Hello everyone,

I am evaluating with DEV_KIT_NAC1080.
https://www.infineon.com/cms/jp/product/evaluation-boards/dev_kit_nac1080/

When I was debugging with Eclipse and SEGGER J-Link debugger, the following error occurred.
- Please refer to the attached document for detailed information.

This caused me to be unable to use J-Link debugger to access the NAC1080 device.
- Including writing programs to Flash and debugging the software.

Maybe I accidentally erased the Flash of NAC1080 device while using J-Flash to write programs.

Could you tell me how to restore the device to its original state?
- How to achieve flash recovery for NAC1080 device?

Best Regards

Hello,

Please answer the following:
1. Which firmware example you are using?
2. Are you able to build the project without any issues?
3. Can you share the Jlink configuration settings?

Thanks,
Ajeeth

Hello, Ajeeth

Thank you for your respons!
Let me answer your questions.

>1. Which firmware example you are using?
I am using the "Infineon-Infineon_NAC1080_Firmware_Sample_Boost_Buck_Test_Firmware-Software-v01_00-EN" provided on Infineon website.
https://www.infineon.com/dgdl/Infineon-Infineon_NAC1080_Firmware_Sample_Boost_Buck_Test_Firmware-Sof...

>2. Are you able to build the project without any issues?
Yes, I created and compiled the program using "Eclipse IDE for Embedded C and C++ Developers - 2022-12" as per the instructions below.
https://www.infineon.com/dgdl/Infineon-NAC1080_software_development_guide-UserManual-v01_00-EN.pdf?f...

I can use SEGGER JLink to debug programs on DEV_KIT_NAC1080.
However, when I tried to write the "Infineon NFC Lock Showcase Firmware for NAC1080" software (lock_demo_v0-1-5-2_A21004_HW3-0.hex) provided by Infineon's website into DEV_KIT_NAC1080 using SEGGER J-Flash Lite V7.86d, the above problem occurred.
In this operation, I may have clicked the "Erase Chip" button.
About the screen of SEGGER J-Flash Lite V7.86d please refer to the attached file.

>3. Can you share the Jlink configuration settings?
Of course. About my 'Eclipse IDE' settings please refer to the attached file.

Best Regards

Hi,

Did you update the JLinkDevices.xml file with the contents mentioned in the NAC1080 Software development guide?

Please ensure the "Loader" field is the proper path with the Image file name. 

Thanks,
Ajeeth

Hello, Ajeeth

Thank you for your respons!

Yes, I updated the JLinkDevices.xml file according to the NAC080 software development guide.

I still cannot use Eclipse IDE with SEGGER J-Flash to write firmware.

When using SEGGER J-Flash, I can find the NAC1080 device when creating a new project.
After generating the project, I was able to successfully read in the ".elf" and ".hex" files. However, when I tried to connect to the device using the "Connect" option under the "Target" menu, I encountered an error as shown in the attached file, which prevented me from connecting to the device.

When using Eclipse IDE, the error message 'Device 'NAC1080' Flash bank 0x0001 0000' No loader specified' appears. 

This prevents me from writing firmware.
I have attached the output information from the 'Console' in Eclipse IDE for your review.
