Might be user error... about cyw43439 HOT 5 CLOSED

Does this happen with the DHCP example too?

from cyw43439.

I haven't tried it with that. I will try it tomorrow and report

from cyw43439.

I get this output:

And it just stops there.

I've run into this issue many times since, it's always because I forget to add the -stack-size flag to the compiler. This then results in a runtime stack overflow. Use 8kB of stack size like so:

tinygo flash -target=pico -stack-size=8kb main.go

from cyw43439.

Success! Thanks very much! Clearly I ran into the same issue.
