PALMiCE4 JTAG Emulator

Model-JJTAG model

For normal debugging

Standard model with excellent cost performance that enables source level debugging such as Go/Break/Step execution of programs.

PALMiCE4 supports unstoppable system debugging with three features.

1. Hot plugin debugging
2. Real-time monitor
3. Trace

1.Connect to a system that is running [Hot plugin debugging]

Debug in the field/test environment without turning off target power

The target can be debugged without turning off its power. Problems that occur when the target is operating can be debugged easily. Variables, peripherals, and program execution related stuff can be checked by combining Real-time monitor and trace feature.

• A phenomenon occurring in the field can be debugged/analysed later.
• Timing is off in printf log
• A phenomenon that cannot be reproduced when a break occurs
• Rewrite a value to a port and see the change when a problem occurs

2.Check data in real time [Real-time monitor]

Variables and peripherals can be analysed and changed without stopping the program

Memory changes can be monitored in real time without changing the program. As one of the applications, this feature can be used for parameter adjustment of control equipment and detecting abnormal values.

• Real-time graph display of variable and peripheral values
• Get fast data with hardware sampling (fastest 10µs)
• Variable values can be rewritten during execution
• Start/end recording when the set condition is satisfied
• Values can be saved to a file in real time (CSV format is supported)

3.Check the program in real time [Trace]

Check execution information and flow without stopping the program

With the Trace feature, one can analyze the operation of the program even while the program is running. As an example, it is possible to investigate the cause of a deadlock or infinite loop that has occurred currently.

• Capture and display trace during execution
• Visualize programs in the form of function calls
• Available for both Arm internal and external traces
• Displays RTOS tasks and Linux process information
• Supports instruction level debugging with assembly view

For software engineers - Logic analyzer function

Utilize large-capacity trace memory as a logic analyzer

By connecting an external probe, PALMiCE4 can be used as a 4-channel logic analyzer. Software engineers can check I/O and signal values with ease.

• Waveform display of 4 digital signals at the same time
• Sampling frequency up to 200MHz
• Time measurement between set marks
• Waveform pattern search

Equipped with Integrated Development Environment CSIDE Version 7

PALMiCE4 comes with an advanced integrated development environment that is really easy to use.

• Bug detection function
• "C macro" feature that is fully compatible with C language
• Easy source browsing
• Easy variable display with quick inspect
• Instruction-level debugging with line assembly
• View and change memory, registers, coprocessor
• Display and change bit-by-bit I/O
• Stack display and function stack trace
• Freely set font and window color scheme
• Download multiple object files with just one click
• Can be operated with mouse gesture control

Bug detection function

Detect array overflow etc. when executing a program!

Memory corruption that is difficult to notice during normal tests can be detected facilitating early detection and fixing of bugs.

• Detect bugs that corrupt arrays and heaps at run time
• Select the target source and build the program to include this feature
• The source line where the bug was detected is shown and execution breaks
• Variables and stack traces at the time of detection is displayed
• Independent of target CPU

Read/ write serial flash memory connected to SPI multi-I/O interfaces and bus controllers such as RZ/A1L and RZ/A1H.

• Write and read with file load and file write functions
• Rewrite data while preserving data that has already been written
• File loading support for binary, Motorola S, Hexa, ELF files
• Support for various serial flash memories via different write monitors

Real-time OS support

Display status of Real-time OS and task trace functions. (Specifications vary depending on the real-time OS.)

Embedded Linux support

Supports for multi-process/multi-threaded debugging in addition to seamless debugging in all scenarios starting from kernel, device drivers to applications. (Specifications vary depending on distribution.)
