Menage the Android memory space

Are you using the pure Android firmware without Ubuntu ?

If that's the case, you can try the following steps.

(WARNING: Please backup all of your important data first!!!)

1. Go to http://wiki.t-firefly.com/index.php/Fir ... h_image/en to get ready for the flashing evironment,

  such as installing rockusb driver, connecting device and configuring AndroidTool.

2. In the extracted directory of AndroidTool_Release_v2.3.rar, use a text editor to open

   "rockdev\rk3288-3.10-uboot-data1G.parameter.txt".

The line prefixed with "CMDLINE:" contains the partition info:

1. CMDLINE:console=ttyFIQ0 androidboot.hardware=rk30board androidboot.console=ttyFIQ0 board.ap_has_alsa=0 init=/init initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),0x00002000@0x00004000(misc),0x00008000@0x00006000(resource),0x00008000@0x0000e000(kernel),0x00010000@0x00016000(boot),0x00010000@0x00026000(recovery),0x0001a000@0x00036000(backup),0x00040000@0x00050000(cache),0x00002000@0x00090000(kpanic),0x00180000@0x00092000(system),0x00002000@0x00212000(metadata),0x00200000@0x00214000(userdata),0x00020000@0x00414000(radical_update),-@0x00434000(user)

Copy the code

The Android data partition is "0x00200000@0x00214000(userdata)", which is in format of "SIZE@OFFSET(PARITION)" with 512 bytes (a traditional disk sector size) as unit.

Therefore, the userdata partition as a size of 0x00200000 * 512 = 1G bytes.

If you want to expand it to 2G bytes. Just change the size to 0x00400000, and adjust all offsets of partitions afterwards.

Here is the full example of 2G userdata partition:

1. FIRMWARE_VER:4.4.2
   
2. MACHINE_MODEL:rk30sdk
   
3. MACHINE_ID:007
   
4. MANUFACTURER:RK30SDK
   
5. MAGIC: 0x5041524B
   
6. ATAG: 0x60000800
   
7. MACHINE: 3066
   
8. CHECK_MASK: 0x80
   
9. PWR_HLD: 0,0,A,0,1
   
10. #KERNEL_IMG: 0x62008000
    
11. #FDT_NAME: rk-kernel.dtb
    
12. #RECOVER_KEY: 1,1,0,20,0
    
13. CMDLINE:console=ttyFIQ0 androidboot.hardware=rk30board androidboot.console=ttyFIQ0 board.ap_has_alsa=0 init=/init initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),0x00002000@0x00004000(misc),0x00008000@0x00006000(resource),0x00008000@0x0000e000(kernel),0x00010000@0x00016000(boot),0x00010000@0x00026000(recovery),0x0001a000@0x00036000(backup),0x00040000@0x00050000(cache),0x00002000@0x00090000(kpanic),0x00180000@0x00092000(system),0x00002000@0x00212000(metadata),0x00400000@0x00214000(userdata),0x00020000@0x00614000(radical_update),-@0x00634000(user)

Copy the code

Save it as new file "rk3288-3.10-uboot-data2G.parameter.txt" in the same directory of the 1G variant.

3. Run AndroidTool.exe (with administrator right if neccessary), follow the steps as shown in the follow image:

4. The device will reboot into Android again. Please do a factory reset and wipe alll the data.

I'm afraid that you cannot do that.




Enlarging Android's userdata paritition will destroy Ubuntu's linuxroot partition.
