COMPUTEX Introduction of J-STICK
J-STICK
J-STICK is a high-performance JTAG emulator specifically for ARM Cortex-M3.

It supports ARM CoreSight™ technology SWD/SWV.

Rich support for MCUs of various manufacturers
With support for ARM Cortex-M3 core MCUs of various semiconductor manufacturers, it has been made more affordable.
Requires no power supply with USB2.0 Vbus support
-Can be powered by USB Vbus power. AC adapter not required!
Compact design ever
-As you are already familiar, PALMiCE series made by Computex have been palm-sized and compact. For J-STICK, it has been materialized to even lighter and smaller body. 102mm(W)×49mm(D)×22mm(H) / Approx. 50g
Various features that had not been possible only with JTAG now made into reality with SWV
- Profiler feature
Samples execution addresses at certain time interval and analyzes the frequency of module execution based on the times of capture. The feature is useful for identifying the frequently used functions and the functions which occupy much of the time.

- SWV exception tracing
Acquires the information at the time of exception occurrence from SWV and shows the state of exception program execution together with processing time in transition graph. It allows to visually grasp how exception program is processed in flow.

- Printf debugging feature
By embedding the dedicated function in the user program of the target, it implements the functionality similar to Printf of C library. Output destination will be Terminal Window in CSIDE. With this, the history of variable etc. of your choice can be saved to file.

- Time measurement between access data
Measures the time between the specified data accesses.

- Status bar
In the status bar, the target voltage is always indicated by sampling. In addition, it indicates the program counter value of the running CPU. With these, state of the CPU execution can be roughly grasped.
Provided with integrated development environment "CSIDE" Version 5 as standard
Provided with integrated development environment as standard for seamless implementation of development phases from creation of the program to debugging.
CPU break feature
Allows after-execution break of the program and access break upon read/write of data.
NOR-type flash memory support
Supports debugging features such as software breakpoint setting and normal memory rewriting, besides downloading to NOR-type flash memory. Also, new devices can be added easily by using definition file format.
(For some on-chip flash memories, support is provided on optional basis)
Low voltage support and voltage measurement feature
Automatically follows the target voltage between 1.1V - 3.45V in operation. Also, the target (VTref signal) voltage value can be indicated.

To assist debugging of the target program using OS, optional debug library softwares have been prepared for each OS. Use of the debug library will add features for OS state indication, program operation check, etc.
µITRON support
By additionally purchasing optional RTOS Debug Library besides debugger software, task tracing feature and status display feature for real-time OS will be added.
(Specifications vary by µITRON.)
