Recently purchased 3 new modules , plug into USB port (old Lenovo T450 / Win10). No LED blinking, modules listed correctly in file manager.Flashing MMbasic appears normal on the screen, after this still no LED . Flashed again with the clear flash file, still the same. Device mngr says "RP2 BOOT , Driver not availabl". Tried all this again on another Win PC , same outcome. The same USB cable connects fine with several other 2040s I have here. The 3 modules with this anomaly also can't get their ports detected in MMEdit. Can anyone give me some idea what's wrong ?
Kind regards, Hans

Hello.

I'm assuming you are following this procedure:

1) HOLD DOWN the "BOOT" button, plug in the USB cable.
2) COPY and PASTE the .uf2 MMBASIC FW file to the "Flash-drive" that Windoze will have detected.
3) The RP2040 will automatically reboot when finished, and the "Flash-drive" will vanish.
4) Open a terminal software such as GFXterm.
5) Connect to the VCP(virtual serial port) that Windoze will have assigned to the module (38k4 baud, 8N1)

At this point, you should be able to talk to the module using the command prompt.

Simply pressing ENTER, should result in the module responding with the ">" prompt.

Can you get that far?

Exactly what RP2040 module are you using?
The official Raspberry Pi module? (or a clone of it)
A Waveshare variant with an LCD or other feature on-board?
A Waveshare 2040 Zero module?

Ensure you are using the correct FW version - there a several different ones, depending on what feature set you want. The bog-standard 2040 PicoMite FM is called: "PicoMiteRP2040V6.00.03.uf2" (the version number may be newer)

Be certain you are not using one of the other versions designed for VGA etc.

Hi Grogster,
Have actually been using the (Altronics) RP2040 modules since many years , never had a problem. But mostly I use the STM23F4 pcbs , mainly because they easily worked with the larger TFT panels. More recently I started using the RP2040s again (for small projects), and of course no problems with them because they are not new ones. But the recent 3 pcbs I can't get the FW loaded. If I load the clear flash file , it seems to operate correctly, the window closes immediately after. But not after loading the FW.
Obviously I'm doing something wrong , but simply cant figure out exactly what.
Probably I'm getting too old (82) for this , or something like that....

AWESOME!!!

Yes, there IS some confusion around the PicoMite series specifically, as there are several versions, and - as you have just discovered - different versions of the chips. (2040 vs 2350)

For the FW to work, you have to make sure you are using the correct FW for the correct silicon version, and as mentioned, the PicoMite series has quite a few variants now!

WELL DONE getting it sorted.
You should be pleased with yourself.
