New Flash API, and nice surprise for Pico owners!

Hi Gorden
Sorry, something goes wrong with 1.82. This code worked with 1.81. Now the Pico crashes with the following on the console:

>ff = process.memory().flash_start + 384*1024;
=134610944
>f=require("Flash");
=function () { [native code] }
>f.erasePage(ff);

After reinsert the pico into USB, the red LED is on permanently. Have to reflash to access the pico.

Thanks
