<p>Thanks for the fill and resource! <br>

<p>Sorry to see Newark isn't a supplier for the sake of their SC
warehouse. Adafruit is out already, but others have stock.<br>

<div>Perhaps this will help with the icache question... <a href="https://github.com/raspberrypi/pico-examples/blob/master/flash/cache_perfctr/flash_cache_perfctr.c" target="_blank">https://github.com/raspberrypi/pico-examples/blob/master/flash/cache_perfctr/flash_cache_perfctr.c</a><br>

Also, at the moment, the OS is not real time, so the second

<p>What I haven't dug out yet is whether there is any
icache and if they really mean that ALL flash outboard.
That would make for absolutely wretched instruction
