hmmm ... I provided a stable 4V supply for VSYS from a desktop power source,
also tried hard resets and some additional delay at startup, but the problem persists...
I was searching for the check of WL_GPIO2 in the driver code but could not find it; I expected i somewhere here:
https://github.com/georgerobotics/cyw43 ... ctrl.c#L83
I then tried to force WL_GPIO2 high using but although that seems to work (subsequent reads show HIGH), calling this before the CYW43 driver init causes the initializiation to hang.
Well, as the HW workaround (connecting WL_GPIO2 to 3,3V by attaching a wire to the voltage divider R1/10) works
and it seems that this issue doesn't exists on other boards, it's not a big deal!
