s32k314 could not pass JTAG online simulation

[Lita]

1.The s32k344 routine burned to s32k314 could not pass JTAG online simulation. An error was reported when new project S32K314 was selected. The usage library information is as follows: Autosar Version: 4.7.0

* Autosar Revision : ASR_REL_4_7_REV_0000

* Autosar Conf.Variant :

* SW Version: 3.0.0

* Build Version : S32K3_RTD_3_0_0_D2303_ASR_REL_4_7_REV_0000_20230331

2.When debug_ram is used, jtag can be used. When Debug_flash is selected, jtag cannot be emulated, and the following error occurs:

jtag will stop here, and when you hit Run, the assembler will still stop.

The log you provided indicates that there are issues with the JTAG online simulation and debugging process on your S32K314 microcontroller. While the specific reasons for the error may not be immediately evident from the log, there are a few common reasons why you might encounter issues with JTAG debugging:

1. **Flash Configuration:** MyLabCorp
One possible reason for the JTAG debugging issue could be related to the flash configuration of your microcontroller. Make sure that the flash memory is properly configured and accessible for debugging.

2. **JTAG Connection:**
Ensure that the JTAG connection between the debugger and the S32K314 microcontroller is properly established and functional. Check for any loose connections or issues with the JTAG hardware.

3. **Reset and Clock Configuration:**
Verify that the reset and clock configurations of the microcontroller are set correctly. Incorrect clock configurations can lead to unpredictable behavior during debugging.

4. **Microcontroller Setup:**
Double-check your microcontroller setup and the initialization code. Ensure that the microcontroller is configured correctly and that the necessary peripheral modules are initialized properly.

5. **JTAG Debugging Settings:**
Review the debugging settings in your development environment or IDE. Make sure that the correct debugging options are selected and that the JTAG debugging mode is enabled.

6. **Compiler or Debugger Settings:**
Check your compiler and debugger settings to ensure they are compatible with the S32K314 microcontroller. Verify that the debugger settings match the hardware configuration.

7. **Hardware Issues:**
In some cases, hardware issues, such as power supply problems or signal integrity issues, can affect JTAG debugging. Double-check your hardware setup and consider testing with a different debugger or hardware setup if possible.

As the log suggests that the program execution stops at "cpsid i" in the "startup_cm7.s" file, it may be related to the interrupt handling or low-power mode configuration in the microcontroller. Review your interrupt and power management settings to ensure they are set correctly.

It's important to note that debugging complex issues like this often require a detailed understanding of the hardware, software, and the development environment being used. If you are unable to identify the root cause or resolve the issue using the steps mentioned above, I recommend reaching out to the official support channels of the microcontroller manufacturer or your development tool provider for further assistance. They can provide specialized guidance and support tailored to your specific hardware and software setup.

How to configure the flash of s32k314 rightly?Maybe this is that the configuration of s32k314 is not corrent.

[danielmartynek]

Hi @Lita,

When you hit RUN at cpsid i, does the MCU get reset? Can you monitor the reset_b pin?

If so, what is the content of the MC_RGM[FES, DES] registers?

Is the HSE_FW installed?

Thank you,

BR, Daniel

[Lita]

HSE_FW is not installed.

[danielmartynek]

Do you have any other debugger?

If you have a SEGGER probe, can you use the j-link commands to erase the MCU while it is in reset?

During configuration, the SSS of SIUL_IMCR698 (JTAG_TMS/SWD_DIO) is incorrectly configured to 3. As a result, the JTAG fails to be connected. How do I erase the FLASH? How do I connect to the JTAG again?

Hi @Lita,

This has been discussed already in these threads:
