This repository provides instructions on how to dump and flash LKS32 microcontroller units (MCUs) using a standard ST-Link probe, and how to modify certain parameters. Please check the Disclaimer before proceeding.
- Install python
- Install
pyocdwith pip:pip install pyocd - Download and extract the appropriate Pack file:
The image is showing Brightway "3 Lite" controller. TP locations can vary across controllers.
Using pyocd and the Pack file downloaded before, see examples below.
LKS32MC08x:
python -m pyocd cmd -c savemem 0 0x10000 mcu_fw.bin --pack Linko.LKS08x.1.1.7.pack --target lks32mc081c8t8
LKS32MC07x:
python -m pyocd cmd -c savemem 0 0x20000 mcu_fw.bin --pack Linko.LKS07x.1.1.7.pack --target lks32mc071cbt8
Copy mcu_fw.bin to mcu_fw_mod.bin and make changes. See Modifications for examples.
Using pyocd and the Pack file downloaded before, see examples below.
LKS32MC08x:
python -m pyocd load mcu_fw_mod.bin --pack Linko.LKS08x.1.1.4.pack --target lks32mc081c8t8
LKS32MC08x:
python -m pyocd load mcu_fw.bin --pack Linko.LKS07x.1.1.7.pack --target lks32mc071cbt8
Simply run the above command with mcu_fw.bin instead of mcu_fw_mod.bin.
Advise: Keep the original binary in a safe place!
- Download the SN script
- Using the script:
python bw_change_sn.py mcu_fw_mod.bin <SN>
For <SN> check the following table.

| 4 | 46441 |
| 4 Lite | 46419 |
| 4 Ultra | 37829 |
| 5 | 60562 |
