Naming Conventions

While there doesn't seem to be a stable pattern that MediaTek SoC names follow between subsequent generations, there are a few naming patterns that are prevalent.

MediaTek SoCs can be split into 5 main categories, each corresponding to a certain period of time where several SoCs were released with highly similar core architectures:

Pattern Common name CPU GPU Modem
MT62** - ARMv5 (ARM7) - 2G
MT65** - ARMv7 (Cortex-A) Mali Utgard, PowerVR SGX 3G
MT67** Helio* ARMv8 (Cortex-A) Mali Midgard, Mali Bifrost, PowerVR Rogue 4G
MT68** Dimensity ≤8000 Mali Valhall 5G
MT69** Dimensity 9000 ARMv8 (Cortex-X + Cortex-A)

*The Helio name wasn't used for MT673* as well as MT6750, MT6752 and MT6753 variants

There are SoCs that don't follow this convention. These SoCs are usually tablet or application variants of the MT6*** SoCs, and have names that follow the MT8*** pattern. For some of those SoCs, the only difference between the mobile and tablet variant is the first digit, while others have completely different names despite them being functionally identical. Here are some known mobile/tablet variant pairs:

Mobile MT6*** Tablet MT8***
MT6580 MT8321
MT6582 MT8382
MT6589 MT8389
MT6592* MT8127*
MT6735 MT8735
MT6771 MT8183
MT6875* MT8192*

*Unconfirmed

Flashing

If you want to flash firmware to Mediatek-based devices, there is a proprietary tool for that: SP Flash Tool. It is e.g. used for the Wiko Lenny 3 (wiko-lenny3).

Some devices also support fastboot, e.g. Sony Xperia XA (sony-tuba), and some support odin, e.g. Samsung Galaxy Grand Prime Plus (samsung-grandpplte).

Some open source software has been developed:

  1. https://github.com/saleemrashid/mediatek_flash_tool has only been tested with the MT6580
  2. https://github.com/MediaTek-Labs/mt76x7-uploader which is compatible with the MT7687 and MT7697 for flashing the bootloader
  3. https://github.com/Wiz-IO/Mediatek-MT2625-Flash-Utility for the MT2625
  4. https://github.com/McBitter/flasher only support for MT6735P, is WIP
  5. https://github.com/bkerler/mtkclient

Enabling previously disabled UART on downstream kernels

Sometimes you might need to get some data from UART on downstream kernel (for example, with intention to debug boot process of your pmOS port) but it's been automatically disabled by the preloader or UBoot or something else. One of the solutions suggested by the official MediaTek OEM FAQ is to run this command as early as possible:

# echo "6 4 1 6" > /proc/sys/kernel/printk

To disable UART logs, run:

# echo "0 0 0 0" > /proc/sys/kernel/printk

Icon TODO: Check if it works on mt67xx devices

Booting procedure

Power applied to the SoC

When chip is powered on the dram controller pushes the address of brom (boot rom, mask rom that is hardwired) to PC (program counter) and execution of rom begins.

Brom execution

  1. UART1 gets initialized to some predetermined baudrate. Baud usually depends in chip input clock source. Observation has been made that UART1 is disabled on many phones, but can be enabled if proper firmware is used and eFuses are not blown.
  2. Initialize storage with low clock. Reason why it's using low clock is because muxes are not programmed at this stage.
  3. Wait for "Start" string on UART1 for unknown amount of time, the internet keeps buzzing about 150ms. After start is recieved, listen to commands from host until jump is observed (refer to brom spec in further reading section). If start is not sent then Preloader image will be loaded from the storage to the SRAM (static ram) and brom loads it. Not sure if flags SP flash tool needs are used at bootup phase.
  4. If KCOL0 pin is shorted to the ground, preloader loading is avoided and download protocol is rolled up on USB port.

Image format

Note Incomplete and has missing information. Feel free to coordinate corrections on Matrix chat. Information here is only for reference. Flashing the binaries to storage will be done using brom protocol and custom flashing software.

This format is used in brom and preloader(has to be verified) while flashing with SP flash tool. All fields are in little endian.
