Standard scatter files limit USB handshake intervals. To make flashing better (faster), you need to modify the download agent behavior—not the scatter itself, but you can embed hints.
At the bottom of your scatter file, add:
[CONFIG]
DA_HIGHSPEED=1
BROM_PRELOADER_DELAY=50
- partition_index: 6
partition_name: boot
file_name: boot.img
is_download: true
type: NORMAL
linear_start_addr: 0x700000
physical_start_addr: 0x700000
partition_size: 0x2000000
region: EMMC_USER
storage: HW_STORAGE_EMMC
boundary_check: true
is_reserved: false
operation_type: UPDATE
reserve: 0x00
The Mediatek Download Agent (DA) is version-sensitive. A scatter file created with DA version 3.0 might fail with DA 4.0. To make your mt6768androidscattertxt universally better, include compatibility signatures:
__DA_VERSION__ = 4.0+
__SECURE_BOOT__ = false
__DA_VENDOR_ID__ = 0x0e8d
This tells any modern DA tool (SP Flash Tool v5.21+) to ignore obsolete security checks.
| Error in SP Flash Tool | Cause in Scatter |
|------------------------|------------------|
| STATUS_DA_HASH_MISMATCH | Wrong preloader address or size |
| STATUS_EXT_RAM_EXCEPTION | Incorrect pgpt or boot_para offset |
| S_DL_GET_DRAM_SETTING_FAIL | Partition layout mismatches DRAM init |
| STATUS_SECURE_CFG_DOWNLOAD_NOT_ALLOW | Unprotected seccfg or keystore partition download enabled |
