Linker issue with BLE demo of QN9090DK6

[Palstek]

Hi all,

I run into issues when trying to compile any of the ble demo projects of the QN9090DK6. Errors akin to:

signalr.c:(.text._kill_r+0x12): undefined reference to `_kill'

Appear for all projects. Now I have read that this may be a lib-setting problem. But I have tried semihosted and it still does not work.

Any ideas on what this could be? Is there a need to set the correct lib settings? If yes can you give me an example, e.g., for the qn9090dk6_wireless_uart_freertos demo?

Additional infos:

• Simple projects (such as hello world) work without any issues
• Had the same issue on two separate machines
• Could this be related to some problem with my toolchain installation? When I try to swich the lib type using "Quick Settings -> Set library/header type" none of the options are selecteable.

Thanks for your help

Hello,

Hope you are doing well. Could you please clarify the following information?

• IDE version
• SDK version
• If any modification was done to the SDK example.

Could you please help me confirm the steps from section 3 of the QN9090-DK006 Development Kit Getting Started?

Best Regards,

Ricardo

Hi Ricardo

Thanks for the quick reply.

• IDE version: MCUXpresso IDE v11.10.0 [Build 3148] [2024-07-03]
• SDK: SDK_2.x_QN9090DK6 version 2.6.15
• I have not modified the SDK example. The only thing I have modified (and tried different ones) was the lib type after it failed with the default setting.
• I can confirm I have followed all steps in said document:
  • MCUXpresso SDK downloaded with all features and added to MCUXpresso
  • MCUXpresso IDE installed
  • Connectivity QTool installed, DK6 production flash programmer tested (it works)
  • Python 2.7 installed, added to PATH and pycryptodome installed
• All done on Windows 11 OS (both machines on which I tried)

Best,

Hi,

Thank you. According to the MCUXpresso SDK Release Notes for QN9090 (v2.6.15), the SDK was compiled and tested with MCUXpresso IDE version 11.9.0.

Could you please try with this IDE version?

Please let me know your findings.

Regards,

Ricardo

Hi Ricardo

Thank you for pointing this out. This has solved my issue, the examples compiles just fine with the older IDE.

Or in other words: the SDK is not fully compatible with the latest IDE.

Best,
