Fixed Issues

IDE-81186 Reset before download doesn’t seem to be invoked. (GDB Server RZ)

Affected device families:Synergy RZ RA DA

When debugging with the Segger J-link with ARM devices such as RA, when you set "Reset before download" to Yes, the reset operation does not take place.

IDE-81742 [RZ/A] Breakpoint in SDRAM Causes e2studio to Fail CPU Reset and Timeout on Suspend (ARM GDB)

Affected device families:RZ

When debugging RZ devices, if a reset is invoked, when PC is on a breakpoint which is on the external memory where can’t be accessed on the reset state, the further debugging may fail. In this case, reset the program after removing the breakpoint, or use Restart instead of Reset with the command "set breakpoint enable-memread 0" (Please specify the command at "Initialization Commands" on Startup of the debug configuration).

Open Issues

IDE-77369 RZT2M not support semihosting with E2 emulator (Debugging RZ)

Affected device families:RZ

For the RZ/T2M device e2 studio does not support semihosting with the E2 emulator

IDE-66594 Cannot debug RZT2M in Linux (RZ FSP)

Affected device families:RZ

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

IDE-73531 Connection will fail when the program is large. (Debug Launch)

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

  1. Select [Window] → [Preferences] menu in main menu.

  2. Select [C/C++] → [Debug] → [GDB] node in [Preferences] dialog.

  3. Change the value of [Command timeout (ms)] text to more large value.

  4. Or uncheck [Command timeout (ms)]

IDE-62641 PC doesn’t stop at the reset vector on reset for RZ. (Debugging RZ)

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.

IDE-72790 [RZA3UL] Program is disconnect automatically after resumed (GDB Server RZ)

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.

IDE-80756 Program is automatically disconnected when resuming until stop at main (Debugging RZ)

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.

IDE-84737 [RTOS plugin] Support AArc64 Azure RTOS(RZ/A) in the RTOS resource view. (Partner OS plugin)

Affected device families:RZ

The resource information display for programs using Azure RTOS in the RTOS resource view only supports AArc32.

The correct resource information is not displayed for AArc64.

IDE-83532 The run break time measurement status bar does not work. (GDB server)

Affected device families:RZ

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

IDE-83535 Trace View does not work when debugging with RZA3UL (Trace plugin)

Affected device families:RZ

When using Cortex-A/R devices with J-Link, if the device supports ETF as trace buffer, trace view doesn’t show the data.
