I think you need to use another app_error_handler .c file here, as the gcc version isn't recognized by the project. Which one exactly I don't know exactly, but you can try \components\libraries\util\app_error_handler_iar.c

Best regards,

For your project to be able to discover the header file in a said nRF5 SDK project, you need to add the folder where this header file is located to the project's user include directories. Please refer to the SEGGER blog post available here.

Hello,Do I need to download any other toolchains besides the nRF5 SDK when developing NFC with this board? When developing NFC, I found that several header files cannot be found, and I still can't find them even after re-downloading the SDK on another computer.

RE: 环境搭建

Simonr — Thu, 16 Oct 2025 07:48:17 GMT

Yes, correct. v5.42a was the last version we did extensive testing/verification for, and if I recall correctly there has been issues with newer versions of SES and the nRF5 SDK.

Best regards,

Simon

RE: 环境搭建

wt1 — Wed, 15 Oct 2025 13:35:10 GMT

Hello,The version I'm currently using is 7.32a. Are you suggesting that I switch to version 5.42a? Thank you very much for your help, and wish you a pleasant life.

RE: 环境搭建

Simonr — Tue, 14 Oct 2025 06:27:18 GMT

What version of the SEGGER Embedded Studios (SES) have you downloaded and have started working on? The nRF5 SDK v 17.1.0 was tested and verified with SES v5.42a, so if you have another version than this one I strongly recommend you move to the tried and tested SES version. Unfortunately I'm not aware of a cc1 or ccl file being necessary.

Best regards,

Simon

I have first reviewed my mistakes. I have tried all the methods obtained from the search results of the large language model, and also deployed the development environment accordingly. However, I still cannot solve this problem.

RE: 环境搭建

wt1 — Sun, 12 Oct 2025 03:56:53 GMT

If possible, I hope you can take control of my computer to help me solve the environment configuration problem.

RE: 环境搭建

wt1 — Sun, 12 Oct 2025 03:54:37 GMT

Hello, when I was deploying the environment in the software you provided and installing the GNU Arm Embedded Toolchain, I asked AI about it. It told me that I needed a file named ccl. However, I downloaded the latest version from Arm, but there was no such file in its bin directory. Re-downloading it multiple times didn't solve this problem either.

RE: 环境搭建

Simonr — Fri, 10 Oct 2025 06:41:34 GMT

On the nRF52833 DK there is already a J-Link debugger MCU on the board that lets you program and debug the nRF52833 on the DK.

Best regards,

Simon

RE: 环境搭建

wt1 — Thu, 09 Oct 2025 12:34:47 GMT

Hello, I would like to ask if a J - Link debugger must be used when SEGGER Embedded Studio is used for software development related to the nrf52833dk.

Thank you very much

RE: 环境搭建

Simonr — Fri, 26 Sep 2025 07:48:52 GMT

It seems like you're trying to build/rebuild the SoftDevice itself, which shouldn't be necessary. You should build the application and not the SoftDevice component. Then flash the .hex for both onto your board. Either with Keil, SEGGER Embedded Studio or the nRF Connect for Desktop Programmer application.

Note that we recommend using SEGGER Embedded Studios for developing nRF5 SDK projects. You get a license by owning an nRF52 series device and is generally easier to get started with than Keil µVision and the nRF5 SDK in my opinion.

Best regards,

Simon

Hello, thank you very much for your reply. The software I am using is Keil5, but I encountered a problem when burning the relevant protocol stack.It shows that this file cannot be found. After I changed it to a normal file, when I ran it again, another file couldn't be found. When I modified that one again, the first file became unavailable again.

This makes me very confused. I don't know how to modify it to proceed with the next operation. The relevant reference materials I found in China don't mention how to solve this problem.

In the future, please ask your questions in English, as we try to keep this forum in one language for all users, and our tech support engineers have English as our common language. I had to translate your question so I might have misunderstood, but it seems you're using the nRF5 SDK (in maintenance mode) on VS Code, and I think you're mixing the SDKs here. For new designs it's strongly recommended to use the nRF Connect SDK and not the nRF5 SDK and SoftDevice solution. I'd recommend that you begin with the DevAcademy courses which are great to get started with developing with our VS Code extension.
