCSI CDM51, these orders of SCSICMD 4A are that the optical data disk answer gets final product by device type in the SCSI standard.

To sum up can know,, no longer need increase treatment scheme to mobile phone CDROM owing to adopted above-mentioned technology, mobile phone of the present invention to burn a CD the method for ROM when producing.When program upgrade, new mobile phone EFS mirror image only need be provided and download to mobile phone to get final product, exempt complicated operations and flow process.Can greatly save equipment input, the human input that is used to produce like this, reach and reduce expenses, the effect that reduces cost.After production or program upgrade finish, connect mobile phone and PC, can see that content is the compact disk equipment of the ISO mirror image of institute's imprinting at the PC end through the USB line.
