I'm getting FreeRTOS crash in the "wifi_setup" example imported from SDK.
Here's a tail of the debugging session output:

<signal handler called>@0xfffffffdIf I look at pxReadyTasksLists array in the debugger, it shows that its 2nd element has uxNumberOfItems == 1 but pxIndex points to xListEnd. At the same time, xListEnd->pxNext and pxPrevious point to "tcp/ip" task. I've attached a screenshot.
My setup:
- MIMXRT1060-EVKB board
- MAYA-W161 M.2 Wi-Fi card
- I have the resistors resoldered on the board to enable M.2 connector.
- I'm using Visual Studio Code with MCUXpresso for VS Code extension
- I've imported MCUXpresso SDK Repository version 25.03.00 (I've checked version 25.06.00 but it made no difference)
- I've imported the following example from Repository: wifi_examples/wifi_setup, as a Freestanding application.
- I've also made a wrapper for tcpip_input function to print something to the debug console.
As my Wi-Fi card isn't readily available in the choice of cards, I've made the following changes to the SDK sources:

Empty diff in 91 projects.My wrapper function looks as:
err_t wifi_tcpip_input_wrapper(struct pbuf *p, struct netif *netif)
{
PRINTF("In wrapper\r\n");
const err_t result = tcpip_input(p, netif);
return result;
}So there's nothing criminal there, just calling the original function. The crash happens after "In wrapper" is printed to the console, when the software should switch to "tcp/ip" task.
There's a similar post on FreeRTOS forum: https://forums.freertos.org/t/incorrect-pxreadytaskslists-state-causes-fault/17791, only in my case pxCurrentTCB is correct, pointing to "Tmr Svc" task.
The solution to that topic was an incorrect interrupt priority. I tried setting all NVIC->IPRn registers to 0xF0 at the beginning of the program to set all priorities to the lowest possible level but that didn't help. I also checked the stacks -- they are fine. I can attach my project or upload it anywhere if that helps.
If I don't use wrapper function, so that the SDK code calls tcpip_input directly, the example works but sometimes I get delays in ping responses of like 1600 ms which is strange because I ping my local router. So I suspect the bug is still there but adding a PRINTF makes it more apparent.
