Tried to reproduce with the driver source code but didn't get the hard fault. We will look it soon.

Running out of memory. I did say from the heap traces that in this case heap allocation did fail.

[mikaleppanen]

Made a pull request to increase the heap on IAR. https://github.com/ARMmbed/mbed-os/pull/7289

@asifrizwanubx We are seeing an increase on heap usage on Odin wlan driver during initialization from 5.8 to 5.9. Are e.g. the thread stack sizes allocated by driver optimized?

[asifrizwanubx]

@mikaleppanen there is no change/update in drivers related to thread stack sizes.

[asifrizwanubx]

But there are changes related to memory allocation, static memory allocation mostly changed in drivers. @mikaleppanen

[screamerbg]

@mikaleppanen @asifrizwanubx Is the https://github.com/ARMmbed/mbed-os/pull/7289 PR fixing this issue?

[mikaleppanen]

Yes, tested mbed-os-example-client with the changes and error does now occur anymore.

[asifrizwanubx]

yes, I have verifed it.

[0xc0170]

Thanks for the verification !

[0xc0170]

Not yet merged, too fast closing :)

[JanneKiiskila]

When will this get merged? Known issue list with the Mbed OS boards is just getting longer and longer...
