Error downloading Thread_SED_Coap_FreeRTOS

[ZB.1]

Hello there

I am using the official engineering code Thread_SED_Coap_FreeRTOS. When downloading with STM32CubeProgrammer, the error message connection to device0x495 is lost appears. At this time, the program should fail to download because the LED1, LED2, and LED3 on the board are not lit, so I want to use it again When downloading programs on this board, STM32CubeProgrammer reported an error ERROR:NO STM32 TARGET FOUND. What is causing this? I downloaded other project codes normally.THANK YOU

Hello @ZB.1​ ,

Welcome to the STM32 Community 😊.

Which version of STM32CubeProgrammer are you using ?

I see that you are using an old version of STM32CubeWB firmware package (v1.8.0).

Please ensure to use the latest version of the STM32CubeProg tool (v2.6.0) and STM32CubeWB firmware package (V1.10.0).

If this issue is reproduced with latest release, please provide more information about your board, which may help to reproduce this behavior.

Hello, thank you very much for your answer. I am sure that I have upgraded the STM32 CubeProgrammer to the latest version, and I am using the version V1.9.0, but the problem still exists.I only found 1.9.0 STM32CubeWB on the official website.Hope to have a solution soon, thank you

I have tried the latest firmware package STM32CUBEWB V1.10.0, but it still fails。

Hi @ZB.1​ 

Can you please try to connect with "Under Reset " Mode instead of "Normal" mode?

Thank you very much for your answer. Under your suggestion, I tried again, but the problem was still not solved, and I didn’t see the effect that this project should have.
