[Tutorial] How to create scatter file for Mediatek devices

(16-04-2016, 09:40 PM)hovatek Creating a scatter file for an MTK Android phone was very easy in older Mediatek phones using the MTK Droid Tools method @ https://www.hovatek.com/forum/thread-2163.html. However, the latest version of MTK Droid Tools as at the time of this post (V 2.5.3) doesn't support the newer MTK Chipsets so the above method wont work.
Why would I want to manually create a scatter file?
As I earlier said, backing up a working phone (running on the newer chipsets) using the MTK Droid Tools method @ https://www.hovatek.com/forum/thread-468.html wont work. To backup such phones, you would need to do an SP flash tool readback using https://www.hovatek.com/forum/thread-526.html and backup one partition at a time (since MTK Droid Tools can't process ROM_0). The problem is you'll need a scatter file to do an SP Flash tool readback; so you're kind of back to square one.
The good news is that you can manually create or modify a scatter file to work for your device; making a backup via SP Flash Tool readback possible. Now, you know why you might need to modify a scatter file in certain situations.
Requirements
* MTK Droid tools & PdaNet (see https://www.hovatek.com/forum/thread-468.html)
* Download a scatter file for the phone's chipset (e.g MT65**_Android_scatter) @ https://www.hovatek.com/forum/thread-12724.html
* Notepad++ (Download @ https://notepad-plus-plus.org/)
Procedure
1. Setup MTK Droid Tools on the PC to ensure the phone gets detected
2. If the phone still doesn't get detected despite installing necessary drivers then it must be an ADB clash, fix that using https://www.hovatek.com/forum/thread-10111.html
3. Once the phone gets detected, click on Blocks Map
4. You should see something like in the image below
5. Open the scatter file using Notepad++, its content should look something like

6. You will be modifying platform, linear_start_addr, physical_start_addr and partition_size
7. platform: MT65** must be the exact chipset of the phone e.g platform: MT6580 . Note that the scatter file for this example would then be named MT6580_Android_scatter
8. linear_start_addr will have the same value as physical_start_addr. To get this value for a given partition, you open the Blocks Map and convert the value under the Scatter column (for that partition) to Hex by replacing all Zeros (0) in front of the first non-Zero character with 0x
For example, in the image above, the Scatter value for recovery is 0002F80000; therefore, linear_start_addr = physical_start_addr = 0x2F80000
For boot, Scatter value = 0002980000 therefore, linear_start_addr = physical_start_addr = 0x2980000
9. For partition_size, you do the same as above but with the Size column. Recovery in the image above has a Size value of 0000600000; therefore, partition_size = 0x600000
10. Modify the values for each partition in the scatter file using the values from the Blocks Map then save.
11. You can then load the scatter file (click Scatter loading) in SP flash tool @ https://www.hovatek.com/forum/thread-159.html. If you did all correctly then the scatter file should be loaded without an error
Questions & Answers
Q: There are some partitions in the scatter file but not in my phone's Blocks Map, what values do I enter for such partitions in the scatter file
A: Just delete that whole record from the scatter file. One record is often something like
Code:- partition_index: SYS28 partition_name: sgpt file_name: NONE is_download: false type: NORMAL_ROM linear_start_addr: 0xFFFF0004 physical_start_addr: 0xFFFF0004 partition_size: 0x80000 region: EMMC_USER storage: HW_STORAGE_EMMC boundary_check: false is_reserved: true operation_type: RESERVED reserve: 0x00

showing only 1 which is bmtpool
but the create scatter file is not active.
the scatter file i downloaded is showing
1 PRELOADER 0X. with serial no. continuing down
means MTK Droid tools doesn't support your device

Your example scatter file for my MT8127 (https://www.hovatek.com/forum/thread-12724.html) contains a FAT partitions which isn't on my device, OK, I will delete it the entire partition.
But I have a "custpack" partition with ext4 and mountpoint.
As I see there are other ext4 partitions (android,cache,usrdata) with the exact same properties (like type, is_reserved,operation_type, etc)
Can I add a new partition with the proper partition_index?

remove the FAT from the list.
You can add a new partition so far you get the details right

One last question:
I have a bmtpool partition which start at 0x1500000 and end at 0x2A00000 (the size is 0x1500000)...
https://img42.com/dxARr
but this section contains also the protect_s, seccfg, uboot and part of bootimg partition too. Did I make a mistake in my calculation?

Port CWM, Carliv or Philz recovery instead
