Bạn ơi. Cái này mình đã cài roài, nhưng cài xong thì máy mình chỉ đổi SPL thui, chứ IPL thì vẫn y như cũ hà, ko bik tại sao nữa :O. Mà nếu mình ko đổi IPL thì khi up ROM có bị j ko?
The Boot Process
Power up and initialization: After system power up, the IPL code that resides on the XIP
block of the DiskOnChip is executed. The IPL code initializes the DiskOnChip controller
and the RAM.
Copying the SPL code from DiskOnChip to RAM: After initialization, the IPL reads and
loads the SPL code from the DiskOnChip binary partition to RAM. It then jumps to the SPL
start address in RAM and executes the SPL.
Notes: 1. In general, the IPL is limited in size to several KB (the size limitation varies,
depending on the device type), so it is not possible to include both the system
initialization code and the error correction code. The absence of the error correction code in the IPL is the reason why the boot process is divided into the IPL stage and SPL stage. The actual loading of the OS image to RAM is done by the SPL code. Since the SPL runs in the system RAM, there is no limit on code size and it can include the error correction code.
2. It is recommended to store the SPL code and the OS image on two separate binary
partitions.
Copying the OS image from DiskOnChip to RAM: The SPL performs the required
initializations, and then reads the OS image from the binary partition and loads it to RAM. Accessing the binary partition and loading the OS image is done using a combination of the BDK code, which enables accessing the DiskOnChip binary partition, and the OS boot
loader, which enables loading the specific OS to the RAM. The software tools for
programming and loading the boot loader are provided in this guide and discussed in depth.
Starting the OS after it is copied to RAM: An OS-dependent code.
At this stage the boot process is complete. The OS image usually contains a TrueFFS driver for DiskOnChip that enables accessing the device disk partition.
=> túm lại là IPL đời cao thì tốt hơn thui, còn có bị "làm sao" ko thì bác quan tâm tới SPL là đc, theo thông tin của bác thì máy bác đã chạy Hard SPL 3.07(tức là bác up các bản rom trên diễn đàn thoải mái mà spl của bác sau mỗi lần up ko thay đổi) . để up IPL lên bác có thể up qua bản rom
http://rapidshare.com/files/1584103..._3.07.720.03_4.1.13.71_03.34.90_BLUE_Ship.exe (chú ý là rom này cho ELFin-htc touch 2 nhé) , hoặc bản rom nào có kèm theo IPL
sau khi up xong máy bác sẽ có thông số IPL như mong muốn => bác có thể up bản khác theo ý thick' (ko gồm IPL)
