I just learned the hard way that timers do not work when you debug an
app for the Pico. Which makes short delay loops take forever....

A good summary is here:

https://github.com/raspberrypi/pico-sdk/issues/1622

So, when you face the same issue this commandline will solve it:

openocd -f interface/cmsis-dap.cfg -c "set USE_CORE 0" -f
target/rp2040.cfg -c "adapter speed 5000"

Have fun,

Michael

Thanks for the tip.  I hope I remember this when I eventually get
round to playing with my Pico.

Funny, I deleted the topic here and put it to the arm forum, seems
that delete was not successfull.

Anyway, now you have two places to remember..
