Affected device families:Synergy RZ RX RL RE RA

When debugging RZ, RA, RE, Synergy, RX, or RL78 and when the option "RTOS integration in debug view" is enabled, the debug connection may be disconnected when a thread is deleted while debugging. Please don’t enable the option "RTOS integration in debug view".

Affected device families:Synergy RZ RX RA DA

When a project contrains identically named static functions the Stack Analysis view does not distinguish between them. This can be seen with the GCC toolchain.

Affected device families:RZ

Importing older RZ/A FSP projects from 2024-10 can cause build errors following import:

Error messages can be seen friom the build such as:

Assembler messages:

Error: selected processor does not support `crc32cb w0,w0,w3' {code}

To fix:

Configure Enable to Feature crc on the Target Processor field.

Add -mcpu=cortex-a55 to Other target flags.

When using Eventpoint view for RZ devices, the timer start/stop events or the trace start/stop events would not be supported.

Affected device families:RZ

The run break time measurement which is shown in the status bar does not display values for the RZ/A3UL.

Affected device families:RZ

RZA3UL with FreeRTOS requires a breakpoint at main() in order to be able to debug threads.

It is necessary to stop at main() for the debugger to detect that the RTOS symbols are accessible.

While debugging, if the reset or restart operation is invoked while the program is running, the debug connection may be disconnected. Please push the reset or the restart button while the program is suspended.

Affected device families:RZ

When debugging RZ devices, if debug view shows data which is located on the area where is not readable on reset, the next resume/step operation may cause a disconnection of the debugging. Please close the view until the area is readable.

When the program need to be reset, please use 'Break at' for the address where the area is readable on the startup tab, and use 'restart' instead of reset to run the program to enable the debugger to read the memory.

Affected device families:RZ

Debugging on Linux with RZT_FSP v1.2.0 for RZ/T2M or RZ/T2L is not supported.

Affected device families:RZ

When debugging RZ devices, PC will not stop at an address of reset vector on reset. Program will run in a short time after reset, and then, the program will be halted.

If the program is built for RAM debugging (without using boot loader), the program will not run after reset correctly. In this case, please re-download the program (please don’t forget to set "Reset after reload" option to 'No' on Debug Configuration) after reset, or disconnect the debugging and re-connect.

Affected device families:RZ

When debugging CR52_1 on RZ/T2H, the debug connection may fail with the default lauch settings. In this case, please specify "Prevent Releasing the Reset of the CM3 core" to 'Yes'.

Affected device families:RZ

On Ubuntu 22.04 and 24.04 the RZ/G1E via TCF connection will not start. The issue is a dependency on python 2.7 which is not present on these systems. Check this link for an update http://security.ubuntu.com/ubuntu/pool/universe/p/python2.7

Affected device families:RZ

For RZ/T FSP multicore projects that utilize linked projects, it’s crucial to maintain consistent FSP versions across all linked projects. Inconsistencies can cause unexpected problems. Currently, e studio does not notify you if the FSP version of a linked project doesn’t match the FSP version of its smart bundle’s parent project.

Affected device families:RZ

Debug connection may fail due to time out when downloading a large program.

In this case, please reconfigure the time out setting of GDB in [Preferences] dialog.

Please follow below steps to reconfigure the time out setting of GDB

Affected device families:RZ

When debugging, if a variable which can’t be accessed on reset is added to Expressions view, the next connection or resume may fail. In this case, please disable the variable on the Expressions view before connection or reset.

For example, the variable is located at external memory area and the area is disabled on reset and if the memory access for the disabled area causes an exception in the device, this issue will happen.

Affected device families:RZ

The RTOS integration in Debug View feature is not supported on RZ/T2H devices.

Affected device families:RZ RA

In the Pin function page, a redundant "*" character may be displayed in the "Input/Output" section of the GPIO pin configuration panel after a DTSi configuration file is imported.

Affected device families:RZ RA

In the case where a solution pin setting is overwritten in downstream project, and if the user modifies the same pin again in a further downstream project, the pin assignment may not be generated into pin_data.c

To avoid this issue, please do not override a solution pin setting more than 1 time.

Affected device families:RZ RA

The lock function of the Pins page may not work correctly if the locked pin assignment is changed manually from the pin number page or FSP Visualization view.
