fastboot 烧写内核

夏新N80手机，很久没用，今天想试试自己的kernel性能，插上进不了串口，问人才知道OBM关了开机进入串口模式，得开机时按下 向下键才能进入串口模式，而且N80的bug，还不能插上串口开机，
不如试试fastboot 烧 kernel记录如下，防止忘记：
先下载fastboot工具放在桌面上，然后：
b186@b186-desktop:~/桌面$ sudo ./fastboot erase boot
sudo: ./fastboot: command not found
b186@b186-desktop:~/桌面$ chmod +x fastboot
b186@b186-desktop:~/桌面$ sudo ./fastboot erase boot
< waiting for device >
erasing 'boot'... OKAY
b186@b186-desktop:~/桌面$ sudo ./fastboot flash boot ~/svn/lnx2632pxa/arch/arm/boot/zImage
sending 'boot' (1916 KB)... OKAY
writing 'boot'... OKAY
b186@b186-desktop:~/桌面$ sudo ./fastboot reboot
rebooting...

Common commands

TTC_DKB>> tftp zImage

TTC_DKB>> tftp uboot
TTC_DKB>> w -u               // burn uboot
TTC_DKB>> tftp ramdisk

Fastboot burn image

1. download the attachment
2. enter uboot, input command "fb" to enable fastboot function.
   TTC_DKB>> fb

3. Input these commands on PC to burn image,

sudo ./fastboot burn [image name] [-z {raw image}|-y {yaffs}] [offset in NAND]
sudo ./fastboot burn erase 0x920000 0x280000   //earse zImage
sudo ./fastboot burn zImage -z 0x920000 //burn zImage

if ramdisk.img size is 512K, we can use following command to burn ramdisk.
sudo ./fastboot burn erase 0xba0000 0x80000   //earse ramdisk
sudo ./fastboot burn ramdisk_len.img -z 0xba0000 //burn ramdisk

sudo ./fastboot erase system   //erase system
sudo ./fastboot flash system system.img  //burn system
sudo ./fastboot burn system.img -y 0xf20000 //burn system
sudo ./fastboot erase opl      //erase opl
sudo ./fastboot flash opl opl.img    //burn opl
sudo ./fastboot burn opl.img -y 0xcf20000 //burn opl
sudo ./fastboot erase userdata   //erase userdata
sudo ./fastboot flash userdata userdata.img   //erase userdata
sudo ./fastboot burn userdata.img -y 0x118a0000 //burn userdata

sudo fastboot burn erase 0x120000  0x800000 //erase the whole cp
sudo fastboot burn Arbel.bin -z 0x120000  //flash the arbel
sudo fastboot burn TTC1_M06_AI_A0_Flash.bin  -z 0x820000 //TTC

What is fastboot?
Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images.

Known issue:
Some buffers(frame buffer .etc) use fixed address which may overlape with other(usb buffer .etc) then cause issues.

Fastboot usage:

1) HowTO create boot.img:
==============================
./mkbootimg --kernel zImage-borqs --ramdisk ramdisk.img -o boot.img

2) HowTO flash:
==============================

i) Press power key + home key enter fastboot mode.

ii) Connect to PC via USB cable and flash mobile using below commands:
sudo ./fastboot flash boot boot.img
sudo ./fastboot flash system system.img
sudo ./fastboot flash opl opl.img
