Jlink Download
Use J-Link debugger to flash firmware (.bin or .hex) to ARM Cortex-M microcontrollers, supporting GD32/STM32 and other chips. Trigger scenarios: (1) Flash firmware to microcontroller, (2) User mentions "flash", "burn", "download firmware", "download", (3) Need to write compiled .bin or .hex file to chip, (4) Program target board via J-Link. Even if user just says "flash it" or "burn the chip", th…

Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

J-Link Firmware Flashing
Invoke py_jlink_download.py to flash firmware files to target chips via J-Link debugger, supporting full process of erase, flash, verify, and reset.
Tool Script
Script Path: py_jlink_download.py Dependencies: Python 3.x + pylink library
pip install pylinkUsage
# Basic usage (default chip GD32F103C8)
python py_jlink_download.py firmware.bin
# Specify chip model
python py_jlink_download.py firmware.bin -d STM32F103C8
# Specify flash start address
python py_jlink_download.py firmware.bin -a 0x08001000
# Skip erase and verify (faster)
python py_jlink_download.py firmware.bin --no-erase --no-verifyParameter Description
| Parameter | Short | Description | Default | | ------------- | ----- | ---------------------------------- | ------------- | | firmware | - | Firmware file path (.bin or .hex) | Required | | --device | -d | Target chip model | GD32F103C8 | | --addr | -a | Flash start address | 0x08000000 | | --no-erase | - | Skip chip erase before flashing | Default erase | | --no-verify | - | Skip flash data verification | Default verify | | --no-run | - | Do not reset and run after flash | Default reset |
Flash Process
- Initialize and connect J-Link
- Connect to target chip (SWD interface)
- Erase chip (optional)
- Write firmware file
- Read memory to verify data (optional)
- Reset and run program (optional)
Common Chip Models
GD32F103C8/GD32F303RCSTM32F103C8/STM32F103RET6
> If chip model is unknown, run JLinkDevices command to view the complete device list supported by J-Link.
Notes
- Ensure J-Link debugger is connected to both computer and target board
- Chip model must exactly match the name in J-Link database
- For
.hexfile flashing, verification step errors can be ignored (hex format contains address information)
