KW41Z With SDK2.2.3 HardFault

[agalliazzo]

Dear sirs,

While trying to use the SDK example frdmkw41z_wireless_examples_thread_end_device_freertos (but it happen also with router eligible thread end device) I can join the device to the thread network created with Openthread but every time I try to send something pushing a button the KW41Z enter in an hard fault condition.

Querying the board though serial port works.

I'm not able to debug the Hardfault cause it point to strange stack position.

Does anyone have some advice?

Hi,

Do you just use the example without any modification ?

Have a great day,

Hi, yes, it's a brand new demo project. No edit in the files. The network leader is an OpenThread based border router with a nrf52840 RCP.

With other development board from Nordic the network works without issues.

Hi,

I test on two frdm-kw41. It woks well. So may be the kw41 has compatibility with other company's product. I do not have the Nordic product. I also can't test this problem.
