The nice new Raspberry Pico can be easily programmed by USB-uploading an
IntelHex file through its "SD-card" interface. Should be just as simple as
with Micro:Bit programming: openup like a USB-stick and drag a file to a
window.
For Micro:Bit this works on any system, including RISC OS, but to my
disappointment the RPi Pico fails on ARMX6.
SCSIFS accepts the Pico as an "USB-stick", but CDFS doesn't recognise its
fileformat: "Has it been formatted?" Yes, it certainly is! However not in
FAT32 (as you might expect) but in good old FAT16 format. And RISC OS 5.29
apparently is too modern to accommodate DOS antiques..
Do we have to re-design a RISC OS 32bit FAT16FS module? Or is it still
around?
Might be worth *rmkill-ing Fat32FS. I have seen some (small) discs not
play ball with FAT32FS so there are times when falling back to vanilla
DOSFS can help.
I don't know enough about the Pico specs to know how much storage it is
offering, but I'd guess it is probably measured in MBs rather than GBs.
As such, I could imagine DOSFS might work better.
DOSFS is in ROM, and will be used it FAT32FS isn't loaded.
Hope this helps,
Andrew
