MT6763 modem compilation

In the modem section, MTK provides the complete source code only to major smartphone companies like Xiaomi, OPPO, Vivo, and significant design firms such as Huawei Communications, Longqi Technology, and Wentai Technology, as well as module manufacturers like Quectel, Broadlink, Meg, and Ruihai.

Smaller manufacturers receive binary libraries and partially customized parameter source code.

As for the recommended compilation environment, the magnet link provided contains the file “TK_MD_BASIC_MOLY.LR12A.R2.MP.V143.7.tar.zst.”

The version of MIPS gcc should be 2016.05-08

cd ~/modem
cd mcu
ls -a make/projects

you can see
'TK_MD_BASIC(LWCTG_R2_6763).mak' 'TK_MD_BASIC(LWTG_R2_6763).mak'

Start compiling

./m "TK_MD_BASIC(LWTG_R2_6763).mak" new

Before compilation, modifications can be made to the contents of the custom directory at mcu/pcore/custom.

The compiled results will be located in the mcu/build/TK_MD_BASIC/LWTG_R2_6763/bin directory.

The files generated include:

  •  TK_MD_BASIC_MDBIN_PCB01_MT6763_S00.MOLY_LR12A_R2_MP_V143_7.bin (md1bin.img, also known as md1rom)
  • DbgInfo_LR12A.R2.MP_TK_MD_BASIC_MOLY_LR12A_R2_MP_V143_7_2024_02_15_09_49
    – md_all_in_one/single_bin_modem.bin

To execute the script, which is a crucial step, ensure not to overlook it. This script collects all the files that need to be copied to the AP side into the temp_modem folder (located in the modem codebase root directory) and generates an file.

To pack the modem image, execute the following command in the Android source code directory device/mediatek/build/build/tools:


./ ~/mtk/modem/mcu “TK_MD_BASIC(LWCTG_R2_6763).mak”

After executing the command, new modem image files will be generated in the modem code directory modem/mcu/temp_modem.

Finally, modify md1bin.img to md1img.img and place it together with md1dsp.img into the version directory for flashing purposes.
