21 Outline Introduction Motivation Porting Procedure Building Environment Conclusion 21 Android Porting 實際硬體平台移植 Copyright Mask.
22 Motivation Build a new experimental Android platform Study how Linux device drivers cooperate with Android applications Open Source Share Android Porting experience Prove Android could run on PXA Android Porting 實際硬體平台移植 Copyright Mask.
23 Outline Introduction Motivation Porting Procedure Building Environment Conclusion 23 Android Porting 實際硬體平台移植 Copyright Mask.
24 Key Points of Building An Android Runtime System Carefulness Luckiness Experience 24 Android Porting 實際硬體平台移植 Copyright Mask.
25 Porting Steps 25 Android Porting 實際硬體平台移植 Copyright Mask.
26 How to Construct Linux Kernel with Android Patch There are different ways to patch Linux kernel depending on different situations 26 Android Porting 實際硬體平台移植 Copyright Mask.
27 Use Which Tools to Patch Linux Kernel Linux platform Meld Windows platform WinMerge 27 Android Porting 實際硬體平台移植 Copyright Mask.
28 Meld 28 Android Porting 實際硬體平台移植 Copyright Mask.
29 WinMerge 29 Android Porting 實際硬體平台移植 Copyright Mask.
30 Potential Problems on Patching Linux Kernel Data structure Reference similar platforms Init section Reference successfully compiled drivers Source dispersed Only consider the BSP changed from the official Linux Kernel File name changed Same as the previous item Kernel configuration 1 st stage make oldconfig make platform_old_defconfig 2 nd stage Depend on your requirements to adjust 30 Android Porting 實際硬體平台移植 Copyright Mask.
31 How to Fix Compiling Problems Refer to kernel source of similar platforms Mainstone (PXA270) Refer to the workable BSP from vendor from vendor 31 Android Porting 實際硬體平台移植 Copyright Mask.
32 Use Easy Ways to Debug Linux Kernel Enable options in the kernel configuration CONFIG_DEBUG_KERNEL If you want to get more debug informations CONFIG_DEBUG_DRIVER CONFIG_DEBUG_DEVRES make V=1 Get detail information during compiling process 32 Android Porting 實際硬體平台移植 Copyright Mask.
33 Which Drivers May Need to Modify Serial NIC Framebuffer USB Touch Keypad Etc. 33 Android Porting 實際硬體平台移植 Copyright Mask.
34 LCD Flickering Problem (linux/drivers/video/pxafb.c) Problem LCD Screen Flicker 34 Android Porting 實際硬體平台移植 Copyright Mask.
35 LCD Flickering Problem (cont) Cause LCD controller is enabled and then disabled repeatedly It s cause by the register LCCR0 is not properly synchronized in pxafb.c, which then falsely switches the status of LCD Solution Add fb_pan_display() to change LCD states accordingly 35 Android Porting 實際硬體平台移植 Copyright Mask.
36 Keypad Driver (linux/drivers/input/keyboard/android_keypad.c) Problem Only 16 keys The keypad device doesn t use IRQ Solution Composed key KEY_MENU KEY_BACK kthread Polling Idle algorithm Incrementally double the idle time until reaching the maximum idle time 36 Android Porting 實際硬體平台移植 Copyright Mask.
37 Touch Panel Driver (linux/drivers/input/touchscreen/ucb1400_ts.c) Modification Assign IRQ number to 161 Connected to input subsystem Calibrate (x,y) position Adjust touch sensitive 37 Android Porting 實際硬體平台移植 Copyright Mask.
38 How to Trace Android Source Code ctags --C++-kinds=+p -R 38 Android Porting 實際硬體平台移植 Copyright Mask.
39 It Seems Android Gets Wrong (x,y) Positions from Touch Driver Problem The touch driver gets the (x,y) position successfully but Android always reports the (0,0) to applications Analysis Did (x,y) report to the user space correctly? Did Android get the correct (x,y)? Did Android modify the (x,y) somewhere? Why Android modify the (x,y)? Cause The reporting (x,y) relates to the LCD status The LCD status relates to the power status 39 Android Porting 實際硬體平台移植 Copyright Mask.
40 Android Gets The Touch Device 40 Android Porting 實際硬體平台移植 Copyright Mask.
41 Android BatteryService Workflow 41 Android Porting 實際硬體平台移植 Copyright Mask.
