# Version 0.3.16

> January 26, 2026

## <u>Features</u>

### J-Link Script File Support

* Added support for custom J-Link script files (`.JLinkScript`) in debug commands
* Scripts can be passed to enable advanced initialization sequences for custom hardware configurations
* Useful for enabling trace clocks, custom target initialization, and specialized debug setups

### Expanded Device Support for J-Link Debugging

* Dramatically expanded ARM architecture detection to support 70+ device families
* Now supports: Nordic (nRF51/52/53/91), STM32 (all families), NXP (LPC, Kinetis, i.MX RT), TI (Stellaris, Tiva-C, CC26xx), Microchip/Atmel (SAM), Silicon Labs (EFM32/EFR32), Renesas (RA), Dialog, Infineon, and more
* Unknown devices now gracefully fall back to a default architecture instead of failing

## <u>Bug Fixes</u>

### Resource Busy Error Fix

* Fixed "Resource Busy" errors when reconnecting to VISA/USB instruments
* Devices are now properly closed before being removed from the cache
* Added cleanup handler on process exit to release hardware resources

### Debug Reset Reliability

* Improved debug reset reliability for Cortex-M33 devices (e.g., nRF5340)
* Reset and memory read operations now use J-Link Commander directly, avoiding GDB register mismatch issues

## <u>Improvements</u>

### Robotic Arm Enhancements

* Increased default arm move timeout from 5 seconds to 15 seconds for more reliable operation
* Improved out-of-bounds error messages now show which coordinates are invalid and display workspace limits
* Updated Rotrics Dexarm workspace bounds to accurate values

### Silent USB Hub Operations

* USB hub enable/disable/toggle operations now complete silently for cleaner automation output

### Python Compatibility

* Added Python 3.14 support
* Updated dependencies for newer Python version compatibility

## <u>Installation</u>
